Welcome aboard. There are a number of 60+ year old women living aboard
. Myself included.
As to type of boat
. A sailboat will in my mind, anyway be less expensive to operate. Smaller engines, cost less to maintain. My 34' sailboat gets 10-12 mpg on a good day. That is very good. A twin engine
powerboat has far more room, but fuel
mileage is 1.5 ish mpg. A cat has lots of room, but two engines and even slips cost more, in many places due to width.
If your planning to mainly stay in marina's with a few anchor
outs, a trawler
will give more space. A sailboat is pretty tight space wise, though I love my little boat.
