Daggerboards and Centerboards require pockets for storage when not in use, which can take up a lot of space and be hard to design cabins around....
I am designing how to fit out a solar arch for a catamaran with a 16ft beam. Standard panels (for houses, industry, etc.) are around 1 meter wide....
I was going off of Sailboatdata: https://sailboatdata.com/sailboat/gemini-105m https://sailboatdata.com/sailboat/pdq-36 Looking at a PDQ 36...
It is rather hard to directly compare their drafts as per brochure, as the Gemini has centerboards and the PDQ has fixed keels: The Gemini has...
I'm having trouble understanding how the PDQ 36,which is 2ft longer and 4ft wider, managed the same 8000lbs displacement as the Gemini 105M. Is...
I should probably specify that I'm thinking of this on an existing sailing catamaran. And, if it would be better to do it but the COG, that's...
I have seen that there are aluminum extrusions available which directly work as a hydrofoil for some uses. I am wondering what would happen if I...
Thank you for the excellent responses! I just saw the Te Aihe with a square-topped jib, which seems to be used when they need less sail area....
Thank you hoytedow, however, I am not asking about square rigs, but about the shape of the fore-and-aft sails in a modern sloop. Also, if you...
Besides the convenience of fitting and filling within the mast and stay(s) without interfering, why are most fore-and-aft sails triangular?...
GggGuest, Is the above effect, that masts work as airfoils, perhaps one of the effects you are suggesting was missed by the first exciting uses...
Will, That's a good reminder that, unless it is perfectly round, we should consider the mast as an airfoil itself. If you have a rotating...
Brian, It's kinda weird for me seeing finding the latest exchange. Rather than finding it because it is an active thread, I found it in a search...
