Nearly 30 years old and still looks like 10, she'll likely outlast us unless something untoward occurs..
How long for us? As long as we can afford her, I suppose (got a nasty moorage increase notice this week....) but she's the right size for the two of us as long as we're fit. Unlikely we'll upgrade - we're on our way down from 40 feet - unless some long lost relative leaves us something unexpected...
As to the stinkpot.... maybe one day but not something fast, that's for sure. I'd prefer to think not, but on the water somehow would be better than not.
