What would happen if you apply one layer of the skin on the diagonal? Not leather but thick ballistic nylon or polyester. Would it act and...
Is there an extremely rough rule of thumb about scaling scantlings ie.: A similar boat that is 3/4 the size of the one I want to build has x...
Great post. Thanks
That makes total sense. Thanks Off to research plywood :)
Actually, thinking about it, there is probably a practical limit for fabric skinned boat, where the cost of the extremely heavy/ multiple layers...
Thanks for the replies. I'll dive into the pdf this evening. Re budget use SOR etc. it is not so much a specific design as trying to learn how to...
What books would you recommend for learning to calculate scantlings for a new design. More engineering and less this is what we've always done....
Here is a video of the rig sailing: [MEDIA] There are a bunch more videos on this channel of the same or similar rigs.
What is your take of this type of sail? [IMG] Sails — Holopuni Canoes https://www.holopunicanoes.com/sails Scroll down to the Hss. [MEDIA]...
Thanks
Thanks, I was more interested in what the ideal lead would be on different points of sail, like 2% close hauled, 1% close reach, 0 beam reach,...
If you had a rig with an adjustable CE, how would you change the lead on different points of sail? i.e. More lead for running less on a beam...
From what I'm reading it seems that laminar flow or at least attached flow is best for lift but harder to maintain in real life, vortices can...
Thanks. My thinking was if you could make use of vortex lift off the wind, and therefore more forgiving sheeting like a crab claw, but use the...
BLUF: Q does/could a fractional rig use vortex lift over the mainsail? I have been reading about delta airfoils (sails and wings) and how the...
Would X-Bow type geometry work on small boats say 20-40ft monohulls or multihulls or are they more of a larger vessel thing? I tried searching...
Great reply. Thanks
You are correct, the pdf only duplicates Marchaj's results with the Santa Cruz sail not compares it to the bermuda. So would it be possible to...
Thanks so much for the input. I was wonding if the swept luff of the headsail would generate the vortex if it was at the same angle as a crab...
Sorry, I was wondering if a Bermuda rig with a similar AR to a crab claw would generate the vortex lift while still having the benefits of being a...
