: Yes, it looks like I was a bit wrong there. I took the wetted
: surface area of the black pearl on Bjorn's site and did a rough
: doubling. Checking the Petrel details tab on Nick's site shows
: 4.3 m^2. I'm guessing the Petrel and Black Pearl will be similar
: in surface area.
Wetted surface area is just the bottom 4 inches or so--that part of the boat which is BELOW the waterline at the design displacement.
You need to figure the entire boat, which could be about 3 to 4 times that, or more. The deck alone has got as much or more surface area than the wetted area, and then you need to figure in the sidewalls.
