Dive Safety

Cold Water: Fathom Five is classified as “cold water diving.” Plan your dives as if they are 3 m (10 ft) deeper. Adjust buoyancy while ascending and descending.

Physical Condition: A pre-existing medical condition could affect your diving ability. Adjust your dive plans to match your current health limitations.

Never Dive Alone: The even numbered buddy system offers essential safety in the event of difficulty.

Alcohol and Drugs: Being under the influence of alcohol or drugs while diving can have disastrous effects.

Night Diving: Only experienced divers should engage in night diving. Each diver should be equipped with underwater lighting.

Dive Restrictions: Around the harbours, dive only in the designated diving areas, do not dive in vessel channel. 

Around the Tobermory harbours, diving and snorkeling are permitted only in the numbered dive areas, as shown on the map. 

Due to vessel traffic, in the harbours, it is important for each diver to review the park regulations and dive safety information. 

Please ensure extreme caution when diving and operating a vessel near or within any of these harbour areas. Also, please respect the rights of private property owners near these sites. Vessels are not permitted in the Lighthouse Point restricted area at any time.
