Welcome to Compu-Spec, with data on over 5,000 keelboats to help you to select hardware for your boat.

Compu-Spec knows the loads on your boat and the appropriate hardware for it.

Compu-Spec will ask you some simple questions to determine what hardware is on your boat and how it is installed, then will present hardware recommendations.
