Will do here in a few minutes Mark- I went ahead and copied the stuff from the WTC thread to keep everything here. Hope you dont mind.
Marks quote from the WTC thread-
What you can expect is a lot of fun. It is a drivers class!
The rules that went out several years ago are rather technical, Here is a simplified version.....
In a nutshell a Mod-VP must be a "keel rider". The keel can be of any design, flat pad, Vee, round etc. The keel must be a minimum of 1 inch wide at the point where it crosses the depth of any other ride surfaces. It must remain that way at least 40% the length of the boat measured from the rear. This keel aka center ride surface can be notched forward up to a maximum of 1 inch ahead of the rear of the hull. No part of the hull can be outrigged. Boat must steer with engine. Wings, spoilers, fins and tabs are allowed.
In the Storm series we encouraged outboard monos but no one showed up with any. Basically the rules are the same as the lifesize class was. Vee's and Tunnel Vees were allowed. If you look at my boat it looks like a mono on top but is a tunnel V. If you look at a Vision it is a pickle fork tunnel with a center ride pad. Mic's HTV is a mono with sponsons. The only thing we really don't want to see is a 3 or 4 point hydro with a keel added because it would still suspend the tail and ride on the forward sponsons. It makes for a fun class and there are many designs that can be explored and still stay within the rules.
Between my boat, HTV, Vision and Longboard there are quite a number of them out there. Be nice if it were in the rule book so everone could be on the same page. If you think about it NAMBA has an outboard mono class where IMPBA just has inboard. Mod-VP actually makes a very competitive class.
