[Public-list] Center of Buoyancy

[Robert Kirk]

Mike & Roger... Jack Horner, surveyor & former A30 owner gave a winter 
seminar a few years ago where he passed out a set of linbes, stability 
calculations, & polar plot  for the A30. I don't know where he got them, 
but he's also a marine archetect  so I guess he made them himself. (I can 
fax you a set of the handouts if you'd like. Anyway, he shows the Lateral 
Center of Buoyancy 16.1 feet aft of the bow.

For info, he also calculates:

Max GZ          1.352 ft @ 60 degrees
Prismatic Coeff 395/384
SA/Disp         15.2/15.4
Beam/length     .29
Ballast/disp    .37/.38
Comfort ratio   .32/.31
Pounds/in immer 676
Moment to trim 1deg 775lbs
Righting Mom @1deg 405 lbs
Wetted Sfc area 204 Sq ft

Hope those numbers mean something to you.
