The keel is strong enough to support the weight of the boat out of water when drying out or in the event one goes aground. The centerboard version has a shaped board with the pennant attached above the water line. When the board is up it fits into a mated slot thus virtually eliminating turbulence. The Nimble 30 is of sufficient size to allow documentation. The advantages of documentation are varied but perhaps the most relevant is that it allows for financing of the boat by out of state lending institutions and for a longer period of time than the local bank.
Structual bulkheads are glassed and mechanically fastened to the hull.
