Both the FinCraft 17 DC 2009 and the FinCraft 1850 DC 2011 are modified-V designs, both built in fibreglass, 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 - FinCraft 17 DC 2009 at 16,9 ft versus FinCraft 1850 DC 2011 at 18,5 ft. Weight tells a clearer story for trailering families: the FinCraft 1850 DC 2011 tips the scales at 1 820 lbs - 370 lbs less than the FinCraft 17 DC 2009 at 1 450 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 175 hp, the FinCraft 1850 DC 2011 has a 60-hp advantage over the FinCraft 17 DC 2009'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 FinCraft 1850 DC 2011 carries 35 gallons versus 23 gallons in the FinCraft 17 DC 2009. 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 FinCraft 1850 DC 2011 is rated for 7 passengers, while the FinCraft 17 DC 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the FinCraft 1850 DC 2011 could be the deciding factor.
Bottom line: Choose the FinCraft 1850 DC 2011 if your priority is putting more people on the water - it handles 7 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The FinCraft 17 DC 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
