new 31 Tri at Wooden Boat Festival.

I can’t believe that I have been lured into designing a new millennium searunner. A custom design where the design requirements eventually became center cockpit over any others. I, and most other designers, rejected center cockpit as it takes up the biggest part of an already too skinny main hull. Ply/epoxy. For the wooden boat festival.
Added more items, lowered the boom, photovoltaic, and added people. And the in position. Customer has been friend for 30 years. I have not even thought about plans. Just enough for his wooden boat festival presentation. I just noticed that the seastays vanished in this Luxology rendering method. They are there.

Plywood flat panel construction main with core as needed.  Amas in CM developed plywood.  Amas and tubes slide in for mooring in a marina.

Explaining the Sarabi Anchor System

Barry showed this to us several years ago. It keeps the down load off of the bow tube, and snugs the anchor back into or near the main beam.  A big roller lives at the end of the bridle, which the anchor line and chain run through.

The live picture is of the Sarabi installation. They used it for years crossing the Pacific. Salty Cat, a KHSD 45 has the same system.

Alii Nui Proposal

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

IBEX 2019

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.

Back, Again

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.

Explorers Help

From 4 years ago a memory, but so cool. The KHSD 56′ catamaran to the rescue.
“Tanks for Vanuatu! Above & Beyond the Call of Duty.

When the crew of Sea Mercy’s Disaster Relief vessel “Lil Explorers” (Courage and Shannon) got word that the people living on two of the remote islands in Vanuatu were in grave danger and at risk (their water catchment containers had been destroyed by Cyclone Pam), they made a decision to find a way to help. Where everyone said it could not be done, they said they would find a way to help. The question was how to get the water tanks on their vessel and secure them enough to make the 80 mile sail to the devastated remote villages in order to deliver them? These pictures show that where there is a will there is always a way. Be warned, these pictures are not recommended to be viewed by the “faint of heart” sailors.

The good news is that containers (water tanks) made it safely, were offloaded safely (floated in), the remote island people were so grateful, and Lil Explorers and her crew came away unscathed and as hero’s. We’ll post the full story (along with offloading pictures and video) when they return to Port Vila and have internet again.

Thanks Lil Explorers!”No photo description available.

Harken Shock 2

Almost done with setting up the 22mm mainsheet car system.
After learning that the Harken end blocks would be around $200 each after tax, I resolved to make my own.
I laminated then trimmed some 5mm thick  ones of scrap carbon fiber. The end blocks attached by soft solution.
One result of a gifted car was that the pins were too bent to remove for attaching new turning blocks. Nobody stocks the 5/32″ pins needed. They said Harken would need 5 weeks and much money to replace. I am using stainless bolts from Stoneway Hardware.  Ends not fastened to the track in this picture.

Harken Shock

 For decades Harken has been my go-to deck hardware company. I was recently gifted a Harken 22mm car and bought track for it, for my 12′ trimaran.
As noted in earlier post, the cost for the track end blocks shocked me.
Today I bought these beautiful Lewmar blocks for $14 each at Fisheries. I did lam up some ends for these blocks which I will paint and post next week.

New Eco Foam

I’m always on the lookout for new foam core products that can reduce the hurt to the wallet or the environment, or both. https://newatlas.com/cellulose-foam-insulation/59654/?utm_medium=email&utm_campaign=2019-05-14%20083526%20Other%20Daily%20Basic%202019-05-14%20083930%20Eco-friendly%20foam%20outperforms%20the%20real%20thing&utm_content=2019-05-14%20083526%20Other%20Daily%20Basic%202019-05-14%20083930%20Eco-friendly%20foam%20outperforms%20the%20real%20thing+CID_857d128ac851e6afd69c585a1ad7bc0b&utm_source=Campaign%20Monitor&utm_term=Read%20more

But bugs me when they have odd anecdotal measures of strength or insulation values, but no actual numbers.
