    I will keep that in mind next time I design a trimaran. In fact, I though a small small bit on it... but then, what the hell :)
    Seen bigger trimarans with smarter set-up for main sheet and track

    That's not very helpful.
    You could extend your boom and use a straight track, or move the curved track back over the rear beam.

    I would have suggested moving the whole rig/ front beam back if you were just starting. I never could decide what the benefit was from having the rig forward.

    Just noticed how fine the front of the hull is. It wouldn't have been my initial assumption, based on having sailed an old style Tornado and being concerned about submarining the bow. Both main hull (downwind) and outrigger (beam reach).

    After beam is fine in its position, makes a less flexible platform - but the easiest and simplest solution to reduce leech fall off is to extend your boom - and spread the main sheeting tackle - otherwise you'll bend/break boom if using single point main sheet position which is too far aft.

    Corley epoxy coated

    You could use a barber hauler that attaches to the outside of the rear beam to help adjust sail shape. It is a bit unwieldy though.

    I have a Bethwaite HSP fun to sail packs up into small package can transport on roof racks fits in a single garage beside car.

    It's designed to sail on mainhull the floats are really training wheels you keep them out of the water to go fast.
