Designed around speed, offshore capability, and practical comfort, the model introduces a revised aerodynamic profile and a stepped Dynastream Deep-V hull capable of exceeding 85 knots with quad 500hp outboards.
The Alpha 45 enters a competitive segment where dayboats are expected to deliver both pace and usability. Technohull’s latest model focuses squarely on that brief, with a beam-to-length ratio engineered to preserve deck space while maintaining offshore handling credentials under CE Category B classification.
Engineering for an 85 Knot Capability
At the heart of the Alpha 45 is Technohull’s Dynastream Deep-V hull with ventilated steps. The stepped geometry is tuned for high-speed efficiency and stability, while a pronounced wave-piercing bow is designed to improve ride comfort in heavier sea states. The yard states that with four 500hp outboards installed, the boat reaches a cruising speed of over 40 knots and a top speed beyond 85 knots. Alternative outboard and inboard configurations are available for owners prioritizing different operating profiles, including extended cruising range.
The superstructure also introduces a revised windscreen and hardtop design. A more aggressively raked profile and sculpted surfaces are intended to reduce aerodynamic drag at speed. Integrated side deflectors can be opened to channel airflow away from the helm seating area, improving comfort for those seated behind the console during fast passages. It is a detail that signals Technohull’s focus on high-speed ergonomics rather than headline figures alone.
The Alpha 45 is a serious new addition to our luxury performance line-up, drawing on the best of Technohull while adding a few new design enhancements of its own."
- Gerasimos Petratos, CEO of Technohull
Light ship weight is quoted at approximately 6,500 kilograms excluding engines, supported by a 4.3-meter beam and 1,400-liter fuel capacity. Water capacity stands at 150 liters.
A Helm Designed for Command
The Alpha 45’s helm configuration is a defining feature. The console carries two rows of triple seats, with the helmsman positioned centrally. This layout not only ensures balanced visibility but also places primary controls directly in front of the driver. In performance craft operating at these speeds, sightlines and reach matter, and the central helm reinforces the tender's driver-focused character.
The forward section of the console incorporates a bench seat facing ahead, positioned just abaft the bow sunpad. This creates a social area that remains engaged with the direction of travel rather than turning its back to the action.
Modular Aft Layout Options
Despite its performance brief, the Alpha 45 is designed as a full walkaround. The beam supports safe circulation from bow to stern, an important consideration on a boat rated for up to 16 passengers.
At the bow, a generous U-shaped sunpad dominates the foredeck. Aft, owners can specify either a compact or extended sunpad with forward-facing seating into the cockpit. An alternative layout replaces the sunpad with an L-shaped settee, creating easier portside access to the swim platform without stepping across cushions. On inboard versions, a large sunpad is positioned above the engine compartment.
These configuration options underline the model’s dual role. It can function as a pure performance platform or as a sociable dayboat with defined lounging zones.
Cabin and Overnight Capability
Access to the lower deck is via a side-console gullwing door that opens at the push of a button. This arrangement keeps the forward console dedicated to navigation and electronics while providing direct entry to the accommodation space.
Below deck, the Alpha 45 offers a double berth for two and a separate full-beam head with shower. Standing headroom is available in the bathroom, a notable detail in a 13.8-meter sport boat where lower deck comfort is often secondary. The layout supports weekend use without compromising the primary deck plan.
Comparing the Alpha 40, 45, and 50
According to YachtBuyer MarketWatch, the largest yacht database in the world, the new Alpha 45 sits directly between the Technohull Alpha 40 and Technohull Alpha 50 in both size and intent. However, it pushes the performance brief further.
At 12.1 meters, the Alpha 40 is the most compact of the trio, with seating for up to 11 passengers and an 800-liter fuel capacity. Its 3.5-meter beam and GRP planing hull position it as a practical, agile option suited to shorter coastal runs and yacht tender duties.
At the other end, the 14.95-meter Alpha 50 offers greater length, a broader 4.72-meter beam, and a larger 1,800-liter fuel capacity. It retains overnight accommodation for two guests and presents a more substantial platform for extended day cruising.
The 13.8-meter Alpha 45 bridges this gap with a wider 4.3-meter beam than the 40, more aggressive top-end performance, and a higher maximum power configuration. Compared to the 50, it is slightly shorter but more overtly performance-led, particularly in quad 500hp form. In practical terms, the 45 positions itself as the most speed-focused model in the current Alpha lineup, while still delivering walkaround deck space and genuine weekend capability.
