Re: hull extension in progress with picks
Hay Bud looking good !!! UUUMMMM I dont know what they call it when they have a step in the hull like 3/4 of they way back , where it rides when its on plane !! do you know what i mean ?? and are you putting it on yours ?? John
yup john....its called a step.......it allows air under the hull at plane.
oke mannerfelt is credited with the first engineered production step...(the bat boat)...racing boat drivers have been doing it for years.
i really really really wanted one.
but mine wont have one.......
steps are funny things......to work correctly, the plaining surface of the boat must be 18 inches foward of the step. if not on plane, the steps will actually cause major drag (kinda like a huge hull hook !).
the problem is, in our pleasure craft, the plaining surface is not a constant. different speeds, passenger loads, fuel levels and personal gear loads, will play havoc with a plaining surface.
i could never be assured that it would not create drag instead of the lift, so the idea of the step was scrapped.
during major investigation of stepping the hull, i found that the racing crowd was the only one that really benefetted from the steps, as they know exactally where in any givin situation, the plaining surface will be...so they build the boats with this in mind.
i was told by a very reliable source, that in production boat building, they feel it is easyer to sell a boat with a step. so they just guess where they go put them in and say the boat has a stepped hull !......(but they dont work worth a darn cause they arent engineered for the boat/motor pkg)
i would just love to feel the difference of a true stepped hull.
the oke mannerfelt bat boat is being produced locally by the former owners of campion marine. (they are currently working on a 44 foot carbon fiber version for racing)........i wonder if i can beg a ride !
