When two boats share the same hull type — in this case both the Larson Cabrio 350 2009 and the Larson SEi 180 Fish Series 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 Cabrio 350 2009 measures 36,0 feet overall (2009), giving it roughly 19,0 additional feet of deck space compared to the Larson SEi 180 Fish Series I/O 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Larson SEi 180 Fish Series I/O 2006 tips the scales at 265 lbs — 251 lbs less than the Larson Cabrio 350 2009 at 14 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.
