ON SEAGOING BOATS
"The sea and the wind are not our enemies. They seldom destroy our vessels without our connivance. It is our own folly, neglect or carelessness, that opens the way for the attack."
ON SEAGOING BOATS
The first and absolute necessity of a seagoing boat is freeboard; the second is a complete deck and water-tight openings. Given these two things and you have an almost safe craft. There is no question of capsizing a well-designed yacht of to-day by power of the wind. Our outside ballasted boats cannot be kept wrong side up, so long as the water is kept out of them. They may be hove down on their sides and fill and sink, but they cannot be turned completely over so long as they retain their buoyancy. I have been in one of them, a boat carrying only about half the usual weight of lead for a vessel of her size, that was laid on her side in a squall with both mainsail and jib in the water; she remained in this position for nearly two minutes, and then righted when the force of the squall was spent. Her lead kept her from turning right over, and her large freeboard kept her from edging down. She simply made a bottom of her side and floated on it. That is one advantage of freeboard. Had she been a narrow-sided boat she would have been forced between the pressure of lead and wind deeper into the water, but as it was her displacement, owing to the bearing up of the sail and mast, was probably less when in that position than when standing upright.
Again, freeboard increases the range of heel. This is of enormous advantage when sailing in a sea way with a strong breeze. The tripping power of the wave is exhausted before the rail is brought down, and the boat not receiving a load of water on her lee deck rights so much quicker. A low-sided boat when canted by a beam sea edges her rail under and shovels the water up on her deck as she recovers. For this reason seagoing craft should have their upper freeboard slightly tumbled home. Bulwarks and high rails are bad things, and combings should be kept well inboard, while raised cabin houses if fitted should not be carried too close to the waterways. Rails and bulwarks as far aft as the rigging can be raised to an advantage, as they prevent the water from coming in and not passing out. Water in breaking on board will always follow along anything like the side of a house, and when reaching a break spread in. This is how cockpits are so easily filled. The height is suddenly cut down from house to combing, and the sea having become crowded up to the height of the house in its passage aft, when it comes to the low place rushes into the cockpit. If the combing is carried up to the height of the house the water will pass along and go out over the stern.
Ballasted boats should never go into rough water unless they have water-tight cockpits and water-tight companions and openings. But a water-tight cockpit, unless it is well-scuppered and really self-bailing, is of little use. In eight out of ten small yachts the cockpits are not, although they pretend to be, self-bailing. They will bail perfectly when at anchor. In order to bail quickly the floor must be at least ten inches above the load water line. Here again freeboard comes in. Again, the placing of the scuppers in the forward end of the cockpit and their outboard openings under the bilge is decidedly wrong. In the first place it keeps the water at all times in the forward end of the standing room against the cabin, just where you move about; in the second every drop that goes out through the lee pipe has to force its way against a pressure. This pressure is also constantly driving the water up and into the boat. The place for the scuppers is aft with the openings under the stern. Here there is constant suction so long as the boat is moving ahead, no matter to which side or how far she heels. Again, if the floor is sloped aft, whatever water is on the standing room will run aft and be out of the way, a measure of comfort that those who sail in rough water can appreciate. It is not generally known but a boat going at speed of four knots and over will, if equipped with proper scuppers, siphon, i. e., suck the water out.
