The vessel itself is smaller - both in height and width - compared to what I expected, but it is spectacular. A bit gimicky, I think but very unusual. They should paint if black and hire it out for the next Batman movie - it would make an ideal Batm'boat. Or, alternatively, for the next James Bond movie.
I shudder to think how I would go in it on a long voyage - very cramped inside. I imagine it would get swealtering down below in warmer weather.
Notwithstanding all the above, a very worthwhile visit as it is certainly something "different".
