The Nimbus 405 Flybridge 2015 vs Nimbus Weekender 11 2023 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 Nimbus 405 Flybridge 2015 measures 43,9 feet overall (2015), giving it roughly 3,2 additional feet of deck space compared to the Nimbus Weekender 11 2023 at 40,7 feet (2023). Weight tells a clearer story for trailering families: the Nimbus 405 Flybridge 2015 tips the scales at 21 837 lbs — 9 492 lbs more than the Nimbus Weekender 11 2023 at 12 345 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 400 hp, the Nimbus Weekender 11 2023 has a 30-hp advantage over the Nimbus 405 Flybridge 2015's 370-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Nimbus 405 Flybridge 2015 carries 264 gallons versus 225 gallons in the Nimbus Weekender 11 2023. 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 Nimbus 405 Flybridge 2015 is rated for 13 passengers, while the Nimbus Weekender 11 2023 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nimbus 405 Flybridge 2015 could be the deciding factor.
Bottom line: Choose the Nimbus 405 Flybridge 2015 if your priority is putting more people on the water — it handles 13 passengers and at 43,9 ft it has the deck room to back that rating up comfortably. The Nimbus Weekender 11 2023 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
