The new 2023 Sunfish hiking strap. 73cm in length, just like the original Vanguard one. The forward end can be attached lower in the cockpit to give the sailor a more comfortable hiking position. If you have a boat with a HIN that starts with GB or PT (2018 or earlier) you just need 2 screws and a plastic plate (both provided in this kit),a drill and a screwdriver.
