Thursday

I spent the first part of the morning continuing and completing the core cleanout from around the edges of the two repairs as needed.  Once I was satisfied with the preparation, I completed a final cleanup of both repairs.

I used paper to make simple patterns of the areas to be recored, pressing the paper into shape in the recesses and marking along the edges with a marker.  Then, I transferred the patterns to sheets of 3/8″ balsa core and cut out the core pieces for a trial fit.   At the aft end of the cockpit around the rudderpost, I left out some of the core material so I could install solid fiberglass in these areas later for additional reinforcement and improved protection against water ingress in this area.

For the poop deck core, I omitted a large rectangular area in way of the mooring cleat; I’d fill this with solid fiberglass later.  I also masked over the cleat holes and old hawsepipe hole from beneath.  Later, once the core was in place, I planned to add a fiberglass patch beneath the hawsepipe hole, but for now I just needed to fill the hole flush during the recore.

Satisfied with the coring as cut, I began the installation by wetting out inside the deck edges with unthickened epoxy, and saturated all sides of the core pieces with epoxy.  While I let that soak, I mixed strengthened, thickened epoxy mixtures to fill all the voids beneath the deck edges, starting with the cockpit sole.  Once I’d filled all the edges and skim-coated the inner deck skin, I applied  epoxy adhesive with a notched trowel, then installed the new core, weighting it down beneath plastic sheeting. (Sorry, I have to keep moving too quickly to stop for photos during the various epoxy steps.)

I repeated the process with the poop deck core.

With the new coring in place, I could work at a more relaxed pace to prepare, fill, and, where needed, fiberglass patch some of the other holes in the cockpit, including the old shifter cable holes at the aft end, and the wiring holes in the port cockpit bulkhead.  There were still a number of small fastener holes and other preparations to do in the cockpit, but I’d get to those in due course once I had a cockpit to work in again.

Meanwhile, I continued the early outboard bracket installation.  Armed with some new information about the outboard, a Tohatsu 6 HP 4-stroke with 20″ shaft, I could get some basic dimensions (mainly the distance from the mounting bracket on the outboard to the anti-ventilation plate, which in this case was 22″) and build a simple template to show the proposed mounting in three dimensions.

I used a long level to transfer the height of the anti-ventilation plate forward to the hull so I could get a better sense of the true depth of the prop in this situation.  I couldn’t photograph that process while underway, but I put a tape mark on the hull to show the level of the plate; the prop would be a few inches below this.  I thought the prop depth looked pretty good, particularly since the actual load waterline was somewhere in the middle of the boottop as currently painted.

Satisfied with the basic position of the mount, I fine-tuned the bracket base from side to side with a level and revised my layout marks on the transom.

Thus endeth the day.

Wednesday

On the starboard poop deck, I marked off the outlines of the cut I needed to effect the core repairs, striving to stay within the boundaries of the existing nonskid pattern as much as possible and streamline the cosmetic work later.  This worked at this location because the natural edge of the core was set in substantially from the deck edge, which meant that my cutlines would still enable me to pull the core out from beneath the remaining deck edge.

Thusly marked, I made the cut and easily pulled off the top skin and most of the saturated core beneath.

Next, I spent some time removing the rest of the core and reaming out beneath the edges with a variety of tools.  After a while, it became clear I needed to extend the cut forward, since the core extended all the way to the edge of the cockpit well, beneath the traveler, and I couldn’t reach in far enough to pull out the damaged core as required.  This meant cutting into the smooth-gelcoated area of the deck aft of the traveler, but I could handle that with a change to the nonskid arrangement when I repainted later.

Once I’d removed the additional skin, I reamed out the rest of the core from the newly-widened area.  I removed two of the traveler bolts that were in the affected area so I could work without impediment.

On the port side of the poop deck, no repairs were needed, but it would make sense to at least repaint the nonskid to match the repaired starboard side, so with that in mind and tools in hand I removed the port mooring cleat from the deck as well.

Now I moved on to the cockpit sole, where I laid out similar cutlines with green tape for visibility.  The cockpit sole featured a molded gutter along the outer edges, leading to the scuppers, and the core ended within the same area, so again I left enough original top skin to allow tying in the new laminate later, but not so much that I couldn’t get beneath it to ream out the remaining core.

Working for the moment on the forward half of the cockpit–I perched on the aft part for this cut–I made the cutout and again easily lifted the skin and much of the sodden core.  Then I scraped up the remaining core bits and pulled the bulk of the old core out from beneath the deck flanges.

To remove the after half of the cockpit sole, I stood in the starboard locker and worked from there to cut out the skin and remove the core as before.  There was a solid fiberglass piece around the rudderpost, and eventually I extended the deck cut aft so I could clean out the rotted core behind this areas as well.

With most of the core mess cleaned up and out of the way, I continued work on the hidden areas beneath all the deck flanges, working to remove all the old core bits from within.  Once I was satisfied with that for now, I used a grinder to prepare the deck edges around the cockpit and poop deck repairs, removing gelcoat and slightly tapering the laminate around the perimeter to provide the necessary bonding area for the new top skin laminate.

At the same time, I prepared a few of the larger holes in the cockpit and nearby that I’d be patching later.

