When two boats share the same hull type — in this case both the Larson Cabrio 370 Day Cruiser 2011 and the Larson LSR 2100 2013 are deep 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 370 Day Cruiser 2011 measures 36,9 feet overall (2011), giving it roughly 15,8 additional feet of deck space compared to the Larson LSR 2100 2013 at 21,1 feet (2013). Weight tells a clearer story for trailering families: the Larson Cabrio 370 Day Cruiser 2011 tips the scales at 168 lbs — 141 lbs more than the Larson LSR 2100 2013 at 27 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 Cabrio 370 Day Cruiser 2011 carries a rated maximum of 420 hp. Engine data for the Larson LSR 2100 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson Cabrio 370 Day Cruiser 2011 carries 266 gallons versus 3 gallons in the Larson LSR 2100 2013. 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 370 Day Cruiser 2011 is rated for 11 passengers, while the Larson LSR 2100 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Cabrio 370 Day Cruiser 2011 could be the deciding factor.
