Out of production now, in fact I don't think they ever made it to true 'production'.

Oh no. I probably some pics somewhere. Will post them when I find them. Into the depths of the magazines once again.

According to 'Powerboat' or 'Hot Boat' someone else is supposedly putting them into production.

Hang on, I think that's been done too.
Sorry, I'll try and be a bit more serious.
One day.

Not a cat, but an awesome machine nonetheless.

Torque Marine has gone out of business. Dave Callan of Callan Marine and Mike D'Annibale of Sterling bought it out and are building those 860ci aluminium V12s now. Callan Marine has removed the 2500hp turbines on its Tencara raceboat and installed the Torques for a test platform.

Power is up from 1200 to 1350hp NA, with more hp to come. Torque had installed twin Vortech blowers making 1500hp, and Sterling may continue that motor.

Torque Marine built the motor with internal accessories that unbalanced it harmonically. Sterling will mount them outside with belts.

I don't know about price, but Torque was asking US$110,000 or so.

OK,

If you have a surface such as the hull planing over the surface of water, friction will increase along with speed.

So what designers have been trying to do for years is to unstick the hull and thus reduce friction, hence the stepped hull. However this caused a lot of headaches as the moulding process becomes more difficult with stepped hulls.

So if you take a conventional Deep V hull and pump air out through the hull and onto the waters surface you will disturb the water stiction and release the grip the water has on the hull by a significant amount and thus unsticking the hull from the friction and enabling higher cruise and top speeds for a lesser amount of fuel.

Comprende?
Several Vhull builders here are ventilating their stepped hulls with NACA ducts connected to vents in the front of the steps. It works.

I vaguely recall reading somewhere about someone experimenting with a dimpled hull (sort of like the surface of a golf ball) for the very same reason.

Actually, this may have been on a kneeboard, but perhaps the same principle would apply to a boat hull?
