I feel some older boats are better than new. Others are 10 years or so behind in maintenance and these would be a major commitment beyond the normal commitment of boat ownership
I think of boat care as a list of equipment that each has it's own duty cycle. At some point each thing needs to be replaced. If you get a new boat, all the duty cycles are starting at zero. If you get a used boat, everything is at various points in the duty cycle. Assuming the boat was well cared for, you just have to pick up the process and do whatever is next.
