This boat is truly something. However, it certainly is not a mum and dad cruiser. It is just too much.
When travelling
Europe folk would say, when showing us around “The consort(s) of King ….. and his chancellor stayed here while visiting their estates in 15... “ In other words, anything so lavish has a history/provenance that may appeal to the wealthy or those who have higher aspirations (earned or not). So maybe you could espouse some similar feature to the boat’s glorious past. In today’s milieu you could mention rock’n roll stars, drug lords or some other hedonistic infamous characters.
To me (and my tub is a very basic 16 m ketch) your boat obviously has had a few small fortunes thrown at it and just sheer
maintenance would be beyond the average
income. You need to appeal to someone or maybe even a consortium (e.g. a group of business
men who could collectively manage the costs) that could see themselves swanning around on such a glamorous vessel. Or impressing their acquaintances/mistresses.
The suggestion that the boat be presented at boat shows seems to be the way to go. Advertise in the appropriate journals such as business or high-end lifestyle magazines. Have you approached
charter companies? They just may have a demand for specialist lavish vessels or at least they may inform you of possibilities and the market for such a boat.
