The Ft. Lauderdale boatshow was a good source of info where I visited the stand of NR Koeling which gave some very good advice.

Initially I had kind of figured out a system of Webasto (see my first post). Made in Germany so good stuff.  But, NR Koeling highly recommends systems from Climma (Italy), specially designed for maritime use while they added a few tricks of their own.

But, with the Euro/USD exchange rate going out of control,  I’ve also been looking for US-based hardware solutions and one good option seems to be Marine Air systems by Dometic.  Actually the mega yacht Perle Blue by Hakvoort actually has a Marine Air system which was designed by Heinen & Hopman, another great name in marine airco system design.

So,  the jury is still out on that.  It seems, however, that Marine Air has much smaller off-the-shelve fresh air handler units which may be very convenient in our situation where 2-3 of such fresh air units would solve a few issues.

So, still an open book.
