Never got to building the upper shelf (was going to, with posts between hull and amas), but here it is for whatever is worth:
Details:
- Cradles made with 2 2x6 each, cut to shape, insulation rubber on top and all held together with outdoors carpet
- Lots of extra D-rings to hang loose stuff, and also to route the straps holding the boat so that they hold amas and hull separate
- Piece of extra carpet to soften the approach with the boat, overhanging the back edge.
- Hitch extension 4 ft (not 3), so that I can leave space between the boat and the vehicle towing it (for sharp angle maneuvers)
- Very low cost (had the 4 2x6 already in my garage). It's very nice in that the boat sits very low, which is convenient for beaching
- Built on a single day (another few extra hours before to create the cross-section templates - boat upside down assembled, tracing with a stick and pencil on cardboard)
- I used to carry the boat assembled, amas folded. Then walk to water in three pieces
Version 2 was going to make the cradles higher by 3 inches, so that accessories would travel below boat, and add the upper shelf. Ended up selling with Island before V2 came. Many more pictures of it at
