The Fiart Mare P54 2024 vs Fiart Mare Seawalker 39 Seawalk 2021 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.
Size is the most obvious dividing line here. The Fiart Mare P54 2024 measures 54,8 feet overall (2024), giving it roughly 13,3 additional feet of deck space compared to the Fiart Mare Seawalker 39 Seawalk 2021 at 41,5 feet (2021). Weight tells a clearer story for trailering families: the Fiart Mare P54 2024 tips the scales at 44 093 lbs — 26 677 lbs more than the Fiart Mare Seawalker 39 Seawalk 2021 at 17 416 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 725 hp, the Fiart Mare P54 2024 has a 405-hp advantage over the Fiart Mare Seawalker 39 Seawalk 2021's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Fiart Mare P54 2024 carries 766 gallons versus 248 gallons in the Fiart Mare Seawalker 39 Seawalk 2021. 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 Fiart Mare P54 2024 is rated for 16 passengers, while the Fiart Mare Seawalker 39 Seawalk 2021 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fiart Mare P54 2024 could be the deciding factor.
Bottom line: Choose the Fiart Mare P54 2024 if your priority is putting more people on the water — it handles 16 passengers and at 54,8 ft it has the deck room to back that rating up comfortably. The Fiart Mare Seawalker 39 Seawalk 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
