When two boats share the same hull type — in this case both the Gillgetter 615 Fish N Cruise 2011 and the Gillgetter 713 Fish N Cruise 2013 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Gillgetter 615 Fish N Cruise 2011 at 15,3 ft versus Gillgetter 713 Fish N Cruise 2013 at 13,5 ft. Weight tells a clearer story for trailering families: the Gillgetter 615 Fish N Cruise 2011 tips the scales at 825 lbs — 730 lbs more than the Gillgetter 713 Fish N Cruise 2013 at 95 lbs. 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.

Both boats share a closely matched power ceiling — 25 hp for the Gillgetter 615 Fish N Cruise 2011 and 30 hp for the Gillgetter 713 Fish N Cruise 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Gillgetter 713 Fish N Cruise 2013 comes in at 3 lbs per hp versus 33 lbs per hp for the Gillgetter 615 Fish N Cruise 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
