When two boats share the same hull type — in this case both the Seaway Boats 24 Offshore 2013 and the Seaway Boats 24 Sportsman 2011 are deep vee designs with composite 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?
On paper these two are close siblings in the size department — Seaway Boats 24 Offshore 2013 at 24,0 ft versus Seaway Boats 24 Sportsman 2011 at 24,0 ft. Weight tells a clearer story for trailering families: the Seaway Boats 24 Offshore 2013 tips the scales at 395 lbs — 371 lbs more than the Seaway Boats 24 Sportsman 2011 at 24 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 175 hp, the Seaway Boats 24 Sportsman 2011 has a 45-hp advantage over the Seaway Boats 24 Offshore 2013's 130-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Seaway Boats 24 Sportsman 2011 carries 74 gallons versus 64 gallons in the Seaway Boats 24 Offshore 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 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: Performance buyers should lean toward the Seaway Boats 24 Sportsman 2011 and its 175-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Seaway Boats 24 Offshore 2013 with its 130-hp rating is the more economical daily driver.
