After some minor surface prep to lightly scuff the fresh epoxy fillets securing the settee fronts, I prepared a small batch of the filleting material and filled in the several areas where the temporary glue blocks had been installed.  While that gelled, I cut, then wet out and installed, two layers of tabbing along the full lengths of both settees.

While it was on my mind, I took a moment to apply some fairing filler to the top corners of the new mast step structure, filling a small gap between the fiberglass on the top and the tabbing on the two vertical faces–this just as a cosmetic concern, to avoid a sharp edge or gap that would tend to attract debris.

Next, I installed a full-length cleat along the top edge of the starboard settee front to eventually support the berth top and provide additional stiffness to the structure.  I attached this with glue and screws from inside.  I had a twin piece cut for the port side, but for the moment decided to focus on the starboard side.  Afterwards, I installed a short vertical cleat to support the divider bulkhead, then finished the layout of this bulkhead by securing it to the cleat with two screws, squaring it to the settee front, and marking the hull accordingly.  To hold and align the divider during installation, I installed a temporary hot glue block near the outer edge.  Finally, I used a level to mark the top edge of the divider, after which I removed the panel for final trimming, epoxy coating of the edge grain, and then installation with glue and screws against the support cleat, and epoxy fillets along both sides where the bulkhead met the hull.  I left this to cure for now, and planned to install tabbing next time, once the epoxy cured.  I left a sizeable limber at the base of the divider (and also a space for hoses to run later), and provided a wiring chase at the top edge for the existing wire run through the space.

I continued work on the starboard side berth top, partly because I was anxious to have a flat work surface as soon as possible, and partly because the still-curing tabbing on the port side precluded work on the divider bulkhead there, as I’d need to release the large wire bundles in order to lay it out.   With some basic measurements of the space, I cut a template panel from junky plywood, which fit surprisingly well given its rough initial layout, but still required scribing and a second cut to match the curvature of the hull properly.

Once I was satisfied with the outboard edge of the template, I transferred the shape to a piece of the 12mm okoume and cut out the actual berth top, leaving it a bit wide so it hung over the vertical settee face for now.  I’d trim that to final size later, and there was still work to be done beneath, so it’d be a bit before I completed the final installation of the berth top, but at least now I’d have somewhere to put tools and such while I continued on the opposite side.

Laying the pattern for the starboard settee front on a piece of new 12mm okoume, I traced the pattern as needed, leaving an inch or so extra at the top edge for final trimming once I’d otherwise fitted the piece.  I cut out the panel and test-fit it in the boat, clamping the top edge to a straightedge to ensure it wasn’t bowed.

The fit was good and needed no changes other than to trim the top edge at the proper height, so I temporarily secured it at each end with two screws into the cleats behind.  I’d previously marked where the fasteners in the cleats were, and also marked the height of the horizontal cleat so I could easily transfer the final height to each end of the panel.

With the panel tightly secured at the ends, I ensured it was plumb in the middle (unsupported) sections and attached some small hot glue blocks inside and out to align and hold the panel properly (seen in the photos above).  Then, I removed the panel down to the bench so I could trim the top edge to the marks I’d made and prepare it for installation by epoxy-coating the end grain on the bottom edge.  To protect the front of the panel, I masked it off first.

After cleaning the faying surfaces in the boat, I applied some thickened epoxy adhesive to the hull, keeping it clear of the temporary glue blocks, and installed the panel into the adhesive and with some wood glue on the support cleats to help secure it along with the screws at each end.  I formed the epoxy into a small fillet on the inside edge of the panel and troweled any squeezeout flush on the outboard side.  I double-checked that the panel was level across the top, and later removed the masking tape from the exposed edge.

I repeated the process for the port side, first  test-fitting the 12mm panel and temporarily securing and aligning it as needed.  At the forward end, against the bulkhead, I planned eventually to incorporate a battery locker inboard towards the centerline, but for the moment I ran the panel straight across and would figure out the details of the additional storage area when the time came.

Happy with the fit, and with the panel aligned for reinstallation, I removed it to trim the top edge and epoxy-coat the faying surfaces before completing the installation as before.

