In previous chapters enough has been told, I think, to prove that our lifeboats deserve earnest and thoughtful attention, not only as regards their work, but in reference to their details of construction. It has been said that the lifeboat possesses special qualities which distinguish it from all other boats. Chief among these are the self-righting and self-emptying principles. Stability, resulting from breadth of beam, etcetera, will do much to render a boat safe in rough seas and tempestuous weather, but when a boat has to face mighty rollers which turn it up until it stands straight on end, like a rearing horse, and even tumble it right over, or when it has to plunge into horrible maelstroms which seethe, leap, and fume in the mad contention of cross seas, no device that man has yet fallen upon will save it from turning keel up and throwing its contents into the water. Instead therefore, of attempting to build a boat which cannot upset, men have deemed it wiser to attempt the construction of one which will not remain in that position, but which will, of necessity, right itself. The end aimed at has been achieved, and the boat now in use by the Lifeboat Institution is absolutely perfect in this respect. What more could be desired in any boat than that, after being upset, it should right itself in a _few seconds_, and empty itself of water in less than one minute? A boat which does not right itself when overturned is only a lifeboat so long as it maintains its proper position on the water. Let its self-emptying and buoyant qualities be ever so good, you have only to upset it to render it no better than any other boat;--indeed, in a sense, it is worse than other boats, because it leads men to face danger which they would not dare to encounter in an ordinary boat. Doubtless, lifeboats on the non-self-righting principle possess great stability, and are seldom overturned; nevertheless they occasionally are, and with fatal results. Here is one example. In the month of January, 1865, the Liverpool lifeboat, when out on service, was upset, and seven men of her crew were drowned. This was not a self-righting boat, and it did not belong to the Lifeboat Institution, most of whose boats are now built on the self-righting principle. Moreover, the unfortunate men had not put on lifebelts. It may be added that the men who work the boats of the Institution are not allowed to go off without their cork lifebelts on.
