Larson FX 1750 DC O/B 2012 vs Larson LSR 2100 2013 - Boat Spec Comparison

Q: Which is the larger boat - the Larson FX 1750 DC O/B 2012 or the Larson LSR 2100 2013?

The Larson LSR 2100 2013 is the longer of the two at 21,1 feet overall. The Larson FX 1750 DC O/B 2012 comes in at 17,4 feet, making it roughly 3,7 ft shorter - a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer - the Larson FX 1750 DC O/B 2012 or the Larson LSR 2100 2013?

For trailering, the Larson FX 1750 DC O/B 2012 has the edge at 1 700 lbs dry weight versus 2 700 lbs for the Larson LSR 2100 2013. 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.

Q: What is the maximum horsepower rating for these boats?

The Larson FX 1750 DC O/B 2012 has a documented max rating of 150 hp. Engine specifications for the Larson LSR 2100 2013 were not available in our database - check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Larson FX 1750 DC O/B 2012 is Coast Guard rated for 6 passengers, while the Larson LSR 2100 2013 is certified for 8. 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.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Larson FX 1750 DC O/B 2012 and Larson LSR 2100 2013 share an 8 ft. (2.44 m) beam - meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank - the Larson FX 1750 DC O/B 2012 or the Larson LSR 2100 2013?

The Larson LSR 2100 2013 has the bigger tank at 30 gallons, versus 23 gallons on the Larson FX 1750 DC O/B 2012. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson FX 1750 DC O/B 2012 and Larson LSR 2100 2013 from the same manufacturer?

Yes - both the Larson FX 1750 DC O/B 2012 and the Larson LSR 2100 2013 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.

Detailed Evaluation & Buyer Recommendation

Larson FX 1750 DC O/B 2012 vs Larson LSR 2100 2013: Same Brand, Different Boat

The Larson FX 1750 DC O/B 2012 is a modified-V design and the Larson LSR 2100 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Larson LSR 2100 2013 measures 21,1 feet overall (2013), giving it roughly 3,7 additional feet of deck space compared to the Larson FX 1750 DC O/B 2012 at 17,4 feet (2012). Weight tells a clearer story for trailering families: the Larson LSR 2100 2013 tips the scales at 2 700 lbs - 1 000 lbs less than the Larson FX 1750 DC O/B 2012 at 1 700 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 Larson FX 1750 DC O/B 2012 carries a rated maximum of 150 hp. Engine data for the Larson LSR 2100 2013 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson LSR 2100 2013 carries 30 gallons versus 23 gallons in the Larson FX 1750 DC O/B 2012. 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 LSR 2100 2013 is rated for 8 passengers, while the Larson FX 1750 DC O/B 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LSR 2100 2013 could be the deciding factor.

Bottom line: Choose the Larson LSR 2100 2013 if your priority is putting more people on the water - it handles 8 passengers and at 21,1 ft it has the deck room to back that rating up comfortably. The Larson FX 1750 DC O/B 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
