One Piece for Aft End

Whether you're hauling out for the day or trailering to the next big event, you need to provide support and protection for your keel to prevent it from rocking back and forth and causing damage.

The ultimate solution to this problem, they are made with a durable fiberglass exterior and a soft closed cell foam interior for contact with the keel, this product fits snuggly into the keel well to prevent any rocking back and forth. A molded "lip" on the exterior of the product fits up against the walls of the well, further supporting the keel and preventing the Keel Saver from sliding down.

We recommend using a carpet or felt piece for the front of the keel.

Halyard Clip by SOAK

Halyard Clip by SOAK SOAK Halyard Clip
Designed for Boats up to 40'

Designed to prevent accidental spinnaker launches when sailing upwind and to keep the halyard from fouling during tacks. Plus, it automatically release when you're hoisting, so it's one less than to worry about going around the top mark. Made of high quality Nylon with UV inhibitor for durability. Nylon attachment line included.

Works best with lines from 5/32 (4mm) to 3/8 (9mm). We have found that it works best with stripped line because covered line is too rigid. For covered line we only recommend it up to 5/16".
