Colour Legend:


A variety of sources have been used to build the list and place the locations of the wrecks or the location of the grounding. John Findlay's research (Swona Revisited) formed the basis for the comprehensive list of incidents and sense checking the locations, using press articles, official records and oral history. 

Marked up maps have formed the basis for the locations but have provided differfering accounts which has complicated the process.