By now, the epoxy on the first side had set up to the point where I could continue working without fear of upsetting anything.  From cheap pattern plywood, I made up a pattern for the center divider, a roughly triangular piece that would divide the settee locker into two sections and provide important support to the top and front panels in the process.  I roughed out the shape with some basic measurements, then test-fit the panel and scribed the lower (hull) edge to fit before transferring the pattern to a piece of the 12mm okoume for the final cut.  I left the top edge high for later marking and trimming.  This was as far as I could take this at the moment, since I needed to install tabbing on the inside of the settee front before I could install the divider panel; similarly, on the port side, though I cut out a rough pattern, I determined I couldn’t continue the layout since I’d have to first let all the wire bundles back down to the corner of the settee front, and the epoxy adhesive there was still too fresh for that.  In any event, the next steps were set up for next time.

On special request, Santa made an early stop at the shop after swinging by the hardware store and–surprise, surprise–brought me the new level I obviously sorely needed.  As it happened, this 72″ level was the perfect length for the settee berths.  I should have had this long before, but never had the need been so obvious previously.

With the new level, I quickly determined that indeed something was off–why this had been such an issue (when it didn’t seem like it should have been) remained unknown, but I found that the two horizontal cleats at the aft end were a bit low.

It was easy enough to raise up and reposition the after horizontal cleats to properly position them level with the forward set of cleats (which I also septuple-checked to ensure they were properly positioned too).  I checked the newly-positioned cleats in several places across their span on each side, and also across the boat from side to side.  This time, everything checked out the way physics and other aspects of reality required it to.

Finally satisfied with the cleats, I permanently installed them with glue and screws.

Using the long straightedge as a guide and measuring from the top of the settee down to the hull every foot or so, I made some basic measurements of the settee front to help me create a rough plywood pattern for each side.  This gave me the approximation of the curve required to match the shape of the hull.  After cutting out the rough shape from some cheap plywood, I fit each side and clamped it at the top edge to the straightedge to hold the floppy plywood securely and straight.  Then I scribed the lower edges to more exactly fit the various undulations of the hull beneath.

It took two rounds of fitting and scribing to get the patterns where they needed to be.  I made some reference marks at the vertical ends to help me cut the correct shapes there to match the bulkheads on each end (and around the tabbing at the lower ends), and some other notes to help when I transferred these patterns to the real plywood next time.

We got power back at the shop last evening around 1745, so I was happy to have a full day ahead.  To get started, I milled some support cleat stock from 4/4 poplar boards.  I like my cleats to be 1-1/2″ wide for ample screw space, split avoidance, and extra bonding area.  The 1-1/2″ width also works well when using the cleats to support a panel cutout.  Once I’d cut a number of cleats to width, I used a router and a chamfer bit to ease one edge on all the cleats, which helps avoid sharp edges in hidden spaces where one might reach into the dark someday.

Up in the boat, I installed a few temporary wire mounts so I could temporarily secure the wire bundles on each side out of the way while I worked on the settee cleats and settee fronts.  These wires would eventually be permanently secured down at the inside edge of the settee bases.

After getting set up with the layout and installation tools I’d need for the process, I started laying out the cleats to support the new settees.  I chose the settees to work on first because I was anxious to have some flat places for tool storage and to work from.  There were no significant changes planned to the basic settee height and position, but I started with fresh layout at the forward bulkhead, ensuring the cleats were level and plumb on both sides and level across the boat between each side as well.  This relatively simple process was complicated a bit by the existing bulkhead staving which, at 3/8″ thick, hung over the cleats and made it more difficult to place the level.  I secured the cleats with glue and bronze screws.  The two sections of the bulkhead were not perfectly aligned from side to side, so these factors later conspired to call some of the cleat placement into question, though ultimately the original layout turned out to be correct.

Because the old settees had not necessarily been level to begin with, and because the boat was now leveled according to some new layout marks (originally placed by the owner on the old settees, and from which I’d leveled the boat earlier in the project), and since the settee bases did not land on any flat or level surface, I had to transfer the heights of the forward cleats to the after bulkheads before I could install the cleats there.  Simple enough to do, using a long straightedge with the level atop.

