Hey Rob ,
I hear you on the holes in hull and keeping it as simple as
possible. The drag wouldn't bother me to much but just the thought
of having that lower brace getting bombarded in any wind over 15
knots or lumpy seas. I have been experimenting with rudders hung on
beams with models have a few funky design which led me to tring
manipulation of hull wave.
Heeling and sitting low. All in favor of load windage. But as you
said wind ward hull draws 12 '' and leeward hull looked to be riding
pretty low with the small amout of heel. I'm wonder was the boat
loaded or light for the short trip?
I Have seen those aluminum power cats with their no rocker and sheer
lov'em . Havn't seen the A class lately.
Whens the 60' live aboard for a family of 4 coming out with salon?
Keep the video coming.
