Rolling keel

Side wall with bilge keel and wall rail

Bilge keels are provided on both sides of a vessel permanently attached flat steel profiles, the rollers dampen (back and forth about the longitudinal axis) of the vessel. Mostly, Holland profiles welded horizontally onto the hull are used for this. The curling keels are in the position of the chine , i.e. the transition from the bottom of the ship to the side walls. They mostly run only in the area of ​​the straight central nave and thus also over the greatest width of the hull.
