The great ship, with bilge keels, was as steady as a rock.

Bilge keels were fitted in 1894 which improved her maneouverability.

Both completed ships rolled badly until fitted with bilge keels.

Bilge keels increase hydrodynamic resistance to rolling, making the ship roll less.

Bilge keels can also be used in conjunction with other roll damping devices.

She rolled badly until fitted with a bilge keel.

The bilge keels were lengthened and made deeper (a process that took a minimum of three weeks).

Then she pressed her ear against the damp, rusting metal of the bilge keel.

Roll damping by bilge keels of sufficient size will reduce the hazard.

The bilge keels were removed to facilitate damage-free passage through ice.

Four bilge keels were fitted to improve stability.

They were fitted with large bilge keels and with anti-rolling tanks.

A bilge keel is constructed from flat plate so as to present a sharp obstruction to roll motion.

Bilge keels are often fitted to smaller sailing yachts.

Black Jack is steel-hulled with wooden bilge keels.

The Germans curbed this problem by retrofitting larger bilge keels, which also cut speed.

Eighty Pioneers were completed most with bilge keels but also fin and centreboard.
