Hull

Bertrams are legendary for providing the smoothest and driest ride while out in the roughest of waters. Once you experience the power of Bertram’s legendary deep-V hull as it cuts through the tough seas, we are sure you will agree. These hulls are constructed like no other. The strength and integrity of a fiberglass yacht is as dependent on the engineering as the workmanship. The high-density foam stringers in Bertrams are fully twice the size of our competitors. Extra stringers at key points for added stiffness, along with complete fiberglass flooring pans and underside deck and hull ribbing, maximize the hull integrity and minimize vibration. Instead of only screwing and caulking our hand-laid, one-piece superstructure to the hull (the standard practice), we wrap the deck-hull joint in 3/8-inch aluminum for an extraordinarily strong and rigid bond.

Advanced composite technologies are the foundation of every Bertram, which are built with the end goal to achieve offshore excellence by using composite guidelines. Hand-laid strand mat, multiple knitted fabrics and multi-directional fiber orientations create a structurally superior composite. This composite not only provides the highly desired lower center of gravity, it also aids in the long-term durability of each Bertram hull. In fact, all high-stress areas, such as the chines and keel, are overlapped and utilize several layers of unidirectional S-glass for superior stiffness and strength.

Bertram’s ultra luster exterior is achieved through the use of a time-tested high performance Armorcoat gelcoat. This exterior finish has a durability that far exceeds basic gel coats. All Bertram’s also incorporate an anti-blister protection barrier that protects the hull with advanced AME 6000 vinylester resins.