But was it that simple?  I repeated this process on both sides, but the marks I was getting on the after bulkheads didn’t make sense.  This caused quite a period of frustration and double-and-triple checking everything, from the level of the boat overall to the forward cleat placement to the plumb-ness of the various bulkheads.  I’d make new marks after carefully ensuring the level was doing what it should, only to find that leveling across the boat from the after bulkheads didn’t work out with the first marks.  None of this seemed possible.  Was my level out of whack?  Was I out of whack?

By the end of the afternoon, after basically repeating my layout at the forward end to check the existing horizontal cleats and then starting with a fresh approach, I got some layout marks on the aft bulkheads that made more sense and properly aligned with each other.  The fact that the layout didn’t really match the old installation was of little worry.  However, at this point I decided to only dry-fit the cleats, without glue, so I could double check things next time with fresh eyes, and perhaps a new level (just to be sure).

As the 4th frustrating day without power got underway, and with the temperature on the cold side, it was time to hook up a temporary generator so I could run the heat in the shop and maintain the temperature at a reasonable level, and more importantly to circulate water through the in-floor piping.  The generator didn’t power the whole shop–just one outlet circuit and one lighting circuit in addition to the oil burner–and the setup wasn’t ever intended as anything other than a fail-safe, but at inception I also never expected that there would be such frequent, long outages as we seem to see now, with at least one (and often two) extended outages statewide per year.

I digress.

In the event, with the generator running the heat for several hours, I also had the opportunity to get at least something done workwise with an extension cord run to one of the powered outlets.  I had no lights in the woodshop, but plenty of natural light through the windows for what I wanted to do.   While I couldn’t do what I’d planned to do this week, which was to get started on the new settees, as I stewed over the unwanted delay, I’d come up with the idea that I could make some progress under the existing circumstances and sand the various ceiling strips (from the v-berth) and bulkhead staving (from the old nav station and galley) to prepare these pieces, which I intended to re-use, for refinishing and eventual reinstallation.  This task was something that had to be done sometime, but was also the sort of job that always seemed less important than many, so this was a good opportunity to knock it off.

The existing gloss varnish on the ceiling strips was in fair condition, but pretty tired overall, with some scuffs and scratches and a general need for refurbishment.  The backs and sides of the rough-cut strips had never been varnished, and didn’t need to be, but after sanding and before installation, I planned to apply a coat or maybe two of gloss varnish as an improved base, and then (at least according to current thoughts) a final coat of rubbed-effect varnish.  Some of the edges had some paint that had dripped down from somewhere.

There were 26 strips, each 3/8″ thick, about 2″ wide, and roughly 6′ long, in total, and I sanded them all with 220 grit and a palm sander (and by hand as needed) to clean up the surface and prepare for more varnish.  I made no attempts to strip or otherwise completely “fix” all the issues, as these strips wouldn’t be worth that sort of labor versus replacement, but that said there was no need to replace them either when a simple refinishing would make a huge difference in their appearance once reinstalled.  As a base, the existing strips were in decent shape, and I cleaned up the edges a bit as I went too.  I set all the freshly-sanded strips aside for later attention.

With more time on hand as the generator continued to run, I continued with the bundles of vertical staving  from the two after bulkheads in the main cabin (3/8″ thick teak boards cut with a v-match shiplap pattern).  I’d been careful removing these from the bulkheads, but inevitably there’d been some damage, mainly to the narrow/thin tongues on one side of the boards, as the staving had been secured with an adhesive of some sort.  There were about 30 of these pieces (mostly about 3′ long, a few longer, a few shorter), and only one had broken completely during removal.  Fortunately, there were a few extras left from the opposite sides of these bulkheads, places where new staving was unlikely to be installed going forward, so I could replace the broken piece as needed.  Sometime later, I’d have to remove the remnants of old adhesive from the back sides.

In the same way, I sanded the existing varnish on these staving pieces with 220 grit paper, including the chamfered (corresponding parts of the v-groove) edges, preparing them for new varnish to suit when the time came.  I added these to the pile of other wood awaiting varnish.

Finally, I sanded some pieces of trim I’d removed from the edges of these bulkheads, including curved pieces to fit.  I wasn’t sure if these would be re-used as is or not, but they were in good shape and I preferred not to re-make the curvy pieces if unnecessary.

