William B

Whether seeking to entertain clients, have a celebratory staff party, or give your wedding or birthday party guests an event to remember, the William B offers a high standard of quality and versatility.

Inside, the fully upholstered teak panelled entrance hall with its polished brass wall lights and handrails makes an impressive introduction. A spacious bar and a formidable galley provide an exciting array of exceptional food and drink. 

New for 2018, our long and wide open roof deck has been gently transformed into a green and pleasant roof garden with quality artificial grass and wooden garden-style furniture. It is a lovely place to be on a summer’s day or evening, and also retains it’s cosiness on a clear Winter’s night.

The deliciously welcoming teak panelled entrance hall leads on to a modern and contemporary stateroom complete with high-quality carpets, sleek and polished wooden flooring and fresh, clean lines.The space is wholly flexible for large seated dining groups, or more informal drinks and canape parties. 

The subdued lighting and authentic nautical touches add to the luxurious feel of the surroundings.
