    What should I look for in a boat design that will limit swash?

    Cyclops, it is something that pirates used to buckle. With the recent upsurge in piracy, folks want to minimise it as much as possible. :)
    Actually - it is a British freshwater-ism for "wake" (I kid you not...)

    High length to beam ratio and shallow draft.

    A flat bottom 26'6" x 4'3" describes a Bolger "Sneakeasy" very small wake at displacement speed.

    I love swash boats of 5 to 1 or greater.

    Fine entry and minimal transom area can also help, in addition to the factors mentioned already. A canoe, even when pushed slightly beyond hull speed, still makes almost no wake- thanks to 5:1 to 8:1 length:beam ratios, and very fine bow and stern that cut the water smoothly and allow it to come back together smoothly behind the boat.
