Some are still used as headfoils for doing peel changes for racing
. The instructions for my Harken
describe how to take off the drum to be able to use the full hoist racing sails. Mine is a real pain as the headstay has to be removed at the lower end. The newer Harkens come with a split drum so you don't have to release the headstay. Since I essentially don't race
, other than a couple of Friday night beercans, I do what the previous owner did, and don't bother taking off the drum. You take the feeder off of the foil, slide the top swivel down to rest on the drum, and put the feeder back on. The luff of the sail chafes on the drum this way. The only time I bothered to do this was to put up the lightweight full hoist genoa
in drifter conditions. If there was any wind
at all I just used the roller sail.
I suppose you could also use the other slot to rig a twin headsail for running.
