Accommodations

Wheelhouse

Entering through the wheelhouse, you are initially greeted by 360 degree views and an area that it flooded with light. facing forward is the commanding helm position which also acts as the nerve centre for the boats electrical systems. Aft of the helm are two wheelhouse bench seats and side tables. these tables can be moved to turn this area into a fantastic dining space, allowing you to take in the surroundings while you eat. 

Primary Cabin

Immediately aft of the wheelhouse is the primary cabin. Going down a small set of steps take you to a large island bed which has ample storage on either side. large mirrors can be found on either side of the entry way, and behind these are 2 large hanging lockers. 

Bathroom

Immediately forward of the wheelhouse is the main accommodation space. As you move forward, you will firstly find the large bathroom to starboard. As you enter, you find a rare luxury on a boat.... a bath. The bathroom is completed with a shower above the bath and  washbasin with large mirror behind. This is one of the spaces where the amazing fit-out rally comes into its own. The warm woods are offset against darker tiling to create a highly refined space to start or end your day.

Galley

As we continue forward we come to the full beam galley. this space is filled with storage, for longer stays aboard, along with everything you need to cook full meals aboard. The galley has a 4-burner gas hob with oven directly below. The U-shaped galley is completed with an integrated sink and drainage board, dishwasher, fridge, freezer and microwave. The final integrated feature is vital for longer trips... a ironing board. This can be found here and is accessed by opening one of the top drawers. 

Saloon

As you proceed to the most forward compartment you will find the final space, the saloon. This full beam area offers a multifunctional space where you can choose to relax on the ample sofas, work at the integrated desk or entertain using the hatchway into the galley, allowing the easy transfer of things between the two spaces. A TV can also be found here, and it is stored in its own bespoke cabinet. This space can also be used an an occasional berth, with a sofa converting into a double bed. 

Engine Room

Directly below the wheelhouse is the heartbeat of the boat. by going down a small ladder you will find a space that is spacious for this size of boat. In here you will find the washing machine along with the engine, generator, battery bank, invertor calorifier and more.
