: I just designed and built a SOF kayak and it is very tippy, and very fast.
: Mine is a 20 inch beam. How wide are racing kayaks?

I'm building a racing kayak too. Anyway, an olympic racer can be a maximum length of 520 cm (17 feet). The minimum weight of 12 kg or 26.4 lbs. There WAS a rule that the boat width had to be 10% of the length (which would be about 20 1/4 inches for a 17 footer, however it was eliminated. The reason being, manufacturers were making boats that were real narrow in the water, then bypassing the rule by making their decks have "wings" like a 1950-something Cadillac -thus the rule didn't really effect the performance of the boats, so they did away with it. For more info, go to www.usacanoekayak.org/ -click on "sprint" and then "boat description". I (actually we) would like to see a picture of your boat!
