Bulbous bow and course stability in explorer yachts

The bulbous bow plays an essential role in the design of Bering trawlers. It reduces pitching in heavy seas and, in conjunction with the forward watertight bulkhead, creates a collision space that provides an extra measure of safety. Bering's custom bead bow with integrated bow thruster has a sharper vertical approach than most bead bows. This design aims not only to guide the bow wave lower at the waterline, but also to minimize the pressure coefficient along the bow. In addition, the bow is ballasted to reduce pitching in heavy seas. Another advantage is that it serves as a collision space in case the ship collides with a floating or submerged object.

Two massive rudder fins act as passive stabilizers, reducing roll, increasing course stability and protecting the propellers and rudders. They also allow the trawler to remain upright when stranded, allowing the Bering to rest on its hull when needed for hull inspections or simply for bottom cleaning.

The shafts and propellers are housed in skegs, which provide increased directional stability and improve the yachts' course keeping should it ever be necessary to sail with only one engine.
