When two boats share the same hull type — in this case both the Larson FX 1750 SC O/B 2013 and the Larson FX 1850 DC O/B 2013 are deep vee designs with composite 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 — Larson FX 1750 SC O/B 2013 at 17,4 ft versus Larson FX 1850 DC O/B 2013 at 18,5 ft. Weight tells a clearer story for trailering families: the Larson FX 1850 DC O/B 2013 tips the scales at 2 219 lbs — 220 lbs less than the Larson FX 1750 SC O/B 2013 at 1 999 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 Larson FX 1850 DC O/B 2013 has a 25-hp advantage over the Larson FX 1750 SC O/B 2013's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson FX 1750 SC O/B 2013 carries 22 gallons versus 3 gallons in the Larson FX 1850 DC O/B 2013. 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 Larson FX 1850 DC O/B 2013 is rated for 7 passengers, while the Larson FX 1750 SC O/B 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson FX 1850 DC O/B 2013 could be the deciding factor.
