Larson FX 1850 DC O/B 2012 vs Larson LX 710 I/O 2011 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Larson FX 1850 DC O/B 2012 and the Larson LX 710 I/O 2011 are modified 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 1850 DC O/B 2012 at 18,5 ft versus Larson LX 710 I/O 2011 at 17,1 ft. At 182 lbs and 204 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 175 hp, the Larson FX 1850 DC O/B 2012 has a 40-hp advantage over the Larson LX 710 I/O 2011's 135-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 1850 DC O/B 2012 carries 35 gallons versus 23 gallons in the Larson LX 710 I/O 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 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.

Bottom line: Performance buyers should lean toward the Larson FX 1850 DC O/B 2012 and its 175-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Larson LX 710 I/O 2011 with its 135-hp rating is the more economical daily driver.

Larson FX 1850 DC O/B 2012 vs Larson LX 710 I/O 2011 — Common Questions

Which is the larger boat — the Larson FX 1850 DC O/B 2012 or the Larson LX 710 I/O 2011?
The Larson FX 1850 DC O/B 2012 is the longer of the two at 18,5 feet overall. The Larson LX 710 I/O 2011 comes in at 17,1 feet, making it roughly 1,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Larson FX 1850 DC O/B 2012 or the Larson LX 710 I/O 2011?
For trailering, the Larson FX 1850 DC O/B 2012 has the edge at 182 lbs dry weight versus 204 lbs for the Larson LX 710 I/O 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Larson FX 1850 DC O/B 2012 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Larson LX 710 I/O 2011 tops out at 135 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Larson FX 1850 DC O/B 2012 is Coast Guard rated for 7 passengers, while the Larson LX 710 I/O 2011 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Larson FX 1850 DC O/B 2012 measures 92" wide, compared to 88" for the Larson LX 710 I/O 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Larson FX 1850 DC O/B 2012 or the Larson LX 710 I/O 2011?
The Larson FX 1850 DC O/B 2012 has the bigger tank at 35 gallons, versus 23 gallons on the Larson LX 710 I/O 2011. That 12-gallon difference translates to roughly 36–60 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson FX 1850 DC O/B 2012 and Larson LX 710 I/O 2011 from the same manufacturer?
Yes — both the Larson FX 1850 DC O/B 2012 and the Larson LX 710 I/O 2011 are built by Larson. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
