Rowing will be suspended and no boating will be allowed when the visibility is reduced to 400m or less. It should be noted that this distance extends well beyond the Sounding Arch which has often been mistakenly used as a visible landmark to determine whether it is safe to row.

At times of fog it must be realised that conditions vary with time and along the reach.

When there is fog the Captain, Safety Advisor or nominated coaches will decide if it is safe to row and may limit and organise boats to ensure safe rowing. If conditions worsen then boats should carefully return to the clubhouse.
