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.
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 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.

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.
I came up with an upgraded view of the very successful Alii Nui 65 daycharter cat, for an upscale market. Hydrostatics are exactly the same so should be only a plans extension. It keeps the row of seats all along the cabin side. Slightly smaller motor and clip the fin keel
This little unit worked so well that Kauai needs another. Submitted soon.
I’m still trying to decide if its worth it or not. Last year was extremely valuable in both information and networking. And the exhibiters were amazing. Will there be that much more this year new?
Only a couple of the classes look like they will have something that I don’t already know.
Steve D’Antonio and Belle Blanding will be there; always informative. I see there is a seminar or infusion repair. They should have asked Ollie with his secondary and tertiary infusion when the primary failed. Missing the early bird price today. Still not sure.
And oddly, SNAME is having an expo in Tacoma at the same time.

I was in Europe, then work was piling up so quickly that I put this off. And the phone won’t let me onto this site to add and edit. I have been doing things on the Facebook Multihulldesigns page as it is instant on the phone. Catching up here a bit now.
On the Seine in Paris. trimaran in the front and catamaran seen aft.
