Re: Rigging up an A-sail
Rig it outside the forestay.
Post a picture of your masthead bits, or draw a sketch and post it.
You'll need a halyard, internal is better in most cases, but external works as well.
The tack line needs to be adjustable and preferably in front of the forestay, but attached somewhere on the stem works well. I would not tack it behind the forestay.
Do you have turning blocks at the aft corners?
How long is the luff on your chute compared to the forestay length?
Now for the news you don't want to hear:
If you're already getting a 12 sec. credit for not flying a chute, and there aren't many DDW legs, then you're not that disadvantaged and need to find improvements elsewhere.
