Good to know about creating a fabric "pop-top for a Cat25 that doesn't have the factory pop-top. I never would have thought of that. So I can have 6'-4" headroom in that part of the cabin! Nice.
Mikem, being curious about all things, why should one not sail with the pop-top up?
Noodat Lady, I love that pic of Greta!
I just began reading Ted Brewer Explains Sailboat Design. He includes an interesting tradeoff chart for different types of sailboats (see attachment). Since I am searching for a trailer sailer, I'd like to sacrifice some comfort for speed, but that's probably asking too much.
I'm curious about sailboatdata's inclusion of S# in their Sailboat Calculations. Their definition:
S# first appeared (that we know of) in TellTales, April 1988, “On a Scale of One to Ten” by A.P. Brooks . The equation incorporates SA/Disp (100% fore triangle) and Disp/length ratios to create a guide to probable boat performance vs. other boats of comparable size. For boats of the same length, generally the higher the S#, the lower the PHRF.
Under 2 - Slow, under powered.
2-3 - Cruiser
3-5 - Racer Cruiser
5+ - Fast/Racing
But what is the equation? I tried dividing Disp./Len by SA/Disp, and did not get the same number, Anyone know?
