The Baja Marine 192 Islander 2005 vs Baja Marine 247 Islander 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Baja Marine 247 Islander 2012 measures 24,4 feet overall (2012), giving it roughly 5,4 additional feet of deck space compared to the Baja Marine 192 Islander 2005 at 19,0 feet (2005). Weight tells a clearer story for trailering families: the Baja Marine 192 Islander 2005 tips the scales at 291 lbs — 248 lbs more than the Baja Marine 247 Islander 2012 at 43 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 300 hp, the Baja Marine 247 Islander 2012 has a 40-hp advantage over the Baja Marine 192 Islander 2005's 260-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 192 Islander 2005 carries 37 gallons versus 8 gallons in the Baja Marine 247 Islander 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Baja Marine 247 Islander 2012 at 24,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Baja Marine 192 Islander 2005 at 19,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
