I''m trying to obtain assistance in replacing my dagger baord for my sailboat. My boat was blown off it mooring last summer during a storm and I found it upside down. Once righted, the only thing wrong was the missing dagger board. It was steel and went to the bottom of the lake. The boat is a sidewinder by the MFG Boat Co. from Union City, PA, Dewsigned by mac alpine downie/Gibbs. The only number i could locate was 897. Anyone out there have nformation on getting information on the dimentsions of the dagger board so I can reproduce it? Thanks.
