Cobra Ribs Navis N40 2024 vs Cobra Ribs Patronus 5.6 2020 — Same Brand, Different Boat

The Cobra Ribs Navis N40 2024 vs Cobra Ribs Patronus 5.6 2020 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 500 hp, the Cobra Ribs Navis N40 2024 has a 330-hp advantage over the Cobra Ribs Patronus 5.6 2020's 170-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 Cobra Ribs Navis N40 2024 is rated for 11 passengers, while the Cobra Ribs Patronus 5.6 2020 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobra Ribs Navis N40 2024 could be the deciding factor.

Bottom line: Choose the Cobra Ribs Navis N40 2024 if your priority is putting more people on the water — it handles 11 passengers and at 39,3 ft it has the deck room to back that rating up comfortably. The Cobra Ribs Patronus 5.6 2020 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
