Thank you for a tool of great help. It is the best of its kind (and the only one
As I am the total noob at designing boats, and probably one of the most ignorant in this forum, I have a few questions. I hope you or anybody else who understands and/or is wise will have the time and patience and willingness to answer. The questions are about your fine cat starter.
transverse stability: what is a good value for BMtrans?
longitudinal stability: what is a good value for BMlong?
EU design category and EU size factor: what are these used for?
height of lateral area: what is it? I saw in your "manual" that it is below waterline, but to where?
height of foretriangle - the height of center of effort from waterline? Is it for fractional rigging?
height of mainsail - the height of center of effort from waterline?
design righting moment - how does this help me?
limiting righting moment - how does this help me?
(elliptic side profile) - are numbers different if the "plan" (profile) is rectangular?
sail area / displacement - how does this help me?
thanx in advance
