The lifeboat has a moulded fibreglass rigid hull, topped with a marine quality plywood deck.

A tubular aluminium roll-bar carries communication aerials for GPS satellite navigation and VHF radio, along with an inflatable airbag for self-righting.

The twin Evinrude 70-hp engines were modified at the RNLI's Inshore Lifeboat Centre at Cowes, to prevent water ingress in case of capsize, and allow restart.

This ballast tank is filled using a water scoop located between the engines, and keeps the bow of the lifeboat weighed down, allowing higher speeds.
