REVISION TO RULE 5.01 DECEMBER 20, 2009

A. Boat used for towing skiers must not exceed 6.5 meters in overall length. The overall length is measured between the two perpendiculars, one at the bow of the boat (A), the other at the point where the bottom intercepts the transom (B). (See diagram #1). Intersection of keel and transom is key to all other measurements.

B. An extension shall be for the purpose of mounting an outboard motor (s) or a drive leg(s) to the transom of the boat used for towing skiers. The extension can be attached as a fabricated bracket and bolted to the transom or it can be molded to the transom of the boat used for towing skiers. Maximum length of the extensions and power unit (s) combined shall be 1.4 meters. There is a minimum dimension of 150 mm (6") measured from the lowest part of the extension to the intersection of the bottom of the boat to the transom, or the projected line of the transom if it does not continue to the bottom of the hull. No part of the extension shall be in the water while the boat towing skiers is on plane.

C. No "COSMETIC" extensions or protrusions are allowed in the 150 mm (6") NO GO ZONE. (See drawing # 2--View to transom) Adjustable trim tabs ARE allowed in this 150 mm (6") NO GO ZONE.

D. The length of the outward chine shall be limited to 6.60 m in overall length (A to B-1 see Drawing # 1) This allows for some design in the outward angle of the transom, the additional .10 m is equal to 3.937 inches.

Drawing # 2 with top vies, side view and view to transom are part of this rule. B - C is defined as----Transom to propulsion point (e.g. end of propeller shaft, nozzle of jet unit, 1.4 m Penalty 12.03.
