Diving notes

Source: Transports Canada and CHS

On the aerial picture on the left, you can see the Chandler’s wharf of Transports Canada which appears on the right on the map below. The picture of the right shows the visible parts of the wrecks.

Behavior to have: protect the wrecks.

The dives are done from a boat (except otherwise). The water current is strong when high winds occur or during low or high tides (except otherwise). Ask to local authorities. The dives are done in sea water, watch your buoyancy. Raise the weight on your weight belt accordingly. A 7.5mm thick neoprene wet suit is mandatory. A dry suit may be more suitable depending of your comfort habits. Water temperature varies around 60°F but with underwater currents it may drop to around 48°F.

It is important to note that if you do your dive from the shore, a dive flag is mandatory. It is important to know that you may encounter lobsters which may have claws as large as a man’s your fingers. Watch your buoyancy otherwise you may sting yourself on urchins. Seals on their side, if you encounter some, like sometimes to play with you... Take note that in case of emergency, the cell phone may not work, please ask and test (phone someone before diving).

Entry points

Note: directions are accurate as possible. It is recommended to go with someone who knows the site.

The marina has a pamphlet giving some historical facts.
