When two boats share the same hull type — in this case both the Phoenix Boats 618 Pro 2011 and the Phoenix Boats 719 ProXP 2012 are modified vee 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 — Phoenix Boats 618 Pro 2011 at 18,5 ft versus Phoenix Boats 719 ProXP 2012 at 19,7 ft. Weight tells a clearer story for trailering families: the Phoenix Boats 719 ProXP 2012 tips the scales at 175 lbs — 160 lbs less than the Phoenix Boats 618 Pro 2011 at 15 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.
The power gap is worth calling out. Rated to 150 hp, the Phoenix Boats 719 ProXP 2012 has a 35-hp advantage over the Phoenix Boats 618 Pro 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Phoenix Boats 618 Pro 2011 carries 36 gallons versus 4 gallons in the Phoenix Boats 719 ProXP 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 5 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.
Bottom line: Performance buyers should lean toward the Phoenix Boats 719 ProXP 2012 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Phoenix Boats 618 Pro 2011 with its 115-hp rating is the more economical daily driver.
