When two boats share the same hull type — in this case both the Seaway Boats 24 Hardtop Sport 2012 and the Seaway Boats 27 Seafarer 2013 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?
The power gap is worth calling out. Rated to 220 hp, the Seaway Boats 27 Seafarer 2013 has a 105-hp advantage over the Seaway Boats 24 Hardtop Sport 2012's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Seaway Boats 27 Seafarer 2013 is rated for 8 passengers, while the Seaway Boats 24 Hardtop Sport 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Seaway Boats 27 Seafarer 2013 could be the deciding factor.
Bottom line: Choose the Seaway Boats 27 Seafarer 2013 if your priority is putting more people on the water — it handles 8 passengers and at 26,9 ft it has the deck room to back that rating up comfortably. The Seaway Boats 24 Hardtop Sport 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
