Plan copied at reduced scale. An ozatrace copy of a plan showing the incident board on No. 1 [upper], No. 2 [main], No. 3 [lower], No. 4 [hold] and No. 5 [hull bottom] decks on the Rothesay class frigate Yarmouth (1959). This panel would be on the wall and would light up if an incident (such as fire, flooding or a injury) was reported in a specific location on board. This drawing was revised at Rosyth Dockyard on 19 April 1971 and 14 April 1975.
