The first prototype is hung from the rafters where I plan on it staying while I work upon the second in order to prove that it cuts the mustard as a vessel of any kind: a reason being that wiring four motors up for any sort of vertical lift is an expensive pain in the ass that leaves you reliant on experts who'd rather do something else.
You can see here how those uPVC extrusions are overly flexible, though it's not so much of a problem in the fulness of time as (a) it provides shock-absorption in an industry wholly lacking it and (b) skis of all types have evolved from planks of wood to composite engineering marvels and there's no reason why these shouldn't too.
Fortunately the second prototype ~ aimed at motion under displacement and on the plane ~ has wooden hydro-skis which as ever are provided by Cheshire Mouldings.
I told them that I'll rate them for maximum velocity on smooth water for a fee, and the best thing is they're from down the road here in St Helens.
Think global, buy local, eat pies.
