Yeah, it was a different life, I had a problem having one motorcycle, so I had them all over the place. I worked on 3 or 4 in about 18 years, the one in the movie was the last one I worked on, it had 2 Paxman motors, very good power to weight ratio. 1350 HP each. I was on that one a long time. I am not sure if they are still about, but motors were made in Colchester Essex. They also had that same motor in some US coast Guard vessels back then.
I also sailed around the world on 130 ketch as engineer. That had Mercedes’ motors.
The first one I worked on and was engineer on was the second fastest yacht in the med at the time, worked on it 4 years approx. It was about 40 meters and had 2x 2,600 HP MTU motors. That was fun. Capable of about 40 - 50 knots if I remember right, The only faster one was Shergar. Owned by Aga Cann. That had 2 boing jet engines it it with turbine drives. It was capable of over 60 knots.
Also I worked on a huge schooner for a while, but had to leave due to problems.
It was good tax free money. I was always paid in USD tax free due to being offshore flags.
Funny old life! I was very happy to stop working at sea in the end.
