Two super yachts owned by American billionaire Gabe Newell are expected in the port today (Wednesday).

First to arrive in the morning will be the super yacht tender Dapple going into the Pendennis wet-dock complex followed in the evening by the £80m Rocinante berthing at the Port Pendennis marina.

Dapple is a super yacht tender equipped with a state of the art decompression chamber, dive chamber and a Triton 330 submersible. Aft she has a large helideck that can handle the most extensive commercial helicopters.

Rocinante from the Lurssen stable of super yacht builders is a 78.8 metre long vessel built in 2008.

Newell, who is well known in the world of video game development is worth an estimated £3.2 billion.

He started his career with Microsoft where he helped create the Microsoft operating system.

Apparently he is an active philanthropist supporting the Seattle Children’s Hospital and other causes.
