I lined the inside of my front and rear hatch areas with a thin closed cell foam pad (aka yoga mat) and it is sticky enough to keep the stuff I've stowed in place.
Didn't need to glue it in so, I just pull it out when it needs drying out in the hull.
Here's the stuff I used - http://www.amazon.com/gp/product/B002BRHPU8
Nice and thick and comes in colors to suit your preferences. The light blue one matches up well with the Dune sail and trim.
One roll (mat) is 72" long and gave me enough to do the front hatch area, rear hatch area and enough left over for some 8" wide strips to put between the amas and the hull when trailering to prevent scratching.
