A large felt covered surface protects the hull of your kayak, and allows it to slide on when loading. Unlike two-part cradles, the one-piece design prevents the kayak from falling through. Additionally, there are no width adjustments that need to be made to fit the kayak. Just put them on, line them up front to back, and you’re ready to load your kayak.
The Marco Vee saddles fit a large variety of hull designs. Vee hulls or round hulls fit great, however if you have a very wide and flat bottomed boat, they do not fit as well.
