Technohull Alpha 45 — 13.80 m high‑performance RIB

A 13.80 m RIB with a 4.30 m beam, roughly 6,500 kg hull mass (engines excluded) and up to 1,400 L of fuel changes marina planning: berth lengths, pile loads, crane capacity and fuel logistics must be reassessed before a Technohull Alpha 45 arrives. Add the shipyard’s declared potential of 4 x 500 hp outboards and a claimed top speed in excess of 85 knots, and the operational picture moves from "typical dayboat" to "dedicated performance asset" for owners and charter managers.

Hull, propulsion and offshore behavior

The Alpha 45 uses a Dynastream Deep‑V hull with ventilated steps and redaning to reduce wetted surface at speed. This architecture targets fast offshore runs: the deep‑V and sharper, more vertical bow help cut through chop and reduce slamming at high speed, while the stepped sections let the boat breathe over the water to shed drag.

That said, stepped hulls are not free lunch: fuel burn rises exponentially with speed, and ventilated steps require fine tuning to avoid unpredictable ventilation at rough angles. For operators thinking of chartering such a boat, engine selection (number, weight and configuration of outboards) becomes a logistics and maintenance item as much as a performance one.

Deck layout, circulation and marina footprint

The Alpha 45’s relatively generous beam for a RIB creates a true walkaround deck. A U‑shaped fore sunpad and centre‑console seating give a social layout ideal for day runs in warm climates: think quick anchoring, on‑deck sunbathing and rapid boarding from a swim platform.

But a 4.30 m width also enlarges the port footprint. In busy marinas—especially older Mediterranean marinas built for narrow cruisers—owners and brokers must account for higher berthing fees and possibly different berth categories. Lifts and travelifts must be rated for the combined weight of hull plus outboards; trailering is rarely practical for such displacement and engine mass.

Practical dockside checklist

• Confirm berth width and length allowances at preferred marinas.
• Verify travelift and crane capacities before haulout.
• Plan fuel logistics: 1,400 L tank plus heavy consumption at high speed.
• Arrange for certified helmsmen for charter operations at performance speeds.

Helm ergonomics and aerodynamic protection

The helm centers the pilot in a three‑across row of seats, improving sightlines and balance control when punching through waves. A sloped windshield and hardtop with adjustable side deflectors aim to tame airflow; at sustained 40–60 knot cruising speeds, that aerodynamic work is not cosmetic—it’s about passenger endurance. I've seen a few performance helms where bad airflow makes a 20‑minute dash feel like an afternoon of sandblasting—this design attempts to avoid that.

Onboard configurations and use cases

At the stern, Technohull provides multiple layouts: a large sunpad for dayboat use, a compact sea‑facing seating plan, or an L‑shaped lounge to ease platform access. Below decks, an electrically‑operated console door leads to a double berth and a separate head with shower, making short overnighting feasible without claiming the boat as a proper cruiser.

Certification, target market and operational realities

With CE Category B certification and space for up to 16 persons, the Alpha 45 straddles two worlds: it is designed to handle offshore conditions (up to force 8 in the CE envelope) while remaining attractive as a high‑end dayboat or sporty weekender. That means the ideal buyer is a seasoned owner or operator who values performance and understands the narrower weather window and higher running costs inherent to such a platform.

Pros and cons at a glance

• Pros: blistering performance potential, roomy deck for a RIB, overnight capability.
• Cons: steep fuel and maintenance costs, larger marina footprint, requires experienced crew at speed.

In short, the Technohull Alpha 45 is not a one‑size‑fits‑all solution: it’s a high‑performance RIB that brings specific demands on transport, berthing and crew training. For charter operators and private owners thinking of adding such a boat to a fleet, the decision hinges on balancing thrilling speed and sea‑keeping against higher operating costs and marina logistics. Bottom line: if you want pace and a usable cabin in one package, be ready to manage the berth, the fuel bills and the captain who knows how to handle it.

Summary: The Alpha 45 pairs a stepped deep‑V hull and ventilated sections with up to 4×500 hp outboards to chase very high speeds, but the trade‑offs are clear—larger beam and port footprint, heavy lift requirements, sharp fuel consumption and a narrower weather window. For yacht owners, charter managers and brokers, considerations around berth availability, crane capacity, certified captains and maintenance budgets will determine whether this RIB is a winner for day charter, weekender use or sale. Whether you’re after a superyacht chase boat, a sporty dayboat for marinas in the gulf or a fast platform for fishing, sailing activities or beach hops, the Alpha 45 forces planners to weigh speed against practicalities in sea, ocean and marina operations.
