New to an Asymmetric Spinnaker

[Bob F]

I'm just learning to use the asymmetric spin I got with the Hunter 376 I recently bought. It's a 1.5oz by North Sail (so sorry Doyle). I attach the tack to the spare anchor rolloer via a line & block that's lead back to the cockpit. Clew sheets lead aft (outside) to block to aft end then back up to winches. Two questions:1. Where can I read to learn about proper sail trim? Like when to let out or bring in the tack lead to raise or lower tack? When to bring clew sheets in or out? It seems if I let the wind (true) get too far behind me the luff edge collapses. Can you reccommend a decnet publication so I can read about how to trim this sail?2. At what point reagrding wind speed should I not use this sail. I would hate to get overpowered with this sail. I had it up in 15 kts (true) running a broad reach (abt 8 kts apparent) and it seemed ok, but close to my comfort level.Thanks, Bobs/v Andiamo

Flying the kite

Hi Bob, welcome to the Doyle Sails forum.Let me just give you some basics, as I'm sure there are some good articles written, actual sailing is the best teaching tool. Eventually, you get a feel for how to best trim your spinnaker.The sheet is your main control. As the luff of the sail fold in, trim the sheet. if the luff never folds, you probably need to ease the sheet. The exception is when you are too far down wind, the sail may collapse because it is blanketed by your mainsail.As you sail with your asymmetrical you will find how much trimming is necessary.Besides the sheet, you want to adjust you tack line to optimize sail shape. When tight reaching, the sail will be more efficient with the tack line tighter. When broad reaching, the tackline should be eased to allow the sail to project out in front of the boat and a bit to windward.As far as wind speeds are concerned, you are on the right track, "prudence is a virtue" Your sail will hold up to some relatively heavy breeze, but your comfort level is your best guide.

right here on this website. Type in "assymetrical spinnaker" in the Archives section for lots to read. Best angle seems to be with the wind on a broad reach, halfway between dead run and a beam. It will convert to a beam-reach apparent wind and push you just fine.Any angle lower that that risks an uncontrolled gybe that can knock your head off or worse (ie. dismasting). Higher angles will have the main blanketing the spin or turn it into a reach and collapse the spin.To mitigate blanketing, I've perfected an 8-foot steel bowsprit that locks into the anchor and propels the spin out 4 feet from the bow. It's inexpensive and proven. I can send you pix and directions if you email me your snail mail address at bodonovan@vagazette.com
