hooters have to be really flat to furl

that means they are a reaching sail more than a downwind sail

in light winds, <5knots, you can often creep a few degrees up wind with them, angles about 85 - 120 degrees off the wind

in medium winds, 5-10knots, they run best about 100-120 degrees off the wind

in strong winds, 10?-15knots, about 120-160degrees off the wind

if soloing with 3 sails you generally cleat off the main and jib in pretty much their reaching positions and then play the hooter and steering with each hand

be ready to steer down hard and release the hooter sheet once the leeward bow looks to bury
