Any other lesser-known hulls in T-boat size?And how do they compare?
What else was used for racing besides the Allison, Delta, Voodoo, Critch?
Matt, you have listed the current boats.....In VP75 you do see other makes and models because of their 900 lb. minimum weight.
In 2019 VP75 did make a spec rule change......they are now allowed to modify the powerhead.
VP 75 TECHNICAL STANDARDSTotal Cu. In. Displacement Min. Boat Length Min. Wt.-Boat, Engine, Driver
45 to 49.9 cu. in.
13’ 900 lbs.1) Boats must be molded V-bottoms.
2) Capsule and roll cages are allowed.
a) Boats with less than 20” of molded depth at the driver’s seat (external keel to top of gunnel) must have a roll
cage per APBA Super Sport class specs.
3) Driver’s seat must not be more than 36” aft of midships.
4) Steering: Mechanical push/pull (Ride Guide style) or Cable and Pulley Steering is allowed per APBA OPC standards.
5) Engines must be visually stock production and mass marketed class E (49.99 cu.in. max. total piston
displacement).
An overbore of up to .040 is allowed. Internal modifications are allowed, so long as externally
the powerhead appears stock.6) Power trim is not allowed. Engines with factory power trim must be operable at the transom only, or disconnected. In
addition, all engines must be tied down to prevent kick-up.
7) Thrust jacks and upper mount snubbers are allowed. (No solid mounts allowed.)
8) Engine Modifications:
a) Tilt switches, oil injection and rev limiters may be rendered inoperative.
b) Two 1 inch diameter holes can be drilled in the lower unit above the cavitation plates (readily plugged for testing
and water skiing).
c) Cosmetic appearance may be changed.
9) Propellers - any through hub allowed.
10) Engines must be mounted such that when trim parallel to running surface, the center line of the propeller shaft is
located 5 inches below the running surface.
11) 20-inch midsection only is allowed.
