Whether in steel, wood or extruded aluminum – this boat trailer is a great way to transport two boats at the same time.

7 Responses So Far to “Boat Trailers – The Double Decker

    I added two sets of trailer guide posts to a jet ski trailer, and my trailer guy made two aluminum crossbeams. I have hauled a Sunfish on the bottom, Super Sailfish on top and Super Sailfish MKII suspended from the crossbeams. 400 pounds total. Also works great as a lumber or metal roof hauler, 16 footers, no problem. With some adjustment I think I can put my Penobscot 14 on the bottom and wooden Sunfish on the top…or canoe or kayak or a deck for bikes, coolers…

    I found a Jet ski trailer for 300 bucks. I modified it a bit with a rack and now it holds a Sunfish on the bottom, and my B & B Spindrift 11N on top, and sometimes two canoes and two kayaks. Jet ski /PWC trailers are a good cheap platform to start with.

      At OCH, we call that “boat on boat action”.

    I’ve been doing these for maybe 30 years, mine are wood. 4×4 cross members and posts. Framing hardware. Furring strip diagonals. A half lap cut into the 4×4 to take a 2×4 on edge which is removable ( bolts with aircraft nuts) I run mine out to five feet so I can get wider boats on. Aluminum bits weren’t around when I started. Advantage of wood is that you can notch it to hold stuff like a boat dolly that rides on the top with bunks for the ducker. You can also put on gutterless rack fittings from places like Yakima if you want to convert to a double decking kayak trailer using roofrack stuff.

      Hey, thanks Ben. Your trailer was the one that put this on my radar. When I get back from boat-festing on the west coast, I’ll pop up a couple photos of yours, and of my own that I loosely patterned after yours… my 12 year old son and I knocked it out one afternoon… great project for us both to do together, including the refit at the hardware store 20 miles down the road when we found it “slanted”.

    Neat! We don’t need a double decker for our 1927 Old Town Canoe, however, you shared some innovative ideas I’m going to shamelessly “steal”.
