Poor posture, inadequate seating and a host of other factors can lead to life- changing injuries on RIBs as passenger safety is pulled sharply into focus by recent events in the small craft sector. If the sector ’s reputation is to survive accidents like Seadogz, owners and operators need to start owning best practice, controlling the risks and demonstrating that their trips are safe, says MAIB (Marine Accident Investigation Branch) as it cracks down on the small craft sector saying ‘Small craft sector must educate customers of dangers to avoid passenger injury’.
When you are trying to promote the fun element of an activity, telling your customers that it can be hazardous might appear counterproductive. This could explain the reluctance of the ‘small-craft passenger/ experience ride’ industry to acknowledge and take action on the findings from recent accident investigations.

Marine surveyors and boat owners are regularly heard to say there is a minimum 4.0mm of hull thickness required at time of survey of a steel narrowboat. Some brokers even publish videos of such information, with some surveyors enforcing it (Whilton Marina, 2012 and 2016). Boaters are subject to it and repair often follows. In a recent article, Geoff Waddington (2021) explains there is confusion in the industry about wastage limits, and consequently acceptable residual hull plate thicknesses, and opinions among surveyors ‘vary wildly’, with some quoting 3mm acceptable minimum plate thickness, others using percentage loss. This short paper explores what a standardised acceptable limit for diminution, and therefore residual steel plate thickness for narrowboats, could be. It describes a variety of methods of calculating the design plate thicknesses (scantlings) and the minimum acceptable residual plate thickness. In doing so, this paper aims to serve as a guide for inland waterways marine surveyors, boat owners, repairers, and insurers alike.
