Another sail of similar form, but for use of one boy only, is shown in Fig. 10. This had a height of six and one-half feet at the forward end and three feet at the rear; and its length was five feet. This sail was very satisfactory in light winds, owing to its great area. In use we found that it was very important to keep the lower edge against the leg, as indicated by the arrow. The rig was manipulated just like the double Swedish sail, lifting it over the head when it was desired to change tack.
