Use the Sleeve
I own a 1979 H25. While not as big as your 260, the problems of using a Asymetrical Spinnaker (Gennaker, Flasher, Cruising Spinnaker, or whatever you want to call it) are the same. First, I assume that you want to use the gennaker in conjunction with the furled genoa (I do). There are, then, several requirements: a. a spinnaker halyard or a second genoa halyard; b. a sleeve attached to the tack of the gennaker which wraps around the furled genoa (because the tack stays attached to the fore stay, a spinnaker pole is not needed and gybing / tacking is similar to the genoa); c. a downhaul attached to the tack of the gennaker and running through a turning block (located on the deck as close to the bow as possible) back to the cockpit; d. and, of course the two sheets. Dousing socks are a definite plus as your gennaker will not inflate until you want it to (which may not be, and often is not, when you raise the sail). When its time to drop the gennaker, collapse the sail and lower the sock over it. Once, in the sock, the sail may then be lowered to the deck. I have handled my asymetrical single handed. It is not easy, but it can be done. Two people make it nice and three make it a breeze (no pun intended). You will find this sail is a lot of fun once you get used to it. Enjoy!
