Leg-of-mutton sail

1922 canoe with a leg-o-mutton sail (often confused with a lateen rig)

A leg-of-mutton sail (LOM) is a simple triangular sail set on a long spar mounted horizontally on the mast.[1] It runs in a fore-and-aft direction.[1] The leg-of-mutton uses a spar mounted high instead of a boom.[2] This gives the helmsman more visibility and there is no boom hit his or her head on.[2] It is a favorite type of sail for small boats. These include puddle ducks[3] and canoes.[4] A LOM is very similar to a spritsail. But instead of being square or having four corners, the LOM has three.[1] Instead of the spar being mounted diagonally, as with the spritsail, it is mounted horizontally.[1]
