Broker's Comments

There is not enough space for me to include all the comments that I would like to. In summary this is an outstandingly beautiful boat in first class condition in every respect. The amount of recent work done to her borders on the ridiculous, but it is all so well carried out, the boat just quietly says "I am the best of my kind". This is true, she has no equal. Still, you would expect this after spending well over a hundred grand on a boat in the last 18 months. See "more photos" to view 38 internal and external photos of this vessel.
