For trailering, the Larson SEi 180 Sport 2005 has the edge at 2 365 lbs dry weight versus 2 375 lbs for the Larson 1850 LX 2010.

The Larson 1850 LX 2010 has a documented max rating of 190 hp. Engine specifications for the Larson SEi 180 Sport 2005 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 1850 LX 2010 is Coast Guard rated for 7 passengers, while the Larson SEi 180 Sport 2005 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: Which boat is wider, and does it affect trailering?

The Larson SEi 180 Sport 2005 measures 93" wide, compared to 88" for the Larson 1850 LX 2010. 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.

Q: How do the fuel tanks compare on the Larson 1850 LX 2010 and Larson SEi 180 Sport 2005?

Both boats carry similar fuel loads — 23 gallons and 23 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Larson 1850 LX 2010 and Larson SEi 180 Sport 2005 from the same manufacturer?

Yes — both the Larson 1850 LX 2010 and the Larson SEi 180 Sport 2005 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.
