Technohull Alpha 45: 2,000 HP RIB with 85+ Knot Top Speed & Overnight Cabin
Technohull, the Athens-based shipyard, launched the Alpha 45 in March 2026. This 13.8-meter RIB (Rigid Inflatable Boat) is designed to punch through 85 knots with a quad-outboard configuration totaling 2,000 hp. It is not just a speedboat; it's a high-performance platform with an overnight cabin and a flexible deck layout.
1. Hull Design: Dynastream Deep-V with Steps
The secret behind the Alpha 45's speed lies in its Dynastream Deep-V hull with ventilated steps. This is not a standard V-bottom.
- Stepped Hull: This stepped design reduces the hull surface area in contact with the water at high speed, drastically cutting drag.
- Wave-Piercing Bow: The sharp, vertical bow is designed to slice through waves rather than slap against them, improving comfort in open water.
- Certification: CE Category B, designed for offshore voyages with winds up to force 8 and waves up to 4 meters.
2. Powertrain & Performance
The Alpha 45 is offered in various configurations, both inboard and outboard. However, the most extreme variant uses four outboard engines.
- Max Power Configuration: 4 x 500 hp outboards (2,000 hp total).
- Top Speed: >85 knots (~157 km/h) in max configuration.
- Cruising Speed: 40+ knots, balancing speed and fuel efficiency.
- Fuel Capacity: 1,400 liters for extended journeys.
3. Dimensions & Weight
| Specification | Value |
|---|---|
| Length (LOA) | 13.8 m (14.05 m for inboard version) |
| Beam | 4.3 m |
| Dry Weight (light ship, no engines) | ~6,500 kg |
| Fuel Capacity | 1,400 L |
| Fresh Water Capacity | 150 L |
| Passenger Capacity | 16 (CE Category B) |
4. Aerodynamics & Cockpit
Technohull redesigned the windscreen and hardtop for the Alpha 45. The rake is more extreme, and there are opening side deflectors to channel wind away from the helm seats.
- Helm Position: The driver sits centrally within two rows of triple seats, offering optimal visibility in all directions.
- Walkaround Deck: The 4.3m beam allows unobstructed circulation from stern to bow.
- Aft Layout Options: Choose between a large sunpad, a compact sunpad with sea-facing seats, or an L-shaped settee for easy platform access.
5. Cabin & Overnight Capability
Despite its muscular speed profile, the Alpha 45 retains space for overnight stays. Cabin access is via a gull-wing door next to the console that opens automatically.
- Double Berth: Sleeping accommodations for two below deck.
- Separate Head: Enclosed bathroom with shower and standing headroom.
- Interior Access: The gull-wing door keeps the main console area free for instrumentation.
TECH INSIGHT: Ventilated Steps
A stepped hull forces air under the boat at high speed. This layer of air reduces friction (drag) dramatically, allowing the vessel to achieve higher speeds with the same power. This technology is common in offshore racing and is key to the Alpha 45's 85-knot capability.
Conclusion: The Greek Speed Machine
The Technohull Alpha 45 is a statement that RIBs are no longer just tenders. With 85+ knot speeds, advanced hull design, and a cabin that rivals some smaller cruisers, it bridges the gap between pure performance and practical day-boating. It's a serious contender for anyone looking for the fastest rigid inflatable on the market.
