when i'm on a port tack(i.e. the sails are on the port side of the boat if thats the correct terminology...or is it the side the wind hits first), anyhoo, i use the port side jib sheet to control the jib and let the starboard sheet hang loose (sails are on the port side just to clear that up). however, i saw a pic recently that suggests the crew was using either the starboard sheet or both to control the jib. is there something i'm missing about sail shape here. it always seems to me that using the starboard sheet put too much curve in the foot. any help?
