Once in a while a real innovative boat is introduced on the international boating market. All innovative concept require, due to their own nature, a reasonable testing time; in our opinion every boater should consider unusual ideas because they can, sometimes, change and improve the way we all live at sea. The Virgola 33 is "the innovative boat of the year" without any doubt. This yard, managed by Ezio and Franco Marchi, has, on the other hand, introduced, recently, several innovative boats, preserving, however, that precious craftsmanship capability of which they are reasonably proud of . All we are trying to explain is that innovative concepts require new ideas and strong building capability, which are only ensured by a long tradition.

The Virgola 33 is a futuristic boat: a modern multihull which is capable of superior performances together with excellent docking capabilities usually found on single-hull boats and which will perfectly fit the standard marinas berths. The two side hulls, in fact, shift, with a simple operation which require just 5 to 10 minutes, till they lay completely alongside the main hull, thus reducing the max. beam from 8,35 to 3,50 meters. Sea trial were performed with moderate swell and a boring 15 knots E/SE wind.

The boat was, anyway, very interesting both under sail and under power achieving a remarkable comfort and low fuel consumption. The recovery operation of the two side hulls, has been performed in the marina harbor, displaying all its practicability: the operation took just 5 minutes. The Virgola 33 feature excellent accommodations as well. The steering wheel can be placed on the center of the cockpit or at its side as well thus improving the working space while a large stern cabin can be found below deck. Forward of it there is a practical convertible dinette followed by the galley and the V berth bow cabin with lockers.

The bathroom is spacious and ensure a convenient access from the bow cabin and the galley area as well. In conclusion, all the boat's innovative features compared with its overall dimensions, make of the Virgola 33 a perfect "boat of the year".
