I was in this boat once, back in the mid to late 90s, for the "Radar Shootout". I remember the button marked "showtime" which dumped and ignited fuel causing the flames to shoot out. That day we saw 177mph. We went so far, so fast, I remember somene saying, "are we still in Barnegat Bay" and someone else said "I don't the we are in NJ anymore".

Great guy and a great boat.

Incredible. So what was top speed?

Her top speed was 69.6 knots or about 80mph. If I recall, a fuel tender met them at pre-determined coordinates out in the middle of the Atlantic a few times to issue fuel and supplies. The dam thing was like a speeding tanker!

She also had a bit more than the turbine

Quote:
Total, (2) MTU 16V396TB94 diesels each generating 3,480 H.P. are coupled to KaMeWa #63 waterjets. The gear boxes are AFBU7755's. In addition there is a diesel fuel burning Lycoming Marine Turbine #TF40 developing 4,500 H.P. coupled to an ARNESON surface drive turning a Rolla REXP 5 bladed cleaver. Fuel consumption is approximately 317gals per hour at 45 knots under the MTU's only, giving a range of approximately 1250 nautical miles.

Fuel
Consumption: 1,200 L (317 gal)/ Hr at 45 kts (Diesel engines only) / 2,300 L (608 gal)/Hr at 63 kts

Fuel Capacity : 37,000 L (9,774 gal)

Now we use a Brake and Crashboxes to shift.

Here is my setup

I have a question on your setup. I'm kind of lost here. When you apply the brake, and it stops the propshaft, is it also stopping the turbine from spinning?? Or is there a disconnect somehow?

Darrell.

The t53 is a free wheeling Turbine
The N1 (gas producer) is completly independent.
The N2 is the power turbine.

The t53,s ouput shaft (n2) can be stopped at ground idle
for up to a minute.
About 12 years ago Ted McIntyre from MTT developed
a braking system to bolt to the output of the t53 then attached
a scs crashbox. This is the same technology used by most today.

This will keep you busy

Thank you for the response. It makes a lot more sense now.

Ted was not the first to do this.

I do not know "who" was the first. All I can say is that in the mid 80's we had that on the PT6's we ran. Nothing new, nothing special, nothing hi tech. A brake caliper, a brake rotor, a hydraulic line and an apparatus that applies pressure to make the caliper apply force to the rotor to stop the N2.

Maybe it's my old eyes and the resolution. But right at around 3:05 into the vid, didn't he accelerate right in front of a dinghy? Looked like they were taking cover
