When two boats share the same hull type — in this case both the Sessa Marine C 38 2012 and the Sessa Marine Fly 45 2013 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 Fly 45 2013 measures 46,8 feet overall (2013), giving it roughly 8,4 additional feet of deck space compared to the Sessa Marine C 38 2012 at 38,3 feet (2012). Weight tells a clearer story for trailering families: the Sessa Marine Fly 45 2013 tips the scales at 31 967 lbs — 14 331 lbs less than the Sessa Marine C 38 2012 at 17 636 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.

The power gap is worth calling out. Rated to 870 hp, the Sessa Marine Fly 45 2013 has a 270-hp advantage over the Sessa Marine C 38 2012's 600-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sessa Marine Fly 45 2013 carries 168 gallons versus 127 gallons in the Sessa Marine C 38 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.
