Tying to Pilings on the Rideau
Tying to pilings is one of those skills that looks obvious until you do it wrong once. On the Rideau Canal, pilings are common at lock walls and some overnight tie-ups, and they behave very differently than floating docks.
The key difference is simple but critical: pilings do not move — your boat does.
Why pilings are different
Unlike floating docks, pilings are fixed vertically. Water levels on the Rideau change constantly due to:
- Lock operations
- Wind pushing water through narrow sections
- Seasonal and weather-related fluctuations
- Boat loading and unloading
If your lines are tied incorrectly, the boat can end up hanging, surging, or grinding against the wall. This usually happens quietly and quickly, often when no one is watching.
The single most important rule
Lines tied to pilings must be able to slide.
You are not tying the boat to the piling. You are securing the boat alongside the piling while allowing vertical movement.
That means:
- No fixed knots directly around the piling
- No locking the line in place
- No lines that go tight as water levels change
The correct basic setup
The standard and safest method is:
- Run the line from the boat around the piling
- Bring it back to the boat
- Secure it to a cleat onboard
This creates a loop that can slide up and down the piling as water levels change, while still holding the boat close and controlled.
The line should be long enough to allow movement but short enough to prevent excessive drifting.
Bow and stern lines
At a minimum, you will normally use:
- A bow line looped around a forward piling
- A stern line looped around a rear piling
These lines control fore-and-aft movement while allowing vertical travel. They should lead cleanly, without sharp angles or rubbing points.
Spring lines are usually unnecessary in locks and most Rideau tie-ups, as the goal is controlled vertical movement rather than resisting forward motion.
Line length matters
Lines used for pilings should generally be longer than typical marina dock lines. Short lines are more likely to:
- Go tight during lock operations
- Bind on rough concrete or metal
- Pull the boat awkwardly toward the wall
Extra length gives you flexibility and margin for error. Excess line can always be managed on deck.
Watch for chafe
Many Rideau pilings and lock walls are concrete or steel. Some have rough edges, seams, or hardware that can abrade lines over time.
Pay attention to:
- Where the line contacts the piling
- Any sawing motion as the boat moves
- Noise or vibration indicating friction
If needed, adjust the lead angle or reposition the loop to reduce wear.
Leaving the boat unattended
When tied to pilings overnight or while away from the boat:
- Double-check that lines can slide freely
- Ensure there is enough slack for expected level changes
- Confirm fenders are properly placed and will stay in position
A properly rigged boat should look slightly loose, not pulled tight. That looseness is intentional.
Common mistakes to avoid
- Tying a hard knot directly around the piling
- Using lines that are too short
- Forgetting about lock water level changes
- Assuming pilings behave like floating docks
Most piling-related issues come from treating them like something they are not.
Why this matters
Tying to pilings correctly turns lock walls and fixed tie-ups into calm, predictable stops. It reduces stress, prevents damage, and lets you step away from the boat with confidence.
Once you understand how pilings work, they stop feeling intimidating. They become just another normal part of cruising the Rideau.
