Looked today ( Boat Choices)

Ok, I got intrigued and ran some numbers applying your above methodology to three other boats (I'm in accounting, numbers interest me): Pacific Seacraft 37 .38 Tayana 37 .30 (!!) Cabo Rico 37 .37 Now, I am not a naval architect, but the people who designed the above (well-respected) sea-going yachts are, and their numbers prompt me to ask what you base your 40% number on. I'm not calling your assertion questionable, I just want to know what I am missing here- help me out. There are a lot of numbers and B/D is probably going to be lower on heavy displacement boats - like the ones you are looking at. More useful will probably be Displacment to Waterline Length, Motion Comfort Ratio, and Capsize Ratio. Looking at my notes, a Catalina 30 we looked at had a B/D of .41, a D/Wl of 291.4, a Comfort ratio of 24.8, and a Capsize ratio of 1.99. The Crealock 37 we looked at was .383, 344, 34.3, and 1.7 respectivly. It's important to remember that these numbers will only give you a suggestion of how a boat will perform. In reality there are a lot of factors that go into performance that these numbers can't account for. Cindy -- the return email is a spam trap send legit emails to cindy_at_ballreich_dot_net |
