I'll second the opinions off Klaus and Ken, the F&C 44 is a beautiful boat and gets admiring comments everywhere she goes. I have owned ONYX, hull #23 since 2007 and have found the maintenance issues no worse and perhaps less than any other 30 year old boat, due in large part to the excellent maintenance from the PO. The biggest project so far was rewiring the shore power and replacing the DC panel with modern circuit breakers, not unusual in a boat of this age. The teak decks and varnished woodwork do take time to maintain but the results are worth it.
Klaus, I would like to hear from you on what was involved in moving the engine from the owners cabin to under the main companionway. I know later F&C 44's were built that way but it must be a tight fit.
