She does have a boom vang and the reason the sail is shaped so weird is cuz the mast got snapped in the building process and its now shorter and when I get a new mast ill slip it back in but the sail is crunched due to the shortened mast. And the sails are very strong, dont know the exact material but its almost like they took nylon string and criss crossed it and put it through a laminater. Just finishing the sheeting system now and will take for a test sail when the new mast comes in.
What's a signature?????
