The Hobie Tandem Island Cradle Set keeps your Tandem Island from getting dented while its being transported on a trailer or a set of car racks. The cradle attaches to your trailer or the cross bars of your car. The cradles do not come with installation hardware but feature holes where bolts/washers can be attached to mount the cradles. The cradles come with foam adhesive pads that protect your boat while in transit.

Works much better than other saddles for Hobie kayaks. Before I purchased this, I had the Yakima landsharks. These are about 20x better than those if you are car topping your TI. The grooves are meant to fit the Amas as well, but you're definitely not going to car top the kayak with the amas on. I'd imagine that these would be even better on a trailer.
My buddy in Phoenix got his Tandem Island pretty warped because he refused to get a cradle for the trailer. I got one because I like to protect my pruchases and my TIhasn't seen any damage since I bought it two years ago. A necessity if you are trailering your Tandem Island. The instructions suggest a 67 inch spacing between the cradles, bolt to bolt, so keep that in mind if you are building a custom trailer.
