The current one is the largest and the oldest bought. She needs a little paint, some upgrade equipment. No more work than any older fiberglass boat. Each boat differed in construction and maintenance history. There isn't a single soft spot on Wandering Star, I aim to keep it that way. It won't be hard, because she's not dead or even sick.
That's been my experience. If you're not playing "catch up" the work is light and easily done.
