The V 20 hits 50mph tops, but any faster ?

Fellas, Fellas, the fish don't swim that fast. I like to get there in good time too but it's a V20 not a bass boat. Once you reach 60 mph windage issues become a much larger part of the equation. The company I work for put Gas Turbine engines in go fast boats back in the years. One hull I can remember was a 43' Black Thunder. We put (2) 1400 hp turbines on surface drives, she ran 108 mph and would start trying to swap ends (turn around) after 95. The boat builder claimed the bottom was engineered for 75 mph. The person that pointed out, in the above post, that deep vee hulls will continue to climb out the water the faster you go is correct. Couple that with the windshield, height above the water, load and ever changing natural wind conditions could provide a recipe for a crash. The good thing is the stability issues will probably scare the crap out of the driver way before the hull loses its grip on the water. Remember fear and respect are still the best throttle. I have been 142mph in a Nortech 50' supercat with twin 1400 hp turbines, great ride, rock solid. But it demanded respect at that speed, I would be very careful and creep up on that 60 mph mark for a V20.
Calm winds, little other boat traffic and light on fuel is what I would look for. As a general rule for every 140 pounds of weight added to the boat you will lose 1 mph. That number is a little askew for a V20, it was part of a formula for much higher speed boats but brings attention to the weight vs. speed issue.

It's me again, my above reply may seem a bit out of place. I only read the first page of the thread then posted, not realizing there was ten pages more. (forum rookie mistake). I am glad to see the goals were achieved and no ill handling was had.

There is a gofast cat with turbines running around Barnegat Bay where I live. That thing is blazing fast. I got a few pics of it bafore it took off one day. I have been told it does 140+ mph

1. That guy is ready to roast some marshmellows.

2. I wonder what the insurance carrier would say to that one.

3. What does a gallon of Jet-A run these days.

That fuel must not cost too much for that guy. He runs around in that thing almost every weekend during the summer
