Waterways Ireland advises masters of vessels that water levels on the Shannon Navigation have dipped below Ordinary Summer Levels, due to low seasonal rainfall. Consequently, there is an increased risk of groundings and this cautionary warning is likely to remain for some time.
Navigational guidance for masters of vessels:
1. Remain within marked navigation channels at all times.
2. Give navigation markers a wide berth and ensure passage on the correct side.
3. Plan passages carefully, taking vessel draft into account.
4. Adhere to local speed limits and exercise caution in restricted or shallow channels.
Guidance if vessel grounded. If your vessel becomes grounded in shallow water, follow the steps below to ensure safety:
1. Disengage the engine immediately to prevent damage. Check safety of all passengers.
2. Remain onboard and ensure all persons wear lifejackets. Do not enter the water.
3. Check the internal watertight integrity of the vessel for any signs of leaks or damage.
4. Attempt to manoeuvre off gently, using minimal engine power, do not apply excessive force. Consider emptying freshwater tanks.
5. If unable to refloat:
- Seek external assistance.
- Call 112 or 999 and request the Coast Guard.
- If you are on a hire vessel, also contact your Hire Boat provider directly.
- Do not enter the water
6. Post grounding check your hull, prop and steerage as a matter of priority.
Waterways Ireland advises all masters to plan passages carefully, particularly in areas affected by low water levels. More information on Shannon water levels can be found here: Water Levels
