    Webster, Shark (and various clones), Noosa. I think it was a 9m or so Noosa that I went on last time. Not my boat. She went well and handled amazing. Example, whale breach directly ahead at WOT and massive swerve with no dramas. As a passenger. I did feel a bit disconnected from the boat but am sure as a driver, that feeling would not be there

    The boat bajansailor posted would be too small for your purposes, I'd think, and I am wondering how that boat could manage a couple of 50hp 4-strokes, a lot of weight aft. The power cats that I have seen that have the rounded hulls, all seem to porpoise more than is desirable, too.

    BTW, this is the first proper boat that I ever tried to make. There is a log somewhere on boatdesign. Built in a remote location so I had to fabricate things with basic tools as unable to buy

    Built with home made plans for hull and shape is from intuition. Two different aspects coincided to create an unintended passive sum that had the nose holding straight. Turning that active would in my imagination take care of the problem in most hulls.

    Can anyone guess from the pics what that might be? There is a vid in that lot that shows her arriving through the chop and getting off the plane without any nose bounce. It's taken at 60x optical zoom

    I have never cared about holding info back, knowledge and ideas bounced of others can send the results higher and if it profits anyone then all the power to them ;)

    The side skirts form spray and flow channels as well as fenders. Cockpit is liner is inflatable with protective cushions adding air bag effects. Things like steering wheel and controls recessed into depressions in the liner

    I have a really poor mouse. The good one got smashed up, falling to the floor. It is really hard to do things with it. Need to pick up another good one, then will smooth out the lines more. Now keep in mind this is drawn assuming ply in the program. Fabric can be developed tighter and will have convex surfaces on inflation

    Question; best hard points for mounting disruptors and beam weapons? :D

    Don't read too much into the look of the thing. Just an attempt at the wow part of the SOR

    Thats all the hull pics for now. Next some drawings of things like stringers and such and somehow present the anti nose bounce concept

    Imaginative, but perhaps not practical, just stick to three-view rather that 3-D so we can see what you envisage

    It packs to down to a tube just over 1m dia and just over 6m length once deflated, with a rigid tail wearing a prop. I have a trailer for the 20' cat. Once that boat is moored, then the trailer will sit idle. Can be docked with the cat on the mooring too. Will fit next to the car in the carport too sitting on the ground/dolly

    You are talking about an air prop ?

    Why do you think they are not seen on boats outside of swamps ?
