    All I can remember is that when the towline drops off the silence is mesmerizing......
    It's quiet with a sports canopy?

    I traded my trusty H-301 Libelle for the venerable 1-26.

    Looks “zippy”! Is the idea with that hull less drag? (Contact with water)

    That's the whole idea behind a 3-point hydro. The sponsons are just there to keep the hull level on the water. In a perfect world, only 1/2 of the prop would be in the water and the sponsons would "dance" on the surface just enough to keep things under control. The entire hull would ride on a cushion of air. It pretty much does that when running straight, but turning creates a lot of water drag. In the video, you can see it accelerate rapidly as it straightens out in the backstretch after turning.

    The other idea with that hull is to make a semi-scale model of a full-sized boat.
