When two boats share the same hull type — in this case both the Parti Kraft PK2180 RE-3 Gate 2007 and the Parti Kraft PK2186 DF 2007 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 — Parti Kraft PK2180 RE-3 Gate 2007 at 21,0 ft versus Parti Kraft PK2186 DF 2007 at 21,0 ft. Weight tells a clearer story for trailering families: the Parti Kraft PK2180 RE-3 Gate 2007 tips the scales at 1 619 lbs — 104 lbs more than the Parti Kraft PK2186 DF 2007 at 1 515 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 115 hp, the Parti Kraft PK2186 DF 2007 has a 25-hp advantage over the Parti Kraft PK2180 RE-3 Gate 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.
Both boats are rated for 1 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 Parti Kraft PK2186 DF 2007 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Parti Kraft PK2180 RE-3 Gate 2007 with its 90-hp rating is the more economical daily driver.
