Abstract
A multi-hulled vessel for upward ice-breaking is disclosed. The vessel has side hulls that are at least partially submerged while the vessel is underway. The side hulls each have a ridge on their upper surface. To break through ice at sea, the side hulls are positioned under the ice and the trim is adjusted for an upward trim angle. As the vessel moves forward, the ice is lifted and force concentrates along the ridge on the side hulls. The ice breaks along this force concentration, aided by the weight of the ice itself.
