The self-emptying principle was accomplished by the introduction of six self-acting valves into the bottom of the boat, through which the water, when shipped, ran back into the sea! When we first heard of this we were puzzled, reader, as doubtless you are, for it occurred to us that any hole made in a boat's bottom would inevitably let water in instead of out!
A lifeboat that is to say, the lifeboat of the present time differs from all other boats in four particulars. It is almost indestructible; it is insubmergible; it is self-righting; it is self-emptying. In other words, it can hardly be destroyed; it cannot be sunk; it rights itself if upset; it empties itself if filled.
Wherein does it differ from other boats?" are questions sometimes put. Let us attempt a brief reply. A lifeboat that is to say, the present lifeboat differs from all other boats in four particulars: 1. It is almost indestructible. 2. It is insubmergible. 3. It is self-righting. 4. It is self-emptying.
Being full of water, the lifeboat would be comparatively useless but for its fourth quality that of self-emptying. This is accomplished by means of six large holes which run through the floor and bottom of the boat. The floor referred to is air-tight, and is so placed that when fully manned and loaded with passengers it is a very little above the level of the sea.
