    Thank you very much for the replies.

    No it's definitely not a red baron. Same size but RB don't have the step in the hull sides, completely different cabin, 1 companionway not 2 etc etc.

    There have been a few mini bridgedecks over the years, the most famous being the RB, Jarcat and little barrier. I know of a couple of others that are uncommon, but I've never seen one like that. I'm still not sure if it was ever a sail boat or always a motor boat. It has some design features that would be found on a sail boat, but no evidence that I can see of there ever being a mast step or rudders.

    Bit of a mystery. So much multihull history is lost :(

    Neglected like the boat is it does not look like a bargain - more like a sad disappointment and abandoned since years, heavy, small with restricted accomodations and of course not a sailboat.

    I can understand that you will not risk the eleven hours (Google) driving your car to have a look at it.

    In the absence of a name for it, might I suggest "Scary Cat " ?

    It's mostly the history I am interested in. It would not take a huge rig to make it sail, you could sell the enormous outboard for something, but as you say it's a BIG project. I'm just a bit concerned that someday people will want to know about the evolution of multihulls and there will be no record of so much of it.

    Yes indeed parts of the evolution will be lost. Years ago before my retirement I was underway in Europe in my vacations with my wife and a dormobile and visited "multihull places" talked with designers and owners and took photos (diapositives) as much as I could. Very interesting were the "one off" multihulls which I presented on a few multihull meetings - sometimes earning a lot of laugther. But the ideas were interesting.
    Most of them will be lost when a history of the multihull movement will be written. When I tried to get pictures of MAUI from John S. Taylor in some different forums I did not succeed though John claimed in an article of MULTIHULL INTERNATIONAL to have built at least ten of them. At last I found one small photo in a book of Edward F. Cotter.

    When I look at the pictures of the 20ft catamaran one of the problems seem to be the shape of the hulls. I may be wrong but I think there is not enough displacement and distribution is not helpful for a big motor at the stern. It may be corrected by extending the hulls and adding beam - but it will be a lot of work -- as you wrote. Maybe you will find a better project.- Good luck for you! M.

    I'm not much help but I seem to recall seeing an ad for one of those in one of my 1970s magazines. I have a very vague recollection that the name started with a K - Kalinya or something like that? I'll keep an eye out for it when I go through my magazine collection for something else.

    It was a sailboat, by the way.

    I recently bought a reasonably cheap Shark Cat 560 off Gumtree. Twin 115 outboard and I just picked up another two identical engines for cheap, also on Gumtree. There are some reasonable deals to be had. Four engines should be enough ! Just jettison major components as they fail, no opening the gizzards of older outboards for me.

    They were made by a guy in port kembla and we're his attempt at a jarcat type design. A mate of mine has one in boonooroo it doesn't sail particularly well the hull shape leaves a lot to be desired. Too much rocker and not enough buoyancy, with two people in the cockpit it looks like it's about to launch into the air. Needs transoms extended and the run aft flattened out to make something decent out of it. I'll find out the name if I can and post it for you. I think it's called a Karinyah 20 built in port kembla by a company called seamarans which i think is long gone.

    A guy on the gold coast did a much better version in foam and glass but i can't remember the name of them.

    Just for interest - not an attempt to replicate a Jarcat but just a means of reusing the hulls and other components recovered from my 6 metre trimaran that was stripped and torched by Sh#theads while on a mooring. The hulls are epoxy/strip Paulownia and the rest is mainly aluminium or marine ply. In this pictures, the winches and mast have yet to be fitted.

    Many bits came cheap from Gumtree like a lovely Skiff mast, sails in excellent condition, sounder/satnav, radio. 5Hp Tohatsu outboard etc. It has a good full sized berth plus one for my dog, a small galley and porta-potti and is trailerable. It ain't pretty but it gets me back on the water
