Found an old ocean kayak scrambler at a nautical flea market for $140. A little faded but no major scratches or cracks. Only factory rigging.
Removed the old straps and added eyelets and bungees to the stern and bow. Added round Gaspachi hatch, side handles, and side bungee paddle holders. Added 2 rear and 2 front flush mount scotty mounts.
Add the seat and a custom milk crate and we are ready to go.
Just got started on a similar Scrambler resurrection project (see web site). I'm still mulling my hatch options. Until reading this, I was going to restore the straps, but now you have me strongly considering bungees...
