Re: Jon Boats?
The disadvantage of a jon boat is you have a shallow draft (the side of the boat isn't that far from the depth of the water). If I remember correctly, that jon boat is $550 and you were contemplating a trolling motor on the canoe - do you really need an outboard or can you get by with an electric for a total cost of $650 brand new?
On a 12 foot Jon, two people is enough with gear (fishing tackle, anchor, etc.). I wouldn't go over the recommended weight limit on any boat.
For $1,500 you have a lot of options if you take a look at the used market - you could even buy Jay's boat (if he hasn't sold it).
