Circumstances of loss

In June 2016 during a side scan sonar survey being conducted for the local harbour authority in the eastern area of Scapa Flow a small object was detected on the seabed. Subsequent investigation of the site using a drop video system showed what appeared to be a small Yarrow-type steam boiler that was commonly used in steam pinnaces, with what appeared to be a funnel lying alongside. No other wreckage was seen.The funnel, lying on the seabed beside the boiler was of a heavy brass construction and its design with small vent holes at base was typical of Royal Navy steam pinnace design. The funnel appeared to have been crushed. There were a number of small items of debris lying on or partially buried in the seabed around the boiler. These mainly comprised items that would have been found in the boiler or engine room and included lamps, pressure gauges (one of which was attached to a brass plate), brass pipework, port holes and small fragments of wood with copper nails protruding. show a brass object that may have been from a boat hook.
