    I'd try towing the 420. We actually get less drag from a planing dink than a cat dingy like the Livingston. Have you considered a demountable set up to allow you to use the amas as a cat again? That might be the best of both worlds, though on a cruise a rerig would be too much effort with the other things to do.

    Will be demountable...and folding....

    Planning on 11' beam - bit less than 80%. 420 hull alone is 5' wide at the gunnels, so akas won't be too long, about 2' 6" each side.

    PT hulls are 14" wide. Total beam (folded) can't be more than 8' 4" for towing. So I figure if I make the beam stubs about 8" out from the hull, and ensure the amas fold back against the 420 hull sheer, it should be just inside the towing limit.

    It won't be pretty, it won't be fast, but it will be cheap.... :)

    Why don't you just cut and hinge the akas at 3' 8" out from the centreline and fold back the amas over the cabin top, (or deck if you have no cabin).
    Worked well for me on my Piver "Nugget" 24'.
    Towed it on a standard rented trailer over a four year period with no problems.
    Just lashed the amas together with line over the top of the cabin. Simple. :D

    Pat
    I hear you - would be 'simpler' to do a Nugget-style folder, or even the Woods Strike type, but I has me reasons, and few of them are rational.... :)

    Basically, this boat is the first of three I intend to build/have built.....the next will be a Scarab-ish 20'er....like a modernised Bucc24...and the final 'retirement' boat will be the Farrier 10m for which I have plans, but with subtle updates and mods....like horizontal folding akas....

    See where I'm comin from / going to....?

    Gotta suck it and see *inexpensively* first..... :)

    Also, local river moorings are dangerous due to floods, but there is a narrow creek off a nearby river that I could use as a hurricane / flood 'hole' that requires a folder, and one that can motor folded, which Farrier-style boats *can* do, but not well according to what I've been told by owners.....

    Hence, forward folding. Experiment. If it works, good, if not, I'll wear the egg.

    I agree Buzz, it would not be a good idea to try and motor with the amas folded over the cabin.
    I had an International 23 catamaran where the akas slid into F/Glass mouldings. I would not have liked to try and motor that with the mast up.
    With the mast down it easily hauled out on to the trailer.

    Folding back horizontally is a whole new ball game. Tricky on a Cat but easier on a Tri. My son had a sweet little Dutch Tri which did that. Can't remember what make it was. :rolleyes:

    This *is* irony, yeah...??? :rolleyes:

    The Bucc-Meister refusing to acknowledge the existence of a competitor..???

    Or is there another Dutch horizontal folding tri besides Quornings...??? ;)

    And FTR, their's folds forwards to deploy, mine will fold backwards to deploy. Reverse process to fold in. [Whats the antonym of 'deploy'??]

    So which "folding back" were you talking about...??? LOL :D

    Sorry Buzz. You lost me there.
    Back/Forward, I'm not sure.
    But I am sure it was horizontally.

    For interest - collected these when doing the research. The last picture is theScarab 22 - used as the general concept for mine

    Sorry, OS7, was being facetious.....whatever horizontal folder system, it folds both forwards AND backwards, depending only on whether or not it is deploying or retracting.

    So the Quorning system deploys forwards and retracts backwards.

    Mine will deploy backwards and retract forwards.

    Obviously, both assume you stand at the stern looking 'forwards'.

    So the difference is in the deployment (or retraction) of one relative to the other.

    You wouldn't know I was a writer by trade...... ;)

    Hi Buzzman,
    I would like to buy a set of your Command 10 plans. I would really love to study these plans as I have been a fan of this boat for some time now. I'll likely never build the boat but would love to be able to learn from it. Thanks -Jerry

    If you'd read the Command 10 thread you would know that I gave Ian Farrier a commitment NOT to sell copies of his Command 10 plans, and posted on that thread the drawings he was happy for us to all see.

    As your two posts on this forum relate to attempts to purchase Farrier plans, I'm not sure I entirely believe your claim you may "never build the boat", but I'm sure Ian would not want someone - perhaps a potential competitor - "learning" from them.

    Forgive my cynicism if I am judging too harshly......but a poster with only two posts.....???

    Sorry for your distrust and cynicism. I have purchased farrier plans over a year ago but probably will never build it. The materials are expensive but the learning aspect of studying plans are fun. If you don't wish to sell, thats cool. I don't want anything to do with any kind of accusations involving you. The fact that you think something is wrong with two posts trying to buy plans is strange. Have a great day.

    Not really. Most people who are interested in tris and multihulls in general have posted more than twice, and their "interest for interest's sake" is well known to the online community as a result of those posts.

    It is certainly not inconceivable that a "potential competitor" seeking to build or market folding trimarans might attempt through subterfuge - posing as a scholar for example - to gain access to a competitor's existing copyrighted work.

    The internet is full of shysters, rogues and mountebanks. I am more than happy to accept that you may not be one such, but I hope you can understand the source of my - I would argue, necessary - cynicism.

    Your tally of two posts does not allow for Personal Messages, but when you have achieved the heady total of five posts, feel free to PM me. You may learn something of interest.
    :) :)
