Both the Baja Marine 277 Islander 2012 and the Baja Marine 335 Performance 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 Baja Marine 335 Performance 2009 measures 31,0 feet overall (2009), giving it roughly 3,6 additional feet of deck space compared to the Baja Marine 277 Islander 2012 at 27,4 feet (2012). Weight tells a clearer story for trailering families: the Baja Marine 335 Performance 2009 tips the scales at 8 000 lbs - 2 900 lbs less than the Baja Marine 277 Islander 2012 at 5 100 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 525 hp, the Baja Marine 335 Performance 2009 has a 205-hp advantage over the Baja Marine 277 Islander 2012's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Baja Marine 335 Performance 2009 carries 190 gallons versus 101 gallons in the Baja Marine 277 Islander 2012. 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 Baja Marine 277 Islander 2012 is rated for 10 passengers, while the Baja Marine 335 Performance 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Baja Marine 277 Islander 2012 could be the deciding factor.
Bottom line: Choose the Baja Marine 277 Islander 2012 if your priority is putting more people on the water - it handles 10 passengers and at 27,4 ft it has the deck room to back that rating up comfortably. The Baja Marine 335 Performance 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