With the immediate sanding work complete, I took a moment to think ahead to the new propane locker that I planned to build into the port cockpit seat.  The owner and I had agreed to build this to fit his two existing small steel tanks, which would actually make the new locker fit more easily, avoid the need to purchase an expensive horizontal tank (as originally had been planned), and, with the dual tanks, there’d be plenty of capacity–and the clear indication of usage when one tank ran dry.

With the utility estimating power restoration not until two or three days in the future, I anticipated more “project planning” time ahead, so with that in mind I laid out the two tanks on a sheet of paper to get the basic size requirements so I could figure out how to build the box and what materials I’d need.  I planned to build the box from 1/4″ sheets of fiberglass, in a design that would fit down into the locker from above with a flange to secure it on top–making it easier to install and ultimately removable for access as needed.  The basic measurements I got from this exercise would allow me to order the raw materials soon and get started on the construction whenever possible.

Following an early meeting, I had just gotten to the shop when the power went out, victim of the day’s strong winds and heavy rain.  Though this had been a threat, I’d not expected it to happen so early, but there was nothing for it but to wait it out.  In the meantime, I continued working on some figuring to determine how much hardwood (teak) to order for the new cabin trim and some other planning for the work ahead.

The damage to the grid from the windstorm appeared severe from reports through the afternoon, so it seemed likely that the power might remain out for several days, which would cause a frustrating and unplanned delay.

I made a final confirmation of the finished elevation of the new mast step before lightly sanding the new fiberglass to scuff it slightly and remove any hard edges.

There was no better time than now to go ahead and sand the upper portions of the v-berth, where I’d recently removed the ceiling planks to reveal and attend to the failing coatings beneath.

After cleaning up from the day’s sanding, I decided to lay out the mast step base fitting now while my original layout marks were still visible on the nearby structural members and before new work started possibly getting in the way.   Unwrapping the original aluminum fitting from its storage bag, I found that it was in worse condition than I’d remembered, at least after I scraped away the loose material left over from its corrosive environment.  There was also a bit of rocker in the bottom of the piece, i.e. it wouldn’t sit flat and rocked fore and aft.  While it would still be usable as is if needed, I decided to see if there was an easy replacement available and found a part number to work with, but the part seemed obsolete.  I contacted the machine shop that would be doing the new chainplates to see if they could build a replacement (yes), and as of this writing was awaiting a quote.

I started with my paper template of the original step and manipulated it this way and that according to the various measurements and layout marks.  I’d made this template directly off the old aluminum structure and had intended it to document the original, and a few things had changed.  Still, the template got me close to where I needed the step to be, but when I reviewed photos from the removal of the step in the first place, I found I’d actually used different reference points to document the base fitting itself, so I changed tactics and realigned the step according to those criteria.  This included aligning a 4′ straightedge with marks on three of the cross members beneath the cabin sole aft of the step, and also using a straightedge off the main bulkhead and head cabinetry to align the part fore and aft.  With all this, I eventually made some marks on the new structure to reposition the step, but held off permanently marking any fastener hole locations for now.

I checked the measurement between the top of the step base plate and my reference point on the mast collar above, and found it within tolerance of the original measurement, depending on where exactly I held the tape (as the mast base rocked fore and aft and affected the measurement accordingly).  The original measurement was between 67-3/4″ and 67-7/8″; now it was just over 67-3/4″.

With that complete, I moved on to some preparations in the main cabin for the new construction just ahead.  There were several small details to be dealt with before I could begin, including removing a number of old screws that still stuck out from when I’d removed old support cleats.  I removed a bit of the trim from the lower end of the starboard side of the passageway opening, as this trim had been cut to fit around the old berth fiddle, and would likely be in the way of the new work; it would be easier to replace the trim later.

The bottom edges of the staving on the main bulkhead also needed trimming, as some of the pieces on the port side extended down into a space that would, in the new construction, be part of the battery box and berth top.

I also wanted to slightly raise the bottom edge of the staving to give me a touch more room for building new.  In preparing for this cut, I found that the original ends (which had been tight against the berth tops) were far from level, especially to starboard, so I leveled both sides and across the opening as needed and made the cuts required to straighten and clean up the bottom edge of the staving.

