comfortable ride, with less slamming load transferred to operators. HDPE does not corrode, or suffer from electrolysis, reducing maintenance costs and increasing operational availability. It was the PFG Group, of Hobart, Tasmania, who recognised and applied the advantages into RHIB construction. In partnership with One2Three Naval
Architects, Stuart Downham of PFG developed a range of RHIB designs and builds which have such significantly favourable characteristics in the water that the future of RHIB's and high performance small watercraft will shift towards HDPE as the preferred hull material.

Some RIB manufacturers, particularly those popular in Ireland and the West Coast of Scotland provide optional canopies which form fabric and perspex wheelhouses but can be easily removed in good weather. Increasingly, RIBs are becoming available with small cabins (usually with accommodation for two people and in some cases sea toilets or

In the 2010s, the traditional RHIB was reimagined using High-Density
Polyethylene (HDPE) as the hull material. HDPE, an engineered polymer, possesses a number of properties which make it a superior marine construction material for RHIB's. Of note, it absorbs vibration leading to a quieter, more

In 1978 the demand grew for more protection in the form of an integral cabin and outboard well to protect the crew in adverse conditions. Though basic to start with cabins soon became more sophisticated. Naiad were one of the early pioneers in designing RHIBs and models range from 2.5m to 23m.

The Naiad RHIB developed by Steve

RIBs can also generally cope better with rougher seas, although this may be partially due to an increased level of confidence in knowing that a RIB is hard to sink, and better absorption of heavy loads by the flexible tubes, which therefore make heavy seas less unpleasant.

Modern "all round" RIB hulls combine a deep v hull at the bow which flattens out to present a broad planing pad. This is a flat area on the rear of the hull designed to allow the boat to have a stable surface to plane on.
