Matching a deep vee Larson Cabrio 310 2011 against a modified vee Larson SEi 180 Ski Fish O/B 2006 means you're likely deciding between two genuinely 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 Cabrio 310 2011 measures 31,0 feet overall (2011), giving it roughly 14,0 additional feet of deck space compared to the Larson SEi 180 Ski Fish O/B 2006 at 17,0 feet (2006). At 104 lbs and 17 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 320 hp, the Larson Cabrio 310 2011 has a 170-hp advantage over the Larson SEi 180 Ski Fish O/B 2006's 150-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 SEi 180 Ski Fish O/B 2006 carries 23 gallons versus 16 gallons in the Larson Cabrio 310 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 Cabrio 310 2011 is rated for 9 passengers, while the Larson SEi 180 Ski Fish O/B 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 Cabrio 310 2011 could be the deciding factor.
