for me! I will search the net for dealers here in Canada. Tks again


You can carry a kayak on a rooftop without going to great expense with some
simple foam blocks, a couple of cam straps through the cab of the vehicle
and bow/stern lines. I transported my fiberglass boat from upstate NY to
the outer banks in North Carolina that way. It'll hold the kayak securely
but is inconvenient if you're going to loading/unloading the boat
frequently.

A step above simple foam blocks are removable rack systems such as the
inflatable one previously described and there are also foam block/strap kits
or plastic block/strap kits that you can get (I've got a set of the latter
variety in my basement). Again, they're less convenient than a permenant
rack system but they're easier to set up than separate foam blocks. The
following doesn't look too bad:

The ones that I have consist of for plastic pods with straps running through
them. The're padded with foam rubber to keep from scratching the boat or
vehicle.
