The Full GRP Cabin is the hallmark of the range, and is developed for the serious leisure and commerical operator. The cabin has allowed the Stormforce 11 to venture further offshore in complete safety and protection. The cabin is fitted with toughened marine grade glass, and features wide side decks for access to the bow deck.

All Cabin versions feature twin berths and a toilet in the bow. There is the usual space on the dash for placement of electronics, and some users also opt to place some of their equipment on the cabin roof. The layout of the seating is very much up to the requirements of the owner; some are built with Scotia Comfort seats, some are built with KAB suspension seats and wrap around benches aft.

There are several slight different versions of the Cabin version:

• Full cabin with cockpit aft (between cabin and engine bay). This can also allow us to place additional seating on the engine lid if required.
• Full cabin with flush aft deck. This is fast becoming a popular configuration. The flush aft deck prevents swamping of the cockpit in rough seas, and also reduces means the vessel is totally self draining. The aft deck is large enough to enjoy a family picnic, and shelter is provided by the cabin
• Shortened Cabin. This is a good choice for commerical users who require extra deck space aft. Normally, this version is shortened to still allow spacious placement of four KAB suspension seats in the cabin
