Both the Rinker 350 Express Cruiser 2008 and the Rinker 400 EC 2010 are modified-V designs, both built in fibreglass, so 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 400 EC 2010 measures 41,5 feet overall (2010), giving it roughly 4,5 additional feet of deck space compared to the Rinker 350 Express Cruiser 2008 at 37,0 feet (2008). Weight tells a clearer story for trailering families: the Rinker 400 EC 2010 tips the scales at 19 680 lbs - 4 130 lbs less than the Rinker 350 Express Cruiser 2008 at 15 550 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 Rinker 350 Express Cruiser 2008 carries a rated maximum of 375 hp. Engine data for the Rinker 400 EC 2010 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Rinker 400 EC 2010 carries 300 gallons versus 235 gallons in the Rinker 350 Express Cruiser 2008. 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 Rinker 400 EC 2010 is rated for 12 passengers, while the Rinker 350 Express Cruiser 2008 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker 400 EC 2010 could be the deciding factor.