I made some layout marks on the after bulkhead at the old nav station, leading to the quarterberth, and cut out the upper portion of the bulkhead for better access in the immediate term, and to accommodate the new galley layout in the longer term.

Finally, I removed an obsolete transducer tank from the hull in way of the port settee.  Unsure what was inside–it should have originally been filled with mineral oil or some such–I removed the top to expose within, and happily found there was nothing inside, saving me the need to pump out whatever might have been there and avoiding a mess.  A little light percussive maintenance persuaded the remnants of the tank to part ways with the hull, leaving only a slight bit of material that I’d remove next time I had a sander going.

The new fiberglass from last time required a light water wash and sanding to prepare it for the final stage of new work.  Afterwards, I dry-fit the third layer of G-10 to check its fit and check once more the measurement from the mast collar to the top of the step to ensure I had the correct clearance.  With a measurement of 68-1/2″, the top plate was right where I wanted it at this stage, with approximately 1/4″ room to spare to allow for the layers of fiberglass over the top.  I made a quick paper pattern of the area to use for cutting the new fiberglass, along with paper patterns of the forward and after faces.  The top plate fit nicely on top of the layers beneath, with just a small gap appropriate for the epoxy adhesive–no need for additional fiberglass to fill the space.

I help with the final installation stage, I prepared a “story stick” cut to 68-1/4″ long, which was the exact final measurement I wanted from the reference point on the mast collar above to the new mast step top; the stick I used during the early part of the layout had disappeared somewhere along the way.  This stick would make it easier for me to di the final measurement when the fresh glasswork was in place, as I’d not need to rest a tape measure on the wet fiberglass.  I double-checked that this worked as intended, then removed the top plate and cleaned up the whole area to prepare for final installation.

Just before final installation of the last layer of the step, I received delivery of a batch of plywood to be used for the new interior construction.

I installed the final layer of the mast step in a bed of thickened epoxy adhesive and leveled it in both directions before checking the height with my story stick.  Then I used additional epoxy to fill in and smooth over the transitions to the hull on each side, and at the vertical ends of the step to fill and clean up the edges between the three layers and where they met the hull on each side, checking the level and height measurement throughout the process.

I left this to cure for a bit while I prepared three layers of fiberglass to cover the top and secure the platform to the hull on each side; then, right after lunch, I installed the final layers of fiberglass on the top, using my story stick to confirm that they had ended up at the correct final elevation (or just a tiny touch below, as hoped).

With additional thickened epoxy, I applied fillets between the forward and aft edges of the step, and cleaned up and smoothed out various adjacent areas to prepare for the tabbing at the forward and after ends, which I then went down and cut in the shop before wetting out and installing two layers, overlapping onto the hull as far as possible, on each end of the step platform.

There’d be a bit of work to dress up the fully-glassed step in the immediate future, and some layout to prepare for reinstalling the metal step plate later, but the bulk of the work was done.  Below are some photos from earlier in the project, showing the original mast step in a couple different stages.

After a light sanding of the fillets and a final dry fit, along with a quick paper pattern to help me lay out the full fiberglass layers that would cover the top of this section and further tie it into the hull. the first section of the mast step was ready for installation.  With all surfaces appropriately prepared, I installed two layers of tabbing in epoxy resin between the vertical support and the bottom of the first section (the filleted joint), then installed the piece in the boat with epoxy adhesive on all faying surfaces, and additional tabbing (two layers) between the bottom edge of the vertical support and the hull, tying the whole structure together.  The space beneath was quite tight from the forward end in particular, but with aforethought and some careful work I got the tabbing secured as well as possible.  I couldn’t stop to take any photos of the various installation steps, but the end result had the first layer and its vertical support well-secured with epoxy and tabbing (where appropriate), and level in both directions at the intended height.

While I let the assembly cure for a bit, I prepared three layers of fiberglass to cover the top.  I’d left space for this in the design and orientation of the three layers.  Once the epoxy had set enough to continue, I wet out and installed two of the three layers, tying the top of the first piece into the hull on both sides.  To speed up curing to the green stage, I set up a couple heat lamps while I took lunch break.  This would help me get additional work done in the afternoon.

