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.

Not many dinghies like this exist and I know of only one other self-built catamaran dinghy, and that one was also 10 feet long, but not of the same design. This design starts out like a flattie rowboat hull, then gets a foam bottom which is shaped with a hot wire, then is glassed over the foam, and then gets another hull built the same way, plus a crossdeck structure.
.
This first photo is Richard setting up the hullsides, bulkheads, and a temporary bulkhead, prior to bonding them all together (except the temporary one) with epoxy fillets.
.
The final weight of this boat is supposed to be less than 100 lbs. I expect it will come in under that weight because my outrigger canoes all weighed about 50 lbs (main hull) and that was 18 feet, about twice the catamaran, and made of heavier weight plywood (5 mm). This catamaran is made primarily of 4 mm. The extra glassed on bottom will add some weight, but not a whole lot.
.
Apparently this design can be paddled, rowed, or sailed.
