To be blunt, you have 25K to buy a 40's size boat with, do you have a grand a month to keep it?
I say that as I can't imagine a boat that size, for that price
, that didn't need a whole lot of work, it's going to cost $500 a month just to keep it in the shape it's in, in my opinion.
I'd say keep looking of course, but be saving all the while, then in two years you'll have 50K to buy that boat, and a 40's size boat at 50K is a whole different boat than a 40's size 25K boat.
But keep looking.
Sorry I turned 35 into 25 in my mind as You'll be amazed how fast 10K will disappear, taxes
and everything else.
