Relocation means relocation of all personnel (competitors and officials) and equipment (including water safety and first aid) necessary to conduct the relevant competition(s). It does not necessarily mean back of beach items such as stands or signage.
The aim of relocating to an alternative venue is to ensure that the competition may be safely conducted within the timeframe set down.
If water conditions prevent water-based competition, and the beach itself is unaffected, then only water events may need to be relocated.
