I see that John decided to not print any sport 20 hydro rule proposal for discussion in the IMPBA Roostertail.
So If you have a boat to be setup for the 2005 race the strut can be under the boat or on the transom. I know a couple that built boats this year with strut on the transom.
The Gas Sport rules allow this and i suspect the sport 20 hydro will go this way too, since they will allow this at the Internats race, so it follows that sport40 should be ok with that change too in the future.
Hope the IMPBA board will get all the sport classes setup with the same set of rules. Less confusion i think would be a good thing.

Bill Zuber posted this to be used for the 2005 IMPBA Internats race.
These are the RULES that will be used at the 2005 Internats !
Not the proposed rules that John Equi is posting in the December Roostertail.

• Boat must be inboard powered.
• Hull must be a three (3) point hydroplane configuration and resemble a limited or an Unlimited hydroplane design of past or present. Hulls NOT permitted: outrigger, modified outrigger, tunnels, or canard hulls.
• Boat must have a name, or sponsors name, or logo, or a racing number affixed to the hull. (A local or national or fictitious sponsor name is acceptable.)
• Hull shall have a minimum length of 27 inches, and a maximum length of 35 inches. If the bow is recessed behind the tips of the sponsons, that recess shall be no larger than 25% of the overall length of the boat. *
• Boat must have a driver in open cockpit or simulated enclosed cockpit.
• NO part of the strut shall have a width greater than ½ inch or a length longer than 2 ½ inches.
• See sport hydro hull pictorial for clarification of Sport Hull configurations.

What the IMPBA board finially decides to do will take some time im sure, but we will have some guidelines to go by till then.
