Both the Boston Whaler 270 Vantage 2013 and the Boston Whaler 320 Outrage 2011 are deep-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 Boston Whaler 320 Outrage 2011 measures 32,2 feet overall (2011), giving it roughly 5,3 additional feet of deck space compared to the Boston Whaler 270 Vantage 2013 at 26,9 feet (2013). Weight tells a clearer story for trailering families: the Boston Whaler 320 Outrage 2011 tips the scales at 8 500 lbs - 3 300 lbs less than the Boston Whaler 270 Vantage 2013 at 5 200 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 power gap is worth calling out. Rated to 600 hp, the Boston Whaler 320 Outrage 2011 has a 150-hp advantage over the Boston Whaler 270 Vantage 2013's 450-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Boston Whaler 320 Outrage 2011 carries 300 gallons versus 175 gallons in the Boston Whaler 270 Vantage 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 Boston Whaler 320 Outrage 2011 is rated for 14 passengers, while the Boston Whaler 270 Vantage 2013 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 320 Outrage 2011 could be the deciding factor.
