FAST and SAFE Performance Sailing

The big sister to the extremely successful 40, the new Nautitech 46 Open is the latest addition to  the ‘Open’ range of multihulls.

Featuring vast living spaces, maximum comfort for long passages, and ultra-modern finishes throughout, the Nautitech 46 Open is a cruiser’s dream.

This model features many welcome features found on the 40, including twin helm positions, a transom passage giving easy access from one hull to the other, rigid bimini providing complete shelter to the cockpit, and gracefully inclined forward saloon windows, creating a sleek and elegant appearance.

Going with the trend in cruising multihulls today, the layout of the Nautitech 46 Open is all about entertaining. From the sun lounge on the bow trampolines to the bright, open saloon to the big cockpit astern, traffic flow for a multitude will be easy.

In the gallery above, you will see that the 3 cabin version boasts a stunning owner’s hull, with private study/dressing space, and separate heads and shower. In the 4 cabin version, each cabin has its own bathroom and shower.

The Nautitech 46 Open is for the enthusiastic audience among sociable sailors who want the comfort and style of a nice seaside apartment along with the ability to handle rough conditions when they occur. It would be a nice platform for cruising the East Coast in summer and going south to the islands when winter comes.
