The 46 Mahon holds class A approval and has an hull of 14 metres long with beam of 4.21 metres. The boat has two very roomy double cabins, two generously fitted bathrooms with shower enclosure, and plenty of space for wardrobes and drawers. On the upper deck, behind the steering position, is a large dinette area with bench seats and dining table. The corner galley, on the cockpit side of the saloon, features a full set of appliances and a large working area.

A folding plate glass door leads to the cockpit, which has a large sundeck that converts into a bench seat with central table for open-air lunches. The particulary design of the stern, gives easy access to the bathing platform, which can be hydraulic on request to facilitate entering and exiting the sea.

The distinctive details, finishes and accessories of the Austin Parker style designed by Fulvio De Simoni are still very much in evidence, especially in the unmistakable dark blue livery, the wide, protected walk-arounds from stern to bows, the large sundeck, the use of mahogany and teak.
