Check out this show. There should be a bunch there to look at and to touch.

If you fish the Ottawa you know the river can get nasty at times, so can the St. Lawrence.
But if you fish the smaller ? so measure your garage and get the biggest that will fit. Trailer and boat. Look for a swing away trailer.
More questions, do you want a kicker motor and a bow mount trolling motor ? Fish finders, full roof, heaters.
Insurance, boaters licence ?
Good luck.
