Detailed Evaluation & Buyer Recommendation
Ocean Alexander 52 Sedan 2008 vs Ocean Alexander 78 Motoryacht 2008 — Which Semi Displacement Fits Your Needs?
When two boats share the same hull type — in this case both the Ocean Alexander 52 Sedan 2008 and the Ocean Alexander 78 Motoryacht 2008 are semi displacement 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?
Size is the most obvious dividing line here. The Ocean Alexander 78 Motoryacht 2008 measures 78,0 feet overall (2008), giving it roughly 26,0 additional feet of deck space compared to the Ocean Alexander 52 Sedan 2008 at 52,0 feet (2008). Weight tells a clearer story for trailering families: the Ocean Alexander 78 Motoryacht 2008 tips the scales at 160 892 lbs — 160 856 lbs less than the Ocean Alexander 52 Sedan 2008 at 36 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.
For family outings this is probably the sharpest distinction between the two. The Ocean Alexander 78 Motoryacht 2008 is rated for 23 passengers, while the Ocean Alexander 52 Sedan 2008 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ocean Alexander 78 Motoryacht 2008 could be the deciding factor.
Bottom line: Choose the Ocean Alexander 78 Motoryacht 2008 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 52 Sedan 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 15 that costs less to run day-to-day.
