We are bringing a two person sit on top kayak on our trip. We elected to bring this type of kayak because they are virtually indestructible, easy to paddle and a great form of exercise. Given that deck space is always at a premium on a cruising boat, we were delighted to find a set of folding, stainless steel kayak racks that bolted onto our railing in a matter of minutes. The folks at Ecomarine ( http://www.sportsracker.com) have come up with a system that is ideal both because it is simple, rugged and keeps our decks clear while providing a secure cradle to hold our kayak.
October 15, 2014, crossing the Gulf Stream from FL to West End Bahamas, we were very pleased that our kayak stayed secure in the Ecomarine sportsracker cradle!
