Most boats will stand rather more wind when it is on the beam than they will when they are close hauled. For while they do not feel it quite so hard, it is easier to keep good way on, and you can spill the sails by slacking the sheets as much as you like without fear of losing it. So that in smooth water you will be as safe in a blow with the wind abeam as you are when sailing close to it and luffing up into the puffs. But a beam sea is the most dangerous sea of all, and when it is heavy you must always be ready either to luff up towards it, or to keep right away before it, as may be best. But if you do the former be careful not to have too much way on, or you will run your boat's nose right into the sea. If your course gives you a dangerous beam sea the best plan is to keep your luff until your port is well to leeward, and then up helm and run for it.
In running before a strong wind and a dangerous sea do not attempt to carry much sail. It is a common belief among the inexperienced, founded upon nautical literature absorbed in youth, and even amongst some who ought to know better, that you must carry plenty of sail in order to run away from the sea and avoid being pooped. But, in the first place, you cannot run away from the sea, which travels more than twice as fast as any boat can sail, and a press of canvas which buries the boat's stern as it drags her through the water increases the danger of being pooped. Moreover, it makes her harder to steer, and increases the much greater risks of broaching to or running the boat under water in those desperate rushes on the steep front of the big seas, which are at once the danger and the delight of running before a wind. So far from its being desirable to emulate the pace of the sea, the sooner the wave passes the boat, and the shorter, therefore, these rushes are, the less is the danger.
I learned this once by experience. Many years ago, on the coast of New Zealand, I was caught out at sea by a gale of wind in a 13-ft. sailing dinghy, and had to run home before it in a short, dangerous, rapidly rising sea. The little boat tore before the wind under a reefed mainsail and jib, running her nose and stern alternately level with the water, until it became evident that we should be swamped in a few minutes. I ordered the man who was with me to haul down the sail. The moment he did so the little boat, which was sharp at both ends and was steered with an oar, began to ride the seas like a duck, and we ran home before the gale with ease and safety under a bare stick and a fragment of head-sail.
A boat with a sharp stern, steered with an oar, has a great advantage under such circumstances. For the rudder is sometimes right out of the water and useless; and though the water of a great wave does not really move forward with the wave as it appears to do, the breaking top of it does, and when the rudder is in this water, which is going faster than the boat, it is useless for the moment. It is well to have a place for a crutch in the gunwale far aft, so that an oar can be used to steer with if necessary.
There is generally less wind under the shelter or lee of the land. But this is not always the case, and the most experienced seaman cannot always foretell whether this will be so or not. Sometimes the wind seems to belong to the land, and there may be little or none of it out at sea. Under high land—cliffs or mountains—you may lose the wind altogether; you may find it blowing in occasional baffling puffs of great violence and uncertain direction, or you may find it blowing much harder, not in puffs merely but altogether. It is not an uncommon experience, especially in the Mediterranean, to run down a coast before a fresh breeze, and to find a perfect tornado blowing when you turn a corner and luff up under the land. This is one of nature's paradoxes—one of the undoubted facts that one occasionally meets which seem opposed to all reason and probability. I do not know how far it has ever been scientifically explained.
Some places where there is high land seem to brew their own wind. Loch Scavaig, in Skye, under the Coolin hills, is an instance of this. It may be fine and almost calm outside, but as you sail into its gloomy waters you may find a perfect tempest blowing in or out. It staggers one to think what it must be like in a real gale of wind.
In Carlingford Lough, Ireland, last autumn, when there was but a fine-weather breeze blowing outside, the puffs off the mountain on the south of the lough took the form of a succession of regular waterspouts, any one of which would have twisted the mast out of the boat or capsized her if it had struck her. We kept as far to leeward as we could, and most of them died away before they crossed our track, but they felt very uncanny.
Speaking generally, high land is always dangerous for boat-sailing, as well as trying to the temper. On a day when there is nothing but a fine-weather breeze elsewhere, under high land you are liable to get puffs as violent while they last as a gale of wind. It is as though the hills bottled up and concentrated the wind, so that when it is let loose it comes with double force; and these puffs are specially dangerous to a boat apart from their force: first, because the angle at which they will strike is so uncertain, and secondly, because, coming from above and striking downwards, a boat does not relieve the pressure on her sails by heeling over as she does when the wind blows horizontally along the water. This is the reason why you will probably find that the squalls that go nearest capsizing your boat are not those that you have seen tearing towards you turning the water into smoke as they come, violent as these may be, but those which you have hardly seen a sign of on the water at all, and which strike the sails with a downward blow straight from the mountain side. The Sound of Raasay, outside Portree Harbour, when a westerly wind is blowing over the tremendous cliffs of Skye, is a fine place for the study of these phenomena.
When the wind is blowing up or down a channel with high land on either hand, the fiercest puffs will be near the sides which seem to concentrate the wind, and the safest place will be the middle of the channel. One day, in Loch Scavaig, beating out of that inferno of furious winds against the usual succession of tearing puffs, with double-reefed sails and all passengers down in the bottom of the boat, I stood rather far over one tack under the high mountain on the west side. Just as I was preparing to go about a furious blast struck the boat like a cannon-shot. I thrust the helm down, letting fly the mainsheet. The foresheet fortunately carried away of itself, but for a few seconds a volume of water poured over the rail, and I thought we should go over or fill. A minute later, as we were standing off on the other tack, setting things to rights and pruning our ruffled plumes, my coxswain, a most excellent boat-sailer but a man of a somewhat sardonic humour, remarked grimly, 'I should think that would be a lesson to you in future not to stand over too far under high land.' It has been.
Here follow a few of the things which it is well to remember when boat-sailing, whether you are acting as captain or crew, or both in one.
