Underhulls can refer to any number of permanent additions to the underside of your boat hull like underwater lights or or other hardware, but the common term referrs to adding chines to a rounded bottom vessel just below the water line on either side. Many boats, especially older vessels featured rounded chines that tend to roll in heavy sea. Semi-isplacement boats and especially planing hull boats with

rounded chines can benefit even more due to added boyancy, better handeling, faster speeds, reduced planing speeds and a host of other improvements to the original hull design. In addition, underhulls can reduce roll at anchor or at the dock for improved live-aboard comfort. Cap Sante Marine uses the best quality closed cell foam for the core of its underhulls, then completely encapsulates them in fiberglass to prevent water contamination.

We have a large variety of shapes and sizes of underhull units ready to install as well as highly qualified engineers that can design custom underhull components to make the perfect improvement to your boats hull shape.
