Q: Which is the larger boat — the Larson LXi 288 I/O 2011 or the Larson SEi 180 Ski Fish I/O 2006?

The Larson LXi 288 I/O 2011 is the longer of the two at 29,2 feet overall. The Larson SEi 180 Ski Fish I/O 2006 comes in at 17,0 feet, making it roughly 12,2 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Larson LXi 288 I/O 2011 or the Larson SEi 180 Ski Fish I/O 2006?

For trailering, the Larson SEi 180 Ski Fish I/O 2006 has the edge at 265 lbs dry weight versus 597 lbs for the Larson LXi 288 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.

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

The Larson LXi 288 I/O 2011 has a documented max rating of 430 hp. Engine specifications for the Larson SEi 180 Ski Fish I/O 2006 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 LXi 288 I/O 2011 is Coast Guard rated for 8 passengers, while the Larson SEi 180 Ski Fish I/O 2006 is certified for 6. 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 LXi 288 I/O 2011 measures 108" wide, compared to 93" for the Larson SEi 180 Ski Fish I/O 2006. 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 LXi 288 I/O 2011 or the Larson SEi 180 Ski Fish I/O 2006?

The Larson SEi 180 Ski Fish I/O 2006 has the bigger tank at 23 gallons, versus 1 gallons on the Larson LXi 288 I/O 2011. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson LXi 288 I/O 2011 and Larson SEi 180 Ski Fish I/O 2006 from the same manufacturer?

Yes — both the Larson LXi 288 I/O 2011 and the Larson SEi 180 Ski Fish I/O 2006 are built by Larson. That means shared dealer networks, common parts availability, and consistent build quality across the line.

Detailed Evaluation & Buyer Recommendation

Larson LXi 288 I/O 2011 vs Larson SEi 180 Ski Fish I/O 2006 — Which Modified Vee Fits Your Needs?

When two boats share the same hull type — in this case both the Larson LXi 288 I/O 2011 and the Larson SEi 180 Ski Fish I/O 2006 are modified vee designs with fiberglass 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?

Size is the most obvious dividing line here. The Larson LXi 288 I/O 2011 measures 29,2 feet overall (2011), giving it roughly 12,2 additional feet of deck space compared to the Larson SEi 180 Ski Fish I/O 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Larson LXi 288 I/O 2011 tips the scales at 597 lbs — 332 lbs more than the Larson SEi 180 Ski Fish I/O 2006 at 265 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 LXi 288 I/O 2011 carries a rated maximum of 430 hp. Engine data for the Larson SEi 180 Ski Fish I/O 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson SEi 180 Ski Fish I/O 2006 carries 23 gallons versus 1 gallons in the Larson LXi 288 I/O 2011. 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 LXi 288 I/O 2011 is rated for 8 passengers, while the Larson SEi 180 Ski Fish I/O 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 288 I/O 2011 could be the deciding factor.

Bottom line: Choose the Larson LXi 288 I/O 2011 if your priority is putting more people on the water — it handles 8 passengers and at 29,2 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 Ski Fish I/O 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
