I like to finish things off as I have done here with a wedge or two that has been lying around the garage. Eventually this will be 3D-printed... but not in wood.
There's an argument for extending the size of these at the prow in order to provide buoyancy at the forward end; they would not need much material at all to do so, given the leverage at that distance from the centres of buoyancy and gravity.
We're talking moment arms here, aren't we, beloved by both aviators and mariners?
