Anyone heading on to the water should exercise caution and keep a careful watch for submerged or floating debris washed into waterways.

Commissioner Stacey Tannos said Marine Rescue NSW encouraged boaters to check on the condition of their vessels and moorings now the weather had improved.

“Some simple checks could reveal storm-related damage and other issues that need immediate attention to help prevent the risk of breakdowns or worse next time you head out,” he said.

“Moorings also need to be checked and boats that have come loose will need to be re-secured.

“People should take extra care on the water in the aftermath of the week’s conditions. Logs and other large pieces of debris are often submerged and can cause serious damage to bows and propellers if struck at speed.

“Keep a close watch on the waters ahead and look out for loose or even submerged vessels in popular mooring areas,” he said.

Boaters should check:

The dependability of their moorings. Dozens of vessels were torn from moorings during the storms. The strain on moorings that held fast was immense and unless they have been regularly serviced, may be in danger of failing. Only a physical check will indicate whether attention is needed.

Water in the bilges. Rainwater may have been forced under covers to collect in the bilges. Automatic bilge pumps should have activated but only a check will confirm whether bilges are dry or becoming filled with water. Vessels without automatic pumps should definitely be checked.

Wet electrics. Driving rain is notorious for affecting electric connections. Maintenance is vital to ensure all electrical equipment is working.

Moisture and mould: Cabins should be opened and aired to prevent damage cause by wetness and mould.

Hidden damage on trailer boats: Trailer boats are also subject to the possibility of storm damage that may not be discovered until next time the owner wants to use their boat.
