Answer by  worker7922 (25)

The maximum hull speed of a displacement vessel is determined by a formula using the length of the waterline (LWL). The LWL is taken and plugged into the formula (1. 34 x (lwl)^1/2). This should give the maximum sailing speed of a displacement vessel. Planing hulls are not constrained by the limits of the given vessel's waterline length.

You should clean the area with acetone, then the get some 120 grt sand paper. Mix some gel coat and apply that to the holes with a patching trowel. Cover gel coat with wax paper. Remove wax paper when dry, then apply a coat of paste wax.
