Re: Are Boats Built in the 70's Just Too Tired
Dont know the name he gives it, but calder explains in his maintanance book the effect of having a boat full of new systems. (refitted or new). After some initial issues it will have a problem free period and then when many of the systems get to the end of their live expectancy, you get lots of problems at once. For this reason he suggest it may be better to do steady maintanance instead of refitting a whole boat all at once.
I can immagine this is what people mean with the boats from the 70s where the engine, rigging, sails, electrical wiring and whatever may not yet have been replaced and all come to the end of their live expectancy now.
If however things are replaced on a regular basis, and everything is on a different point in its lifecycle, you should just have an old boat that needs maintanance. This effectively means you will be replacing one of these major things every few years and thus spend some 1000s per year for this maintanance. If you can do part of this yourself and part of it in cheap labor countries, this is still nothing compared to the write-off on the value of buying a (relatively) new boat. If you keep doing the maintenance, it seems to me that it should last for another century as long as it doesnt run into hurricanes or other major disasters.
