Hi there! There are a ton of threads on suitable boats here. Not to sound too obvious but in the search menu there is a special Google
search that performs like google
but right here in CF.
I think you are also fortunate in that you are already near the water
so you should be able to get out a kick a few tires.
60-65k might be tight for 4 people and a dog but definitely not beyond impossible.
What kind of boats have you been looking at?
