When two boats share the same hull type — in this case both the Kingfisher 1725 Flex TL 2013 and the Kingfisher 1825 Falcon TL 2013 are deep 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 — Kingfisher 1725 Flex TL 2013 at 17,5 ft versus Kingfisher 1825 Falcon TL 2013 at 18,0 ft. Weight tells a clearer story for trailering families: the Kingfisher 1725 Flex TL 2013 tips the scales at 143 lbs — 135 lbs more than the Kingfisher 1825 Falcon TL 2013 at 8 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 Kingfisher 1725 Flex TL 2013 carries a rated maximum of 90 hp. Engine data for the Kingfisher 1825 Falcon TL 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

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.
