I vote this for the understatement of the year! Looks like beautiful work professionally done with no skimping on $$. I just remembered when I showed Marmot your boat and the only thing he didn't like was the ac black foam rubber insulation. Bet your new ac would bring him a thumbs up. I know this seems trivial for the scope of work you've shown us, but I like the new salon lamp. I see fingerprints from Charlie's Loocker.[/QUOTE] If the builder did the air conditioning install properly in the first place, there would be no reason that the OP would be doing any of this work on a 7 year old boat, nor spending a huge expense, nor tearing the entire interior apart, nor a huge waste of his time. All of the air conditioning should have been working 100% on a 7 year old yacht.
