When two boats share the same hull type — in this case both the Sessa Marine C 48 2012 and the Sessa Marine Fly 45 2012 are deep vee 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 Sessa Marine C 48 2012 measures 51,6 feet overall (2012), giving it roughly 4,8 additional feet of deck space compared to the Sessa Marine Fly 45 2012 at 46,8 feet (2012). Weight tells a clearer story for trailering families: the Sessa Marine Fly 45 2012 tips the scales at 31 967 lbs — 29 101 lbs less than the Sessa Marine C 48 2012 at 2 866 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 — 870 hp for the Sessa Marine C 48 2012 and 870 hp for the Sessa Marine Fly 45 2012. 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 — 168 gal and 168 gal — so range won't be a tiebreaker here.
Both boats are rated for 12 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 Sessa Marine C 48 2012 at 51,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sessa Marine Fly 45 2012 at 46,8 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.
