You do not You may think that sailing is a difficult sport, but it is really not hard to learn it. need to be strong. But need to be quick. And you need to understand a few basic rules about you 本本 the wind. First, you must ask yourself, “Where is the wind coming from?

When you are tacking, you must always keep the sail inside the boat. Tacking is the most difficult kind of sailing. It is also the most exciting. You have to watch the sail all the way. The wind may change suddenly. Then you must be ready to change the sail. These are the basic rules about the wind direction. It may be difficult to follow them at first. Sometimes it is difficult to know where the wind is coming from. But soon you will learn to feel it く on your face. Before long, you will easily be able to sail the boat. But remember - do not go out alone until you really know what to do on the boat. Sailing a boat is fun, but before you can enjoy it, there are many things to learn. 【note) from ahead or behind 「前方からか後方からか」 flap 「(旗などが)パタパタとはためく」 back and forth「前後に」 tack「ジグザグに進む」
