The Haines Marine 36 Sedan Sedan 2024 vs Haines Marine 400 2024 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
The power gap is worth calling out. Rated to 320 hp, the Haines Marine 400 2024 has a 261-hp advantage over the Haines Marine 36 Sedan Sedan 2024's 59-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Haines Marine 400 2024 carries 22 gallons versus 8 gallons in the Haines Marine 36 Sedan Sedan 2024. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Haines Marine 400 2024 is rated for 12 passengers, while the Haines Marine 36 Sedan Sedan 2024 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Haines Marine 400 2024 could be the deciding factor.
Bottom line: Choose the Haines Marine 400 2024 if your priority is putting more people on the water — it handles 12 passengers and at 40,0 ft it has the deck room to back that rating up comfortably. The Haines Marine 36 Sedan Sedan 2024 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
