AIDS TO NAVIGATION

[Daybeacons] [Lateral Buoys] [Buoyage Reversal] [Navigation Charts and Guides] [Other reading]
Aids to navigation are devices designed to help boaters identify the navigation channels and determine their position and course. They also mark the location of hazards and obstructions. They should be used in conjunction with other data (charts, landmarks, Notices to Mariners and other available marine publications) when boating. Historic canal navigation aids conform to the Canadian Aids to Navigation System.

Most of the navigation aids on the Rideau Canal and Trent-Severn Waterway consist of fixed daybeacons and anchored floating lateral buoys. There are some lights as well. Mariners should note that these aids are not under continuous observation so light failures and out of place buoys do occur. Parks Canada staff appreciate receiving reports of any lights out of operation or buoys off position.

DAYBEACONS

Port and Starboard Daybeacons, 0.6K
Port and Starboard Daybeacons

The Starboard Daybeacon is triangular, with a red triangular centre on a white background, and a red reflective border. It is used at lock stations, bridge piers and as a channel marker on shorelines to indicate the starboard (right) side of the channel when proceeding upstream.

The Port Daybeacon is square, with a black square centre on a white background, and a green reflective boarder. It is also used at lock stations, bridge piers and as a channel marker on shorelines to indicate the port (left) side of the channel when proceeding upstream.

Bifurcation or Junction Daybeacons mark a point where a channel divides and may be passed on either side. When proceeding upstream, the preferred route is to the left of a starboard bifurcation daybeacon, which features a reflective red triangle on a white diamond, with a red border. Similarly, a green reflective square on a white diamond with a red border (port bifurcation daybeacon), indicates that the preferred route is to the right. These daybeacons provide directional assistance when navigating across long reaches (e.g. Rideau Lakes), or at junctions where the main channel may not be clearly defined.

LATERAL BUOYS

Starboard Hand Buoys are red-coloured with a pointed top, and mark the starboard (right) side of a channel or the location of a danger. They should appear on your starboard side when boating in an upstream direction.

Port Hand Buoys are green-coloured with a flat top, and mark the port (left) side of a channel or the location of a danger. They should appear on your port side when boating in an upstream direction.

Hand Bouys

Bifurcation Buoys, both starboard and port, mark the points where a channel divides when boating upstream. The top colour on the buoy indicates the correct side on which vessels should pass to stay in the preferred or main channel. If the top colour is red, boaters should keep this buoy on their starboard side if they wish to stay in the main channel. If the top colour is green, boaters should keep this buoy on their port side if they wish to stay in the main channel.

Fairway Buoys are coloured red and white in wide vertical stripes and mark a landfall, channel entrance or the centre of a channel. They may be passed on either side but should be kept to port when proceeding in either direction.

BUOYAGE REVERSAL

The summit of the Rideau Canal is at Newboro. Water flows downstream to Kingston and Ottawa from here in both directions. As a result, the red and green buoys will be on opposite or reverse sides of the channel after you pass through Newboro Lock in either direction.

Balsam Lake is the summit of the Trent-Severn Waterway. Water flows downstream to Lake Ontario and Georgian Bay from here in both directions. As a result, the red and green buoys will be on opposite or reverse sides of the channel after you pass through the Kirkfield Lift Lock in either direction.

To avoid confusion, consider the following rule for navigating the Rideau Canal and Trent-Severn Waterway. Red buoys on your right when going upstream.
