The 405 Flybridge is a Nimbus Coupé model built for knowledgeable boaters who enjoy social activities, comfortable living quarters, ease-of-handling and excellent long-distance cruising properties. The flybridge has been constructed to harmonize fully with the design of the new coupé series. The roof has light, sweeping lines and incorporates a folding mast. A large, fixed skylight makes the salon very light and airy despite the superstructure. The flybridge features several cleverly functional and social spaces. The flybridge includes a wet bar, with sink, grill and fridge, sun bed, large sofa and a twin helm seat. The twin seat can be turned 180 degrees and thus form a roomy social seating area in combination with the sofa. If desired, the sofa can be easily converted into an additional sun bed.

All functions on the flybridge have been designed to allow the boat to pass beneath bridges after a few simple adjustments. Thanks to the "sidewalk" deck layout, walking space is maximized on the starboard side, making it very easy to get on and off the boat and to spend time on deck, while allowing generous space in the cockpit and cabin. The Nimbus Coupé series has been built since 1969 and more than four thousand of these boats have been sold worldwide. The 405 Flybridge is built in Mariestad, Sweden at the Nimbus boatyard.
