Dinghy Skeg
I was suffering with what seemed like a cold and also had allergy symptoms. I awoke and felt fine. The green pollen that was coating everything was gone. Maybe it will return.

Clammy Hands
Items came in from TEMU, the Chinese cut rate retailer. One was a nice little drone that cost about twelve and a half dollars. It looked like an easy thing to play with while I coughed and sneezed. I was fighting a summer cold, even though it is not summer elsewhere, it seems like it here. A nice [...]

Sun Doggie
After laminating the cedar strips onto the gunwales of the dinghy I found the screws I used wouldn’t come out. The epoxy had seized them. The screw heads were stripped so I cut a straight slot in the heads with the cut off wheel. The cedar smoked when the screw heads got red hot. I could remove [...]

Just Add Water
The rainy weekend started off with overcast and fog but no rain. It looked like I might be able to get something done on the D4 dinghy. I wanted to change the bow seat which is really the bow deck. The sailing option uses the deck to hold the freestanding mast. I didn’t like how the deck looked, [...]

D4 Dinghy Alternative Seats
The rain event was more wind than rain, strong winds with gusts up to 44 mph. We drove into town to see what the harbor was like. There was a small sailboat that had dragged anchor and was sitting close to shore. The tide was out. We left and played with Bleu at Notter’s Pond.

D4 Inside Seams
Day two of the dinghy build started out with me finishing wiring the hull bottoms together on the centerline of the bottom panels. This was much easier than the wiring of the chine edges of the bottom panels and the side panels.
Tortured Ply Main Hull Pt. XV
.
The gunwales are kind of floppy. Stiffening them will stiffen the hull. Inwales will stiffen the gunwales. They are lightened by blocking them inboard away from the gunwales. This is called a ladder inwale. It would be nice to round the edges of the gunwales and inwales. The trimmer router would do a good job, but it can't get everywhere, and not all the edges have to be rounded. We will have to dry assemble, mark, and then round off.
.
A yacht designer named Ralph Munro developed proas on Biscayne Bay around 1900 or so. He stiffened the gunwales by adding a narrow side deck with coaming on the lee hull side, and a shelf outboard of the gunwale on the windward side. On the windward side, the shelf would deflect spray coming off the hull or coming up from the outrigger. On the lee side, the narrow side deck would help add buoyancy if the proa was knocked down in a gust.
.
I was told what I was calling a ladder inwale is just an inwale.
.
We had a rain event, so work had to stop with the inwales and blocks cut, but not yet marked. The next day they were marked as to where the blocks would go.
.
In the tortured ply hull a spot near the bows was kind of dished in, so spacers were glued in to keep the hull shape fair and concave.
.
The flat polyproplene webbing for the jack line for Kaimu came in and was delivered to the boat at anchor. We will be docking in a couple of weeks to provision for the cruise to the Florida Keys.
.
Another rain delay came through and everything was covered again.
.
Deck beams for the ends of the tortured ply hull were cut and test fit. I'm hoping they will prevent the cambered deck from dishing, keep a fair curve. The big glue up took place with the 4 inwale stringers and 56 little wooden blocks. The process was tedious but simple. Air nail the inwale stringer to the block while holding it in position against the inside edge of the gunwale, then do the next block, etc. The deck beams were also glued in place. The wave piercer hull is now almost complete, just needing crossbeam saddles and more epoxy and paint. The tortured ply hull needs a cockpit floor and decks along with the beam saddles.
