reach the stoppers. The cradles remain at rest on the stoppers and the
boat comes automatically alongside the embarkation deck, irrespective
of list. When the life-boat has its full complement on board, the brake
lever is again lifted and the boat continues to the water. The hoisting
of the boats is effected by means of the winch, and in the case of the
larger class of boats electric hoisting power winches are supplied for
lifting the boats up the ship's side to the stowed position In tests
carried out under inspection of Board of Trade officers, the time occupied
from the releasing of the gripes until the boats reached the water (a
distance of 40 feet) varied between 20 and 28 seconds, the whole
operation being carried out by one man.
