Replacement foam,cut for the hull.

Field notes

Foam blocks compress after a few seasons and stop gripping the hull. Riverside® replacement pairs match the Deluxe and Standard kits for canoes and kayaks. Extra-tall canoe blocks clear a raised roofline. Foam-That-Fits is the adhesive-backed sheet for padding a rack or a cradle.

If the block leaves a dent in the hull after a drive, it is time to replace it.
