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
Looks to me, you need to study:
1. A book of naval architeture
2. A book of boat design (like Larsson & Eliasson: Principles of Yacht Design)
3. A book of sailing catamarans (like Harvey: Multihulls for Cruising and Racing)
4. EU:s Recreational Craft Directive
There are no shortcuts, really. Some doubts can arise if one states the japanese saw an excellent tool, but has probably newer sawn the wood. Still, happy studying!
Only shared knowledge can grow.
Home Depot and Lowe's sell them in the U.S., so your local hardware store probably sells them, also. They cut on the pull, not the push, are very thin and very sharp. Check out homedepot.com
Whoa! I didn't realize it can be that expensive... Thanx hoytedow!!!
I think I will stick with the Finnish saw for now. It cuts all North American hardwood like a hot knife cuts butter.
