Hello Silvio
This had been up for sale for a few years and long admired her.
Given the size I think it's commercial license required and probably more of a business but wow. To keep it in that condition it would be probably best left that side of the world to crew and maintain her but again wow!
There is a video or two about on the construction which is interesting to watch for a very specialist skill these days.
For an unrealistic £100k id get the license but for 300k, is going to be for the one willing to take the challenge.
