I installed the Doyle cruising pack and love it. No more having to go on the cabin top to drop and cover the main in rough seas when the wind picks up. Very nice system and makes going out for a sail less of a hassle. You can wait until back at the dock to zip it closed and I leave the halyard on to quickly raise and lower the sail. You can release the lazy jacks and roll the cover against the boom for a clean look and better aero while racing.
