RE: [PSUBS-MAILIST] K Boat Builders Question.

["Daniel Lance" <lanceind@earthlink.net>]

James,
 The bevel provides a smooth reduction " in section "  . An abrupt
transition from 1/4" thick to 3/4" thick would result in a stress raiser.
Go with the bevel . Capt. Kittredge did his homework. The K-Boats are very
well designed.
