When two boats share the same hull type — in this case both the Rinker 370 Express Cruiser 2008 and the Rinker 380 Express Cruiser 2009 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 Rinker 380 Express Cruiser 2009 measures 39,0 feet overall (2009), giving it roughly 35,0 additional feet of deck space compared to the Rinker 370 Express Cruiser 2008 at 4,0 feet (2008). At 184 lbs and 184 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 Rinker 370 Express Cruiser 2008 carries a rated maximum of 375 hp. Engine data for the Rinker 380 Express Cruiser 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 235 gal and 235 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Rinker 370 Express Cruiser 2008 is rated for 12 passengers, while the Rinker 380 Express Cruiser 2009 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker 370 Express Cruiser 2008 could be the deciding factor.
