Size is the most obvious dividing line here.

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the G3 Boats 1756 SC 2008 could be the deciding factor.
