Best Foam Block Kayak Carriers
As an Amazon Associate I earn from qualifying purchases.
Foam blocks are the budget answer for a bare roof or an occasional trip. They spread hull load across the roof panel and cost a fraction of a rack. They also demand more care, because nothing is bolted to the car. The setup relies on straps through the door frames, plus bow and stern lines to stop the boat shifting fore and aft. Blocks differ in foam density, whether they sit on the roof or clamp to crossbars, and how the shape matches your hull. We weighed foam that holds shape under a heavy boat against blocks that compress flat, strap kits that come complete versus ones you must supplement, and how the grooves match round or square bars. Roof-only blocks suit short trips at moderate speed with a light boat. Bar-mounted blocks suit anyone who already has crossbars and wants cheap padding. Always add bow and stern lines with foam.