By my return, and after a visit from the canvas contractor to have a look at the cockpit and some dodger details, the fiberglass had cured enough for me to delicately continue.  First, I set the second layer lightly in place to check its fit and see how the space beneath was looking.  There was still a bit of space, so I went ahead and added the third layer of fiberglass that I’d cut with this in mind.  While that set up slightly, I prepared three new layers of full tabbing to fit the second layer, then installed the second piece in a heavy bed of epoxy adhesive (on the flat and along the hull on each side), pressing it tightly into its proper position and level in both directions.

To wrap up the work for the day, I wet out and installed the three layers of tabbing to cover the top of the second layer and secure it independently to the hull.  I left this to cure overnight, and next time I’d be able to finish up the mast step construction with the final layer and other details.

I began the week by unpacking and inventorying the new stove and sink, which had recently been delivered from Great Britain, to ensure that the items were in good shape and that everything the owner had ordered was here.  Despite some external box damage, fortunately nothing inside was harmed.

My focus for the day was the new mast step.  With the major unbuilding in the cabin complete, and awaiting new materials for the reconstruction, this was the perfect opportunity to prepare and install the new step assembly.  I’d had the raw materials on hand for a while:  three pieces of 12″ x 24″ x 1-1/2″ G-10 fiberglass, which I now had to shape to match the foam patterns I’d made several weeks before.

To transfer the basic profile from the patterns to the new material, I made cardboard patterns of each end of the three layers, which I could then trace onto the fiberglass sheets, along with a rough tracing of the fore and aft shape of the pattern.  I did the same process for all three pieces of the new step, though I’ve only illustrated the first (smallest) piece below.

With the basic shapes transferred, I started by cutting along the lines with a jigsaw with carbide saw blade set at the maximum angle to remove as much of the material as possible.  I repeated this process with all three layers to rough out the profile.

To complete the shaping, I set up a grinder and fan station near the shop door–I would have done the work outdoors but for the rain–and used a grinder and several coarse flap wheels to shape the three pieces of fiberglass to match the layout lines and the foam patterns as much as possible.

From here, it was a multi-step process involving many trips up and down the ladder into the boat with heavy G-10 panels as I made adjustments to each of the three layers, in turn, so they fit properly in the boat and at the proper heights, as well as level in both directions.  I had some layout marks from the patterning to go by.  The first piece (#3) took the most time to fit, as it ended up a bit high and I had to keep recontouring the fiberglass sheet till I finally got it down to its layout marks, and level.  Once the first section was in, the remaining two went more quickly, though each piece required several trips up and down to grind some more material from the high spots.  The spaces between each layer are intentional and designed to allow room for fiberglass tabbing on each individual layer to add to the overall strength of the assembly.

The most important thing when all was said and done was that the top layer ended up at the proper height to ultimately match exactly the height of the old mast step.  I’d built the patterns so the top layer ended up 68-1/2″ below a known point on the mast collar in the deck above, which allowed 1/4″ of space for fiberglass over the top and to fine-tune the final-final height to 68-1/4″, which was the original measurement.  I strove throughout the patterning process to ensure that if anything, the final platform ended up lower rather than higher.

To help me easily keep the pieces in alignment during installation, and to provide reference points for height and position as I went, I used a straightedge held flat to each corner of each of the three layers to mark points on the hull that I could quickly and easily use during installation and keep the lower layers where they needed to be, rather than risk any possibility of the layers “growing” as I worked up to the critical top.

When these layers were fully installed, they’d surely be strong, but as an added hedge and to help transfer the loads all the way to the bottom of the boat, I patterned, then cut to fit, a piece of 1/2″ G-10 to be installed on centerline beneath the lowest section, extending to the hull beneath.  This left ample limber space on each side.

To prepare for final installation, I had enough time left in the day to epoxy the new support to the underside of the lowest layer.  I’d install tabbing to secure the support to the bottom of the first layer before installation in the boat, then epoxy and tab the lower edge of the support to the hull as well.  My epoxy hardener was dark red after sitting in the pump tank unused for some time; apparently the welded seam on the old style tanks like mine reacts with the hardeners to cause this harmless color change.
