At one point she had four masts. Foremast with square sails. Main with a lateen, mizzen with a lateen and a sub mizzen with a triangular little boom and mast sail for going into harbor.
So I had to ask. I found a sailor and asked, how do they handle the lateen on a down wind tack?
The one lateen has about four feet of chafing wrap on it. But nothing like a parrel.
She said that on a true downwind tack, the spar is laid against the mast, rather than swinging it around. The way we catboat sailors do it.
