How important is precise tuning of my split backstay on my '01 250? It seems a bit slack compared to the '01 of my sailing partner.

Frank... all that is required on the backstay is that it be tight enough to stay clear of the roach of the main.

It does have an adjuster to tighten or loosen. Forgot: should the backstay be loose in light air, tight in brisk air...or vice versa? Or just forgetaboutit

Backstay should be looser for light air...tightened for heavier air. By tightening the backstay it applys some mast bend pulling the masthead to aft pulling the luff thigher, flattening and therefore depowers the main. It also flattens and depowers the headsail by allowing less sag in the forestay.

Frank, Tony's comments about hardening of the backstay tightening the main are applicable to his C25 but not the 250. If your running full headsail and main, then hardening the backstay on the 250 will firm up the headsail but increase the draft of the main. There will be some net effect in reduced heeling, about 5 degrees in 15 knots.

However, if your running the main only... do not use the backstay tensioner to reduce power... as the opposite effect will result.

You are right Arlyn, I forgot that 250 have a single set of lower stays. Without fore and aft lowers or a baby stay, tensioning the backstay wouldn't be appropriate.
