I'm on their mailing list too, seemingly after my first tour of a Nordhaven 15 years ago at the Southampton Boat Show - they have long memories!
I was impressed with the build quality and comfort and the fact that it's sort of affordable as far as running costs go. Instead of twin 370 hp engines that typical day runabouts have and capable of 40 knots (my brother has one), these plodders have single (usually I believe) big lazy engines that sip fuel rather more considerately. This gives them a huge range, high reliability and low running costs - just the job for an explorer type of vessel for those wanting to cast off, travel hundreds of miles and explore.
Although I've visited Nordhavens, I eventually convinced myself that I prefer to see land rather than sea, so opted for an inland waterways motor cruiser that offers similar benefits of low costs and good accommodation, but finding overnight moorings is easy and weather becomes nothing more than a mild inconvenience. The best thing though is that you are never more than a few feet from land and this changes by the minute - rather different from sea travel. This inland waterways lifestyle is probably more difficult to find in the US than Europe where I travel. It surprised me how many Americans (and Canadians, Aussies and Kiwis) that I encounter on these canals, rivers and lakes.
For a cost effective vessel for prolonged distance or time travel at sea, I’d seriously look Nordhaven or perhaps Trader.
