These ropes in
nautical language are called "sheets." The boy at the rear was the pilot
and did the steering, because his position behind the sail gave him an
unobstructed view in all directions. When changing tack the sail was
lifted overhead to the other side of the crew.

The Single Swedish Sail.

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.
The Lanteen Sail.

The lanteen sail we found to be a very good rig.
