DC, many thanks for your links, that is exactly what i was looking for! I did not see with a quick read , but i will for now imagine that they are...
Indeed, which is why i was careful to precede my analysis with the word "hydrostatic" I would say that a full dynamic mathematical analysis,...
Ok yes. Got it. Seems like that is certainly a good enough number for big boats. Espeially when one thinks that a lot of people will be somewhat...
TANSL wrote above that «The cog of a seated person is between 5 and 10 cm above the seat» I would like to know how TANSL arrived at this If...
Phil, thanks for the link, that is a rather interesting design, although it is obviously severely distorted to conform to a minimum beam racing...
Guys, we're drifting off topic. Yes i know these compromises are never all that satisfactory, and no, if someone wants a much wider boat, there's...
«For the record, some of us still paddle » kkk yeah i know , just being a bit facetious. No, it is primarily a paddle boat that , just knowing...

One approach that seems to be possibly realistic is to place each human's CG rigidly at the CL, but instead of around the navel, put it actually...
In the general case where all the masses in a boat are in rigid positions w.r.t. the whole boat, the condition for positive small angle stability...
Just thought a little image dump here could be entertaining. Hopefully it's not old news..
Rig image without spinaker or flying jib. Cheers
As i had said here is the mast etc. This is a work in progress ie unfinished. I say this preempting people getting over-excited as too often...
Thanks Eric for all that info! Thanks Olav for the picture. Baigent, yes, good point. So, in conclusion; Clearly there is no problem in...
Par ; agree that this sounds like the best approach, however there has to be some provision for a little "swing" in the mast which could...
