The Astondoa 40 Open 2001 vs Astondoa AS5 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.
The power gap is worth calling out. Rated to 725 hp, the Astondoa AS5 2021 has a 415-hp advantage over the Astondoa 40 Open 2001's 310-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Astondoa AS5 2021 carries 634 gallons versus 206 gallons in the Astondoa 40 Open 2001. 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 Astondoa AS5 2021 is rated for 17 passengers, while the Astondoa 40 Open 2001 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Astondoa AS5 2021 could be the deciding factor.
Bottom line: Choose the Astondoa AS5 2021 if your priority is putting more people on the water — it handles 17 passengers and at 56,9 ft it has the deck room to back that rating up comfortably. The Astondoa 40 Open 2001 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
