Southampton, UK-based shipping fitting company Trimline assembled the prototype cabins, which were unveiled last week. Trimline assembled the cabin structure and then fitted out the interior – the bed and all the furniture are also constructed of composite to keep weight down.

“We are planning to officially launch at SMM Hamburg in September where the cabin will be on display. There is still some work to do on certification but all the tests done to date are looking very promising and then hopefully we can go into production,” said a spokesman for the company.
