I have an Obrien board with retractable centerboard, about 12 feet long.
Can you tell me some history on the board, date of manufacture, ? liters,
best size sails to use, what the core is made of, what are best conditions
to use in, etc. I have had some great sailing on it! I also snapped the
centerboard but was able to replace it with a perfectly fitting Allgaier
daggerboard from THE HOUSE in MN.
