Detailed Chronology: From Heritage Concept to Cannes Debut
To understand the trajectory that led to the creation of the Sport Weekender 42 Open, one must look backward through the rich archives of Nimbus Boats before tracing the precise development timeline that brought this vessel to the waters of the French Riviera.
The Historic Precedent: The Spirit of the 32 Ballista
The design DNA of the new Sport Weekender 42 Open does not spring from a vacuum. Nimbus designers drew heavy inspiration from one of the most iconic vessels in the yard’s modern history: the Nimbus 32 Ballista. Manufactured between 1990 and 2005, the Ballista was celebrated as an uncompromising, high-performance daycruiser capable of cruising effortlessly at 40 knots.
The defining structural signature of the Ballista was its raked, purposeful targa arch—a feature that served both an aesthetic and a practical purpose, providing structural rigidity, mounting points for navigation electronics and canvas work, and a distinctively aggressive stance on the water. Over two decades later, as modern boaters increasingly demand flexible, customizable deck layouts without sacrificing high-speed capability, Nimbus leadership recognized an opportunity to reinterpret the classic targa aesthetic for a new generation.
The Evolution of the 42 Platform
The baseline Sport Weekender 42 (SW42) was originally conceived as a hardtop cruiser designed to offer shelter from the unpredictable and often unforgiving weather of Northern European waters. While the traditional T-top variant achieved immense commercial success for its all-weather livability, a vocal segment of the global market—particularly buyers cruising the Mediterranean, the Caribbean, and sun-drenched coastal waters—signaled a strong preference for a truly open-air layout.
Rather than designing an entirely new hull from scratch, Nimbus engineers embarked on a top-side re-engineering initiative. The primary objective was to strip away the heavy composite hardtop and glass enclosure panels, replacing them with a lighter, lower-profile targa arch system. This structural shift required recalculating the vessel’s center of gravity, redesigning the canvas and bimini deployment mechanisms, and re-engineering the windshield profile to ensure wind deflection remained optimal for helm operators traveling at high velocities.
The Cannes Yachting Festival Global Reveal
The culmination of this rigorous development cycle occurred at the Cannes Yachting Festival, widely regarded as Europe’s premier in-water boat show. Positioned prominently among the industry’s elite dayboats and luxury tenders, the Sport Weekender 42 Open captured immediate attention from marine journalists, prospective buyers, and industry peers alike. The debut served not only as a showcase for Scandinavian craftsmanship but also as a definitive statement regarding the future design language of Nimbus’s Sport series.
Architectural Nuances, Deck Layout, and Interior Accommodations
While the removal of the hardtop is the most visually striking alteration, the genius of the Sport Weekender 42 Open lies in how the remaining deck space and interior volumes have been optimized for versatility and luxury living.

At the structural heart of the Open variant is the fixed glass-fiber targa arch. Unlike fabric biminis that can flutter and fail at high speeds, or heavy structural hardtops that raise the vessel’s vertical center of gravity, the targa arch provides a rock-solid structural anchor point.
The arch serves multiple operational roles:
- The Canvas Ecosystem: It acts as the central hub for a modular canopy system. Owners can configure the vessel to be fully covered, partially shaded, or completely open depending on immediate meteorological conditions.
- Lighting and Electronics: It houses integrated LED courtesy lighting, searchlights, radar arrays, and antenna arrays, keeping the deck clean and uncluttered.
- Aesthetic Anchoring: Visually, the arch sweeps backward at a dynamic angle, visually compressing the cabin profile and granting the 41-footer the aggressive, forward-leaning stance of a high-end sportscar.
Flexible Deck Living and the Folding Side Balcony
True to its "Weekender" moniker, the deck layout is engineered around open-air socialization and effortless entertaining. The aft cockpit features a modular lounge area that can be converted from a sun pad into an alfresco dining space within minutes.
A standout feature retained from the hardtop model is the folding side balcony. When deployed at anchor, this hydraulic starboard bulwark flips outward, dramatically increasing the usable deck beam and creating a seamless, over-the-water platform for swimming, diving, or simply enjoying a sunset cocktail. The connection between the cockpit, the wet bar, and the swim platform is entirely unobstructed, facilitating natural traffic flow during social gatherings.
Lower Deck Accommodations
Despite its sleek, low-profile exterior lines, the Sport Weekender 42 Open defies expectations regarding interior volume. Below deck, the vessel offers sophisticated, high-end accommodations capable of sleeping four guests comfortably across two distinct double cabins.
- The Forward Master Cabin: Features a spacious centerline berth, ample hull-side windows that flood the space with natural light, and generous storage lockers.
- The Midships Guest Cabin: Offers an optimized twin-or-double berth configuration, perfect for children or accompanying guests.
- The Head Compartment: Features contemporary Scandinavian finishes, solid-surface countertops, marine sanitation, and a fully enclosed shower stall.
The interior materials palette leans heavily into natural woods, matte metallic accents, and high-performance marine fabrics, maintaining a minimalist yet ultra-luxurious ambiance throughout.
Propulsion Engineering and Performance Metrics
Performance is a foundational pillar of the Nimbus brand, and the Sport Weekender 42 Open is engineered to deliver breathtaking on-water dynamics. The hull design and power options work in tandem to ensure that the vessel handles rough offshore water with the same poise it displays cruising glassy coastal bays.
The Twin-Stepped Hull Design
At the core of the SW42 Open’s performance envelope is its twin-stepped hull. By introducing strategic air induction steps along the wetted surface of the hull, hydrodynamic drag is significantly reduced.
This design delivers several distinct operational advantages:
- Higher Top-End Speeds: Breaking the suction between the hull and the water allows the vessel to achieve higher maximum velocities with equivalent horsepower.
- Accelerated Time-to-Plane: The boat lifts onto plane almost instantaneously, minimizing the awkward transition phase and reducing bow rise, which preserves forward visibility for the helmsman.
- Enhanced Fuel Efficiency: Reduced drag translates directly to lower fuel burn per nautical mile at cruising speeds, extending the vessel’s operational range.
- Superior Rough-Water Handling: The air cushion created by the steps cushions re-entry when powering through choppy seas, resulting in a drier, softer ride for all passengers.
Outboard Power Options: Mercury Verado V8 and V10
Embracing the global shift toward high-horsepower outboard propulsion in the luxury daycruiser segment, Nimbus has partnered exclusively with Mercury Marine to power the Sport Weekender 42 Open. Buyers are offered two distinct tiers of high-performance propulsion:
