I'd head to a place like Home Depot and choose some type of silicone sealer
that's designed for clinging to smooth surfaces like tile, tubs or glass.
Since you'll need a lot, focus on the tubes that fit into a caulking gun.
I'd use sandpaper to rough up all the plastic surfaces, and then wipe them
clean with rubbing alcohol. First, apply the sealer to the top edge of the
box where it touches the lid. Give it a day to dry (no matter WHAT the
instructions say about how it cures in 4 hours). Then, flip the box upside
down and load the sealer heavily into the seam under the lip of the lid.

Make sure that kayak's tied to something on land, just in case...... :-)


Yer talkin' to someone in the "Land of Four Hurricanes". Heck, yes, we tie
things down ) All except for the 15'x5' skylight that few over onto the
top of a palm tree )

Plan on keeping it at front end of boat slip, tied to dock
and seawall.Does your advice to use silicone sealer come with a guarantee?
Does anyone know how to compute how many 12x24" (bottom dimensions) I
will need to float a 50# kayak and a couple of 1x6 pressure treated
boards? Plan to build very simple framework that will just lay onto the
plastic containers, with longitudinal boards protruding above the
lateral members so's the kayak will slide up onto it; probably bevel
long. members on one end to help it along.
