It looks like this is a very necessary piece of equipment for us to have here in Cayman.

“With all that recent worry about taking windsurfing kit on board those nasty airlines, it’s about time someone came up with an alternative! Just head down to your local marina and load your kit into the custom built hold and off you go, cruising the west coast of France before heading to Portugal, Spain and across to the Canaries! Or why not have in permanently moored in some Caribbean Isle ready to do battle with the tradewinds every winter.” – http://worldwindtravel.blogspot.com
