    Lot of ama immersion on the Draganfly but its a nice looking boat. Don't know the specs so can't really compare it. Sea Cart 26 has foils in the ama that keep it pretty high. The specs on both would probably tell the story..

    The seacart 26 would be faster the dragonfly 28 is more of a cruiser/racer with quite a useable interior. Both good boats but different focus.

    The one falling from the sky is faster!

    I think conditions will make the difference. If it is flat and blowing less than 15K, Seacart will be minutes ahead (like in its video), but in open water with 1-2m waves and blowing over 20K, one could drive the Dragaonfly harder, so could be faster? Think of stuffing the leeward ama in a wave at 20knots... You might not spill but it will be on your mind...

    Some open-water footage of either tri would be nice, instead of the ideal PR stuff.

    Indeed, open water video with a bit of waves would be of interest. I have a hard time thinking these long, flat and steep hulls are meant to be used when lot's of waves, but I don't know. Possibly, the shapes stem from similar ones found on racing kayaks?

    each designer borrows from the last one so the newer design is almost always faster in multihull classes
    saying that these 2 boats are designed to do a different job

    If they borrow designs. Do they borrow imprinted patterns for the paint on the hull as well, like the patterns imprinted on the swim suits that were banned in the olympic games ??? ..i guess its the drag forces that create friction in the water?

    Powerabout is talking more about design features than taking hull imprints. Every boat is expensive to build and is a test bed of ideas for the design of future multihulls.

    Sharkskin style patterned panels have been tried on boats and seem to give marginal reductions in skin friction. I guess once every other way of making a boat faster has been investigated changes that give extremely marginal improvements like the one described will be revisited.

    Why not to count a racing point (TCF) each boat?

    I ask to forgive my bad English.
