My father and I race small 10-12 foot boats with 30hp outboards, with speeds in the high 60's. There are several classes that will be racing as well, that are faster. Its a two day event (sat and sun) and is open to the public, free of charge.
There will also be drag racing. The races usually start around noon and go until 5. If anyone wants more info pm or call me, (207-615-3124).
you can see a few pics of my racing on my facebook or these pics taken by our photographer:
