I think that I have tried every kind of weatherstripping to seal door closures or wet hatches. This model, called Rubber seal, ribbed, seems to be the best I have ever tried. All are adhesive backed. The ribs allow one part to deflect, without distorting the whole seal like a square section would. The black one is 3/8″ thick, from Grainger. https://www.grainger.com/product/TRIM-LOK-INC-Rubber-Seal-10D149
The white one is at Home Depot. They don’t carry black. I think is 5/16″ thick.
Grit. Voyaging under power on a beautiful day. Amazing finish inside and out.
link fixed now I think.

Paul started with the KHSD 45 cruising cat plans, but wanted some changes. I did a composite bow tube design for him.
I don’t recall being told it would be forward cockpit. The helm is indoors, which is always good.
I recently had to review a chainplate on one of my COI cats and send a note to the USCG.
I see from the X-Ray report that the Aolani chainplates were not steel, but composite as I thought they were.
These composite plates are immune to corrosion, unlike metal ones.
I assume the builder used my layup schedule as I have sent earlier. I see no reason to doubt that.
They are easy for the builders to build in a huge safety factor.
Instead of being fastened onto a hull, these synergistically combine to both strengthen the hull and the chainplate.
Unlike the metal plates, these have some resiliency so make all the parts longer lived.
Any delta in the parts from the loads would show up immediately and early by cracks in the paint. Unlike metal plates which usually are not painted.
Attached find a picture of one of my other catamaran designs with composite chainplates. Note that he lifts his entire vessel with only the three chainplate locations.
I got to visit my 49′ daycharter cat in Fort Lauderdale . Always one of my favorites. Met captain Jason.
Built mid 90’s by legendary builder, Andre Cocquyt as a composites class project. Students included IBEX presenter, Belle, Blanding.
Still looks good and can be built remotely from assembly.

I love this thread.
somebody actually has informed opinions on multihulls. and again, I utterly disagree that we should not comment on what we see.
Found by Phil who I have great respect for.

Another source for a whole armload of composite supplies and prices not too bad. No knitted fabrics though.
In the west of the US only.

A screen grab of an upgrade to the 36′ daycharter cat. Foam/glass with flat bagging table used for most of it. Full standing headroom in hulls, and a bit more elbow room. But still a skinny, easily driven waterplane.
24 passenger typically, though JS got 49 pax on his.
It looks surprisingly better to me than I imagined, despite having seen it in 3D renderings and in the shop.
More activity in Lake Chelan.
