Both the Crownline 270 BR 2010 and the Crownline 315 SCR 2009 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 Crownline 315 SCR 2009 measures 32,0 feet overall (2009), giving it roughly 3,8 additional feet of deck space compared to the Crownline 270 BR 2010 at 28,3 feet (2010). Weight tells a clearer story for trailering families: the Crownline 315 SCR 2009 tips the scales at 11 000 lbs - 5 500 lbs less than the Crownline 270 BR 2010 at 5 500 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 750 hp, the Crownline 315 SCR 2009 has a 325-hp advantage over the Crownline 270 BR 2010's 425-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crownline 315 SCR 2009 carries 139 gallons versus 84 gallons in the Crownline 270 BR 2010. 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 Crownline 315 SCR 2009 is rated for 9 passengers, while the Crownline 270 BR 2010 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 315 SCR 2009 could be the deciding factor.
