Oh that's a beauty and what a monster, I can't imagine that speed on water, 45 knots was the fastest I've been and that was quite quick enough for me.
Just imagine the sound - wonderful.
Funny you should mention that Rich, the most uncomfortable boat trip I ever experience was taking a power boat ( a Sealine I think) around the Isle of Wight at 45 knots. With the bows up and bouncing off the waves, it was not a pleasant experience.
The subsequent sail on a Nautor Swan 43 was far more my cup of tea.
