I guess what I'm asking is that the level of service you put in your boat or do you just sail it and if something breaks fix it?
IOW when was the last time you completely disassembled your steering system, Roller furling, electrical etc.
Yes I do ALL preventative maintenance. In the last 20 years my only failure has been a circuit breaker on a Universal diesel engine and a couple of manufacturer defects.
I prefer to sail when my wife and family are aboard rather than hold up in some remote anchorage rebuilding something that should have been done as routine. Something breaking at sea is a hazard to safety so I am not of the ilk to not fix anything and just let it break. I've been on a boat where we lost the rig during a delivery and it damn near killed a friend of mine. The owners response was "jeez the rigging is only 21 years old?" then tried to blame us for the rig failure..
