x82 Boy Scouts Every row-boat should be provided with a rough. sponge and a tin dipper to be used in bailing out the water. Always bail out the water after a rain and keep your boat dean and tidy. Sailing in Small Boats The most convenient kind of a boat to learn to sail in is a cat-boat, which is a boat with a single fore and aft sail held in place by a boom at the bottom and a gaff at the top. To understand the principle of sa?ng we must reali7e that a sail-boat, without the use of a rudder, acts in the water and wind very much the way a weather vane acts in the air. The bow of the boat naturally turns toward the wind, thus relieving the sail of all pressure and keeping it sha.king. But if by keeping the main sheet in your hand you hold the sail in a fixed position, and, at the same time, draw the tiller away from the sail, it will gradually fill with air beginning at the hoist or mast end of the sail and impel the boat in the direction in which you are steer- hag. Given a certain direction in wMch.you want to travel, the problem is, by letting out or hauling m your main-sheet, to keep the sail as nearly as possible at right angles with the direction of the wind. We must remember, also, that, while the sail. must be kept full, it should not be kept more than full; that is, its position must be such that, by the least push of the tiller toward the sail, the sail will begin to shake at the hoist. It is even desirable in a strong wind, and especially for be- ginners, to always let the sail, close to the nmat, shake a little without losing too much pressure. When you are sailing with .the wind coming over the boat from its port side you are sail- ing on the port tack, and when you are sailing with the wind coming across the boat on its starboard side you are sailing on the starboard tack. The port side of the boat is the left hand side as you face the bow while standing on board, and the star- board side is the right hand side. An easy way of remembering tMs is by recalling the sentence, "Jack left port." Direction of Wind Of course, you will see that, if you should forget which way the wind is blowing, you could not possibly know the right posi- tion for your sail; and t. hi? is one of the first requirements for a beginner. It is quite easy to become confused with regard to the direction of the wind, and therefore every boat should be provided with a small flag or fly at its m?ast-hea.d and you should keep watching it at every turn ofs?hebDoaOo?tolttthe habit
