Boats with One Mast:
Sloops: The most common type of single-masted monohull. Sloops have either a masthead rig or a fractional rig. If a forestay attaches at the top of the mast, the rig is a masthead rig,
and the mainsail and job are hoisted equally high. On a fractional rig sloop, the forestay stops about three-quarters of the way up the mast, and the mainsail is taller than the jib.
