Abstract
A bilge keel design for improved ship roll damping performance. The bilge keel has a porous region substantially at a forward end, and is designed to alleviate and mitigate added drag from flow misalignment due to scale effects and variation in vessel speed and loading conditions. The bilge keel design is use on both port and starboard sides of the vessel hull.
