When two boats share the same hull type — in this case both the Gulf Stream Boats 270CC 2011 and the Gulf Stream Boats 290CC 2012 are catamaran designs with fiberglass construction — 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?
On paper these two are close siblings in the size department — Gulf Stream Boats 270CC 2011 at 27,0 ft versus Gulf Stream Boats 290CC 2012 at 29,1 ft. At 445 lbs and 445 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 500 hp, the Gulf Stream Boats 290CC 2012 has a 50-hp advantage over the Gulf Stream Boats 270CC 2011's 450-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 252 gal and 252 gal — so range won't be a tiebreaker here.
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 Gulf Stream Boats 290CC 2012 at 29,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Gulf Stream Boats 270CC 2011 at 27,0 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.
