The? loose footed full battened main sail I bought from Rolly Tasker (thesailwarehouse.com).? ?I seem to recall that it cost me about $1800 - that must be almost 10 years ago though.
The loose footed aspect of the sail really improved our ability to shape the sail since we really had to make our outhaul work to flatten the sail.? Loose footed = No bolt rope.
The new main allowed us to actually sometimes finish our races in 1st place when we were normally the back of the pack with the old blown out main.
