Detailed Evaluation & Buyer Recommendation
Ocean Alexander 70E 2017 vs Ocean Alexander 78 Motoryacht 2007 — Same Brand, Different Boat
The Ocean Alexander 70E 2017 vs Ocean Alexander 78 Motoryacht 2007 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.
The Ocean Alexander 70E 2017 carries a rated maximum of 1 200 hp. Engine data for the Ocean Alexander 78 Motoryacht 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Ocean Alexander 70E 2017 carries 104 gallons versus 23 gallons in the Ocean Alexander 78 Motoryacht 2007. 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 Ocean Alexander 78 Motoryacht 2007 is rated for 23 passengers, while the Ocean Alexander 70E 2017 caps at 21. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ocean Alexander 78 Motoryacht 2007 could be the deciding factor.
Bottom line: Choose the Ocean Alexander 78 Motoryacht 2007 if your priority is putting more people on the water — it handles 23 passengers and at 78,0 ft it has the deck room to back that rating up comfortably. The Ocean Alexander 70E 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 21 that costs less to run day-to-day.
