So what you're saying is that; in your opinion, a wide shear beam won't stop the boat's momentum as it heaves, but rather, it's stability will...
Thank's bhnautika, that's close, but I made a mistake. The dead rise angle from the bottom of the center-line to the waterline is 31deg. not...
@25deg angle of heel the designer calculated that the transverse shift of the center of buoyancy will only be 0.79'(0.24m). Hull bottom is...
Thanks, I appreciate your concise answer to the question. Is your answer based on reading of the pertinent literature on the subject, actual...
The hull is round bottom and no chine. Like with most sailboats the flam is there simply to create a beam that is wider at the shear line than it...
I use this definition: Flare= concave, Flam= convex. As relating to the outboard surface curvature of the hull from the waterline to the shear...
I am looking at a design that has a 0.72/1 ratio between the BWL and BOA. This gives a 25deg. angle of outboard convex flam from the water line...
You're right, sorry I should have mentioned the kind of vessel. In this case a monohull sailboat.
Thanks TANSL!
Remind me, is 20 and 30deg of heel or is 25 and 30deg usually used when calculating basic transverse stability at large angles of heel?
Thanks Tom, That post was very helpful. Now I'm inspired to re-read Shuttleworth's multihull stability article.
From the sound of the majority of replies, longitudinal (fore and aft) stability is a more important factor than transverse stability. Concerning...
So designers don't necessarily start with righting moment as the first factor in determining C/L - C/L beam?
Thanks Ad Hoc, Resistance being drag of wetted surface area? Structure weight Not displacement? Stability including desired righting moment? And...
Curious, what factors are taken into consideration when designing the C/L to C/L beam width of a catamaran? How are these factors plugged into...
Thanks Guys, That's the kind of info that's really useful to the consumer. I'm in the market to buy plans not design myself, but i want to be as...
Is this the wrong forum to seek info about the influence that the centers of flotation, buoyancy, and gravity have on choosing where to place the...
DCocky, what are your thoughts on the COE of rig placement and its relation to COF, COB, & COG ? The rig is well forward in the sloop i...
Rig type that i'm looking for is a sloop. Probably 3/4. Dagger boards and rudders for close upwind. Extended long bow for buoyancy, but with...
It's the pitch and trim balance of multihulls in general, but i am specifically interested in 18m long(20/1, lwl/bwl), light, fast, spartan...
