Cats that haven't got enough underwing clearance slam weather they lashed or solid. I have a similar designed cat to a Wharram and it is solid with 3 beams that are bigger than on the Wharrams and solidly connected right into the bottom of the hull. My boat is 42 feet long with 25 feet beam but it has 1 meter of clearance and it has never slammed. I live and sail on that boat for 27years. The boat is about 36 years old and there is no stress cracking anywhere because it is very strongly build. However, the lashings on Wharrams take some of the shock out of it when say, broad reaching. My boat has a bit of a jerking motion that the Wharrams don't have, but I also have a wider beam, which adds to it. I have the benefit of a bridgedeck cabin and access into the hulls from that cabin, but it is a trade off. All the best with your project. I do like the Wharram designs, they're great boats.
Slamming , like you say is created by not enough clearance under the Bridgedeck ,Wharrams have miles of clearance.The movement , as slight as it is due to lash I go has nothing to do with slamming I believe , lashings seem like a pain , if I could glass the beams on or bolt with rubber as you have I would be happier. I was fortunate enough to meet Tom Hembroff who along with his brother lashed the first Ariki Beams together when they had to …..thanks for sharing ,interesting stuff.
Thanks for checking out the videos. I hope to take advantage of some of that space and will actually drop my Center deck a bit. Not enough to bother. 🤙🏼
great work! I love your yurt! and your workshop pretty well set up! It's so interesting to see how designs evolve. I think the lashed beams are also a great fashion statement!
Aye, the lashed beams are brilliant looking. I met a guy who’d arrived here from the Caribbean, said his lashing were quite loud. I’d not heard that before.
My experience the lashings can be loud and annoying. To tighten them is a very big job and the flexing will make retightening regularly. I solved that by mounting strong belttighteners on top of the lashings so I can put the tension up by one hand in two seconds. The kind of belt-tighteners as used on trucks and in the carworkshops. They don’t cost much and give a quick fix.
Also: the flex of the structure needs the pods and everything that is build on the structure to be able to move and twist as well. So when you wondered why the pods and the cabin were not bolted to the beams or where you wondered why the roofcabin was held with only two bolts to prevent blowing off. ........
Yes, that makes sense. And for the average guy out there, and in me, that’s a surprise I’d not realised, thus I’m exploring the design as I go and discovering these things 🤩 I’ll mention this point when I work on the new pods. Thanks for your comments!🙌

Glad you have found the answer now.

Awesome work!
Thanks my friend 😎🤙🏼
