Re: main sail blown?

I would define a "blown" main sail as one who's belly is deeper than 15% of the measured foot of the sail. A 15 ft boom length should only result in a belly 2 ft deep. If the belly is deeper, you would benefit by a newer main sail. However, I believe if you have lee stays drooping, you need to tune your rig. The weather helm is because of poor rig tuning and not because of your main sail.

Rule of thumb is extreme weather helm =your forestay is way too loose. You could tighten it and see if that fixes it....Although in tuning a rig this is not the first control you start with. Have a look at the Selden tuning guide and do it right.
