The Kingfisher 1775 Extreme Duty 2013 is a deep-V design and the Kingfisher 1825 Trio Side Console 2012 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Kingfisher 1775 Extreme Duty 2013 at 17,7 ft versus Kingfisher 1825 Trio Side Console 2012 at 17,7 ft. Weight tells a clearer story for trailering families: the Kingfisher 1775 Extreme Duty 2013 tips the scales at 2 281 lbs - 1 181 lbs more than the Kingfisher 1825 Trio Side Console 2012 at 1 100 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 200 hp, the Kingfisher 1775 Extreme Duty 2013 has a 85-hp advantage over the Kingfisher 1825 Trio Side Console 2012'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 Kingfisher 1775 Extreme Duty 2013 carries 36 gallons versus 20 gallons in the Kingfisher 1825 Trio Side Console 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Kingfisher 1825 Trio Side Console 2012 comes in at 10 lbs per hp versus 11 lbs per hp for the Kingfisher 1775 Extreme Duty 2013. 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.
Bottom line: Performance buyers should lean toward the Kingfisher 1775 Extreme Duty 2013 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Kingfisher 1825 Trio Side Console 2012 with its 115-hp rating is the more economical daily driver.
