8' from the LWL, probably 7' 10" /7' 11" in real life. Lines drawings say 7'11" but it's 8 if I put a lot of stuff on.



Not quite sure of the exact weight so calculated to be somewhere...

Aah, now I understand- ours is a CCA boat (she's skinny all over but draws 8'). No hobbyhorsing but she's a wet ride to windward.

Agree with you on 1 2 and 3 but I don't see how fine ends promote hobby horsing (bluff ends would be worse). A (fairly) narrow beam with a good deal of depth goes fine downwind.:thumb:

That's probably where the idea that heavy= pig comes from. Production boat designers think that most people want beam, not depth. (rightly or wrongly)

having a larger lateral plane for the keel can be pretty independent of displacement.

Not necessarily as a good deal of the righting moment at a given angle of heel comes from form. There's not enough info in SA/Disp or % ballast to get there. Note centerboarders for example.

It'll have more momentum so it'll accelerate and decelerate slower. It shouldn't have an effect on final speed if the SA/disp is the same.

Shape always matters, even in cruising boats. (it's just...

True, but by itself, having high displacement doesn't necessarily mean the boat is a dog in light airs. SA/Disp is a better gauge of that.

Fixed it for you. ;)

I think there is too much fixation on "light air performance" and "windward performance". Look, unless you're racing around the buoys an extra couple of degrees of pointing...

Looking at the ratios is the first step. You should also look at the beam and hull form. I'd guess from the numbers that the heavier boat has easier bilges (less pounding).
