AT42

Power Meets Elegance

Elegance and Sportiness in One Exceptional Vessel
The AT42 is more than a day boat—it’s a bold statement of performance, style, and versatility. Designed with sleek, elegant lines and engineered for serious offshore capability, it represents the pinnacle of ALPHA TANGO®’s open-deck RIBs.

Built From the Hull Up to Perform

The AT42’s hull has been reimagined and scaled to deliver even more—more performance, more space, and more confidence at sea.
Its lightweight, double-stepped deep-V hull ensures unmatched stability, responsiveness, and cruising comfort, even in heavy offshore conditions. This is a boat built to go anywhere, anytime – with purpose and poise.

Spacious Cabin

Behind the streamlined console, a signature Goldwing door reveals a full-size cabin with premium features:

A queen-size bed
Full-beam enclosed stand-up shower and WC
Generous storage including a vertical wardrobe and under-bed compartments

Whether it’s a weekend escape or a longer adventure, the AT42 offers all the comforts you need.

Expansive and Customizable Deck Layout

Thanks to its generous beam, the AT42 boasts one of the most spacious decks in its class.

Highlights include:

Two triple-row seating configurations under the hard top
Integrated wet bar with sink and optional twin electric fridges/freezers
Rear-facing sofa seating up to nine under permanent shade
Optional aft lounge with two dining tables (seats 8), easily convertible into a 2.30m x 1.50m sunbed or full-beam lounger with forward-facing sofa (seats 5)
Large swim platform for easy water access and docking

Every layout can be tailored to your preferences – making this the ultimate all-day cruiser.

Deck Versatility

At the bow, you’ll find:

A forward-facing two-person sofa
A large sunbed that fits four people and converts into a canvas-enclosed sleeping space for two

Perfect for entertaining, relaxing, or overnighting in comfort.

Optional Aft Cabin for Extra Accommodation

The aft lounge cleverly lifts to reveal a second double cabin—ideal for families or traveling with friends. Discreet, stylish, and practical, this feature extends your onboard living space without compromising design.
