My wife-ish and I fall just under the line at 34 years old. We have a little Contessa 26 which doesn't have a home yet as we are about to make our way around 3 of the Great Lakes.
We were just at a little BBQ put on by some really nice folks in one marina. Outside of one other guy our age, everyone else was over 60. There were quite a few comments that young people just weren't interested any more. I put forth the notion that for sailing here you need money and time. Young people generally have one or the other but not both.
