Carbon and wood, two seemingly antithetical elements that come together in a single hull, the WB40′ Classic by Wooden Boats. A shipyard created by studio Arnaboldi, a naval engineering office that boasts collaborations with brands such as Benetti, Sanlorenzo, Pershing, Mangusta and Baglietto, to name but a few.

WB40′, the 40-knot carbon wooden boat

Wooden Boats was created in 2012 and has been involved in many projects like full custom tenders for large yachts with 18 boats delivered in 8 years. Marco Arnaboldi, naval engineer and founder of the project, has created this boat, the WB40′, combining two very different materials: the classic wood, synonymous with elegance, and advanced carbon composites.

The first WB40′ Classic is a 12.95m day cruiser for a European shipowner. The hull and deck are made in sandwich with multidirectional layers of mahogany and pre-preg carbon fiber using the vacuum epoxy resin technique.

Totally designed, engineered and produced in-house, it has a deep V-shaped hull designed specifically for waterjet propulsion. The WB40′ Classic combines optimum performance and excellent seaworthiness, without vibration in all sea conditions.

This Arnaboldi’s project is wood and carbon fiber made, but Wooden Boats is also specialized in making hulls using only advanced composites.

The deck of WB 40′

The deck is the highlight of the boat and can accommodate up to 14 guests on board. The WB40′ Classic has a sun deck above the deckhouse, a central cockpit with a height-adjustable table that can be converted into an additional sun deck. A third sundeck is located above the engine room. The wheelhouse is raised above the deck to ensure improved visibility when navigating and manoeuvring.

Aft of the wheelhouse is the kitchen cabinet with sink, worktop, two burners and fridge. The whole area can be protected by a bimini top (there is also a version with hard-top and hull entirely made of carbon fiber with foldable walls to increase the surface of the bathroom platform).

Below Deck

Though it’s a daycruiser even below deck there’s plenty of space. A double bed, bathroom with toilet, washbasin and shower.


Motorized with a pair of 420 horsepower Yanmar MJP hydro-jet coupled and equipped with the latest generation joystick, the WB40′ Classic reaches a top speed of 40 knots and a cruising speed of about 36 knots.
