When two boats share the same hull type — in this case both the Landau Atlantis Sport Cruise 230 2011 and the Landau Signature Series 2700 2011 are pontoon designs with aluminum 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?
Size is the most obvious dividing line here. The Landau Signature Series 2700 2011 measures 27,0 feet overall (2011), giving it roughly 4,0 additional feet of deck space compared to the Landau Atlantis Sport Cruise 230 2011 at 23,0 feet (2011). Weight tells a clearer story for trailering families: the Landau Signature Series 2700 2011 tips the scales at 2 855 lbs — 2 621 lbs less than the Landau Atlantis Sport Cruise 230 2011 at 234 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.
Both boats share a closely matched power ceiling — 130 hp for the Landau Atlantis Sport Cruise 230 2011 and 130 hp for the Landau Signature Series 2700 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 26 gal and 26 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Landau Signature Series 2700 2011 is rated for 14 passengers, while the Landau Atlantis Sport Cruise 230 2011 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Landau Signature Series 2700 2011 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 23 aluminum tubes at 21" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: Choose the Landau Signature Series 2700 2011 if your priority is putting more people on the water — it handles 14 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Landau Atlantis Sport Cruise 230 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
