Kayak Katamaran Kabana
10/25/2012


I am ever in search of the perfect camping solution for different situations, and a recent post by FastYak on the CKC forum shook loose some ideas I had about a floating camping set up. I'm not thinking of a pontoon boat or a platform with flotation that could be towed by kayak to the location of one's choice. My idea is similar but more compact, which is appropriate for a small boat. 

Mountaineering and the relatively new sport of tree climbing/camping make use of suspended sleeping platforms or portaledges like this.  I have no idea how they transport the things but am assuming they don't climb up the wall or tree with the fully assembled platform hanging off their backs. Presumably it comes apart like a tent and can be stored more compactly. 

The thought of sleeping suspended that high is absolutely terrifying to me.  Being wide awake is no more comforting. I can barely even stand to look at the photos. However, the platform, minus the suspension straps is an idea that could possibly be modified for paddling. 

Such a kayaking platform would consist of two side poles and a spreader bar on each end (or vice versa) between which some kind of taught strong fabric is strung. The whole thing would be securely supported across the back and front decks of two kayaks (the "pontoons"). To get an idea of how the crossbars might work have a look at this photo of two double kayaks attached together like a catamaran for use with a Balogh Sail. For the Kayak Katamaran Kabana there would only be 2 crossbars. There would be some permanent mounting base on the kayak to which the poles would be attached. Pole length would be determined by the desired size, structural requirements and engineering limitations of the materials. The longitudinal bars would of course have to be attached in some way to the crossbars.

It could be a camping platform, sun deck, swimming/diving/fishing platform, etc. A tent could be erected on top. To reduce weight and bulk it might even be possible to use strong specially constructed paddles for 2 of the poles with those also serving as the spare paddles. Other dual purpose features could possibly be incorporated as well. Perhaps a folded configuration of the fabric could double as a sail with poles or pole parts serving as mast, boom or spar. Also, in heavy wave conditions having the two kayaks securely attached to each other could provide additional stability, more like a catamaran. 

If designed right it could be taken down and the fabric stowed in a hatch with the poles stored on deck as are spare paddles. Since 2 kayaks are needed for support there will be 2 kayakers who need a place to lay their heads. So a double platform like this Black Diamond Cliff Cabana would be needed.  For mountaineering these platforms must be over-engineered for strength given the consequences of failure. That also makes them heavy, the Cliff Cabana weighing about 20 pounds. Seems to me a kayak supported platform would not have to be that heavy. 

Has my imagination run wild? Probably yes. But it would be so cool to have a Kayak Katamaran Kabana - paddle over to a unique corner of the marsh or swamp, drop anchor or tie off to a tree, set up the platform and spend the night gently rocked to sleep on the water.

Any mechanical, structural or materials engineers out there with any ideas about how to do this?

  1. I want to see pics if/when you ever get this designed and put together! I wonder what the weight would be and how much room it would take up in the boat? Of course, having two boats going does give room for combining some things to save room, anyway.

  2. "If" is most likely the operative word. I doubt I'll have time to do anything with this idea until after I retire. But at that point I expect all you will see of me is the back of my car or the back of my kayak heading off into the wild blue yonder. I may be too busy paddling to design/make anything.

  3. I like it when your imagination runs wild! This is a great idea! You might be able to use two take-apart spare paddles as the spreader bars...

  6. Here is something I found that demonstrates the idea.
