After party · The Snug Bar, Fry Place

Til late. You have earned it.

The two rules that matter

🔺Yellow on your LEFTEvery yellow buoy, the whole way
🔴Red on your RIGHTRed markers mark the navigation route. Keep every one on your right

And one more

After Buoy C, you and your swimmer stay within 20 metres of every yellow buoy. Buoys are 500m apart and lettered A to T.

A tall yellow triangular buoy lettered R
This is what you are looking for. Tall, yellow, triangular, lettered.

Your line, buoy by buoy

The start · Judy's Harbour to Buoy C

Take the direct line. A and B sit off to the side and are not on your route.

2.5km from the harbour to Buoy C. Two small yellow buoys sit at roughly 600m and 1.3km to guide you, and the Command Vessel is moored near C. Lead your swimmer straight at it.

Down Lough Ree · C to T

Leaving the lake · S to T

Gate 1. Lead your swimmer down the centre, between the red and the white marker. The yellow line is your path.

The motorway bridge gates

Gate 2. Relay boats hold here to let swimmers through.

At every narrow gate, you go first

Move ahead of your swimmer and lead them through. Boats on the course will hold. If one does not, raise your hands and direct it to move or hold position.

Swimmers have absolute priority. You are in charge of keeping yours out of danger.

The white railway bridge

Emergency · VHF Channel 8
"HELP
HELP
HELP"
then Kayak [your number]
at Buoy [nearest letter]
The nearest safety boat comes to you. Safety boats cover the full course.
📞 Swim Control · David Warby · 086 387 4258

For anything that is not an emergency, call "Swim Control" on Channel 8. Phone is the backup if VHF fails.

Your callsign

Kayak + your swimmer's number

The same number is on your radio and on both sides of your kayak. If your swimmer is number 21, you are Kayak 21, every time you speak.

If your swimmer is in trouble

1
They signal

Roll onto their back, hold the tow float, raise a hand.

2
You approach and assess

Get alongside. Talk to them. Ask simple questions.

3
You call it in

Channel 8, your callsign, nearest buoy letter.

4
They are extracted

RNLI, rescue boat or on-site divers. Ambulances are stationed along the course. A doctor is on the Command Control Boat.

Watch for hypothermia

Exhaustion or feeling very tired

Confusion

Memory loss

Slurred speech

Asking simple questions every so often is the easiest way to check. Watch for exhaustion too.

If a swimmer retires

Tell the Swim Coordinator. A safety team extracts them from the water. You paddle on to the finish.

Everyone you might need

Poor visibility

Prioritise situational awareness. If you are unsure of your position, stop and consult Swim Control. They will assess your situation.

Given to you at registration

✓ Two sticky numbers, front left and right of your kayak

✓ Your t-shirt, in the size you gave at sign-up

✓ Some goodies

✓ A dry bag for your swimmer's phone

✓ A VHF radio, already set to Channel 8

If you signed up after 25 July we may not have your exact t-shirt size. We tried.

Bring it yourself · tap to tick

Ticks are saved on this device for the session. Print the deck card if you want a version that does not need a battery.

Dressing for the day

Hot and sunny: dress light and sunscreen every exposed bit. You will be out for hours with water reflecting up at you.

Cold, or if the water temperature drops: a cag and an extra layer is worth it.

Helmets are not mandatory, but wear a cap or a hat.

On the bus

Space is limited. Wear your gear, and leave the buoyancy aid, helmet and spraydeck in the van with everything else. It all travels to the start for you.

Agree these three things before you launch

1
Which side you paddle on

Their preference, not yours.

2
How often you stop for food and drink

Set the interval now.

3
The signal for a feed stop

Something you can both see in chop.

Your two jobs, in order

1. Keep them on course

Even slightly choppy water makes it very hard for a swimmer to see where they are going. This is the job.

2. Feed and hydrate them on their schedule

The one you agreed on the bank.

On the water

Your swimmer stays parallel to your kayak the whole way, including through the narrow sections.

They swim at an all-day pace. It will feel slow to you. Keep checking your own positioning.

Watch the water for changing conditions or incoming weather, and keep your swimmer posted.

Constant communication is the difference between a good day and a miserable one for them.

Rules your swimmer must follow

Bright orange swim hat, worn and visible the whole way

Tow float, mandatory

No fins, paddles, boards or pull buoys

No going on land at any point during the swim

And for everyone

Respect the environment and the people who live along this water. No litter, anywhere.

Respect and help your fellow kayakers and swimmers.

Listen to the marshals and safety teams. They are there for everyone.

Spectators
