For trailering, the Larson SEi 180 Ski Fish 2009 has the edge at 2 650 lbs dry weight versus 2 700 lbs for the Larson Senza 186 2005.

The Larson SEi 180 Ski Fish 2009 is Coast Guard rated for 6 passengers, while the Larson Senza 186 2005 is certified for 9. 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 Senza 186 2005 measures 94" wide, compared to 93" for the Larson SEi 180 Ski Fish 2009. 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: Which boat has the larger fuel tank - the Larson SEi 180 Ski Fish 2009 or the Larson Senza 186 2005?

The Larson Senza 186 2005 has the bigger tank at 29 gallons, versus 23 gallons on the Larson SEi 180 Ski Fish 2009. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson SEi 180 Ski Fish 2009 and Larson Senza 186 2005 from the same manufacturer?

Yes - both the Larson SEi 180 Ski Fish 2009 and the Larson Senza 186 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.
