Bilge keels were fitted during a brief refit that began in October and effectively reduced the ship's roll by half.
32.
Two bilge keels were fitted ( the first used by the Royal Navy ), which significantly reduced the roll of the ships.
33.
It is tidal and dries out at low water hence it is more suitable for smaller sailing ( bilge keel ) and motor cruisers.
34.
It was a round-bilged keel ship with a round bow and stern, the latter relatively high, and with a gallery.
35.
The size of the ships was the maximum that could fit into these drydocks and something had to give : the bilge keels were omitted.
36.
Naval engineers inspected the hull, including the screws, bilge keels, and rudders, to determine the water resistance of the hull form.
37.
The ships were modified soon after entering Royal Navy service with deeper bilge keels to alleviate a propensity to roll during moderate and heavy seas.

39.
A special anechoic coating made from a mixture of gum, asbestos, and adhesives was applied to the hulls from the waterline to the bilge keel.
40.
Bilge keels are added to the outside of the land on which the boat would lie on a hard surface to stiffen it and protect it from wear.
