    Almost a fully equipped galley. I generally pack about 300 pounds of non essential gear.

    Two fishing poles out the back, and two set on the amas.

    My camera lost power on the full sailing video clip.

    Had a blow out on the dagger board cassette. 20170903_165133.jpg Nice to know, that it will still sail with one ama, full of water.

    Season is about over, probably one more sail.
    I patched the dagger board cassette using the easiest method possible, the band aid patch.
    I will probably store it up side down this winter, as to repaint the bottom.
    The trailer was built around a 1200 pound idea, the fully loaded reality is pushing 1600 pounds. 1.5" x 3" 11 gauge trailer stringers are going to stress crack, some time. Faster if I go on any long trips. It is also a built under the boat, prototype, crude but functional.
    I have some 1/4" 7" × 2" U beams to build a better trailer with. So it will keep me busy this winter, without any dagger boards to frett with.

    The 2"x4" beams on the trailer, are welded closed, it is built with gauge steel, so it is a mattr of how much rust has thinned the rails.

    Using the axles as saw horses, It is pretty light, 14 gauge steel.
    I used backing plates, were I welded the tubes that will support the ama crossmembers.

    Cut off the back 36" still need some 2" flat bar to reinforce the cross beams, that are rusted through, along the center bend.

    Need to add a toung extension, so I can launch with out getting my feet wet.

    Jacking up to remove old trailer, and putting a better one under it. Maybe some bottom paint.

    Trailer painted, and slide under to fabricate standoffs, and set bunk boards.

    Not sure what to call this apparatus. Standoff tube, maybe "cow catcher".

    If left about 6" above water when loading I can motor the trimaran and run it up on them.
    The tube will hold it in place, then a u bolt, locking pin will hopefully keep the boat from sliding back as I go up a steep boat ramp.

    The trailer has 4 standoffs, a 2x4 bolts in between them. It acts as a guide to line up on the trailer. I usually have to load up on the rough side of the lake. In a cross wind, it makes it a simple task.

    A trail blazing conglomeration that is quite pretty when it is packed up and on the highway.
    It looks really compact and ingenious on the trailer, a reverse origami ugly duckling/swan. I like the audacity in your spruiking something that is clearly not aimed at retail marketing[?] but utilizes the formula, wonderful irony, simply unbolt the eccentricities and lo and behold it becomes a runabout with an outboard, a fast river boat. It is necessarily unique and a stable platform for fishing, I tips my hat to the problem solving of your own making, I do a similar number myself , well done . A spinnaker might be fun on your craft, on its own. Another possibility is putting a large tent on the platform and run the tinny in and out and the solcat becomes an anchored go anywhere on water station. ,but you lose the sailing problem solving intrigue then. James Bond and Hobie eat your heart out, ha ,.. cheers. I wonder how this would perform if the donor centre hull was aluminium?

    It would have to be a very custom built aluminum boat, as the torque applied from the amas, lever effect, and the mast tension is going to destroy a factory hull. The hull twist before I foam cored and added glass bulkheads was scary in 3 foot rough chop.
