Both the Sedona F 19 2008 and the Sedona LC 21 2008 are pontoon designs, both built in aluminium, so 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 - Sedona F 19 2008 at 18,0 ft versus Sedona LC 21 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Sedona LC 21 2008 tips the scales at 1 670 lbs - 134 lbs less than the Sedona F 19 2008 at 1 536 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 90 hp, the Sedona LC 21 2008 has a 30-hp advantage over the Sedona F 19 2008's 60-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sedona LC 21 2008 carries 26 gallons versus 15 gallons in the Sedona F 19 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sedona LC 21 2008 is rated for 9 passengers, while the Sedona F 19 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sedona LC 21 2008 could be the deciding factor.
Bottom line: Choose the Sedona LC 21 2008 if your priority is putting more people on the water - it handles 9 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Sedona F 19 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