When vacuuming up the mess from the grinding, I’d unintentionally pulled pooled water out through the starboard cockpit seat drain and into the cockpit, and this combined with the fine grinding dust to make a sort of messy, sticky paste that got into the deck flanges and resisted immediate efforts to fully remove.  So after doing what I could, I left the cockpit area to dry out overnight so I could better finish cleaning and preparing the area.

With a bit of time left in the day, I decided to begin layout for the replacement outboard mount, which featured  a small aluminum base into which a heavier steel bracket could be mounted or easily removed for storage.  Working from the marks I’d made from the old mount, I roughed out a position for the new hardware, keeping top edge of the pad just a bit lower than the original one, which the owner had suggested was necessary to keep more of the outboard in the water.   This meant that now the top edge of the pad corresponded roughly to the second mark I’d made earlier, the lower one indicating the top of the outboard bracket itself.

Once I had enough of a mark, I drilled a hole for one temporary fastener so I could assess the position and fine-tune the layout and level of the pad once I’d confirmed everything was in the right place.  I wanted the holes for the new bracket in place before I began patching the old, as I didn’t want to lose the rough layout marks from the original mount.

Tuesday

With the departure of one boat from the shop on Monday,  I could move Arietta inside and prepare for the project ahead.  The boat was wet from recent rain, and once she was indoors I chose to work on another project in the shop and let her dry off for a day.

The known scope of work included some deck repairs in the cockpit and poop deck, plus a moderate list of smaller jobs and improvements.  To get started, I inspected the hull and documented its initial condition.  The original gelcoated surfaces were in generally good condition with a few minor stress cracks and the usual collection of dings and chips from docking and mooring accidents over the years, and the owners had indicated that the waterline as currently painted did not accurately reflect how the boat actually floated.  Assessing whether, or when, to possibly address the hull cosmetics, bootop, and waterline was part of the inspection at this time, but for the moment the only planned hull work was to remove the existing, bulky, and non-functional outboard bracket on the transom and replace it with a new, removable one the owner supplied.

The decks also featured original gelcoat and nonskid throughout, and generally were in good condition for the age.  The sidedecks featured various stress cracks extending athwartships across the decks in several areas, particularly amidships and near the rigging loads, but closer inspection and sounding revealed no noticeable problem areas within, other than obvious moisture in the deck immediately surrounding the foredeck-mounted hawsepipe.

In the cockpit, the sole was heavily cracked with obvious core damage beneath, and repair of this area was already included in the project scope.  The cockpit seats and bridgedeck appeared to be sound and would not require repairs, though with a variety of other small repairs in the cockpit, including patching numerous obsolete holes and removing additional old hardware, the project scope included refinishing the entire cockpit.

Additionally, the owner reported that the core was damaged on the starboard side of the poop deck, and inspection and sounding confirmed this.  However, the port poop deck did not have any apparent damage, so repairs would be limited to the starboard side.

In the cockpit, there were several now-obsolete holes left over from a now-removed remote engine control and its cables, and on the aft cabin bulkhead were additional unused holes, plus a pair of old wiring plugs that the owner wanted removed and repaired.  In addition, someone had secured a buss bar for the electrical system with bolts from the outside, leaving exposed screw heads, and the owner requested that I remove those and secure the buss bar in a different way from within.

The obsolete wiring plugs to port were straightforward and quick to remove, and so was the buss bar once I opened the electrical panel inside.  For now, I left the buss bar unsecured pending the completion of the repairs to the old holes in the bulkhead.

At the stern, I removed the lazarette hatch with its solar panel attached, which meant I needed to pull through the solar panel cable, which led through an old transom hole (to be patched) and into the main cabin through a hidden route.  Not knowing what was in there at the moment, I attached a messenger line from inside before pulling the cable through.  I removed the hatch partly for access, but also because the owner reported that the hatch hinges were slightly misinstalled and didn’t allow the hatch to operate properly.  I planned to fill the old holes and reinstall the hinges appropriately during the course of the project.  Later, during installation, I’d run the solar panel cable through a new waterproof deck fitting as well.

Next, I removed the old outboard bracket, which was secured with four carriage bolts through a reinforced area of the transom.  But before I removed it, I made some notes on the height of the existing bracket pad so I could properly locate the new bracket at the right height later.  For this, I used a level to transfer the height of the top edge of the old pad, plus another mark showing where the old outboard’s mounting bracket had actually been on the pad, as there was a slight discoloration and depression visible in the pad.  These two pairs of marks would help determine the location of the new bracket soon.

Continuing in the area, to prepare for the deck repairs, I removed an anchor hawse from the starboard poopdeck (not to be replaced later), a hasp from the lazarette hatch, and the starboard stern cleat.

In the cockpit, I removed all the hardware I could, including cockpit locker lid hasps and hinges, a pair of padeyes in the cockpit well, some snaps from cockpit cushions, and a pair of old winch handle holders forward.  I decided to leave the locker lid hinges in place on the decks since access was difficult to impossible, and the exisiting fasteners were extremely long and gave all indications of being recalcitrant to remove, so I thought the potential risks and time consumption far outweighed the minimal benefits of removal in this case.

Preparing for the eventual paint work, I removed the compass and sailing instruments from the forward end of the cockpit, setting them aside for later reinstallation.

Finally, I removed a wooden trim block surrounding the rudderpost, which opened up access for the upcoming repair, and, to round out the day, I collected tools and equipment so I could get started on the deck repairs next time.
