sheet (cloth) and sheet(rope attached to a sail) are first cousins.. they both trace there way back to germanic base *skuat, *skut "project" -- which also gives us scot-free!

*skut gave us two old english words, scete-- which became sheet of cloth.. and sceata which sail-rope

other words derived from the root include scuttle, shoot, shot, shout, shut, and skit! I wonder if a racing scull is related too? or a scupper?
