Scuba

What It Feels Like

Nanaimo Harbour is a practical base for local two-dive boat trips to the HMCS Saskatchewan, HMCS Cape Breton, Rivtow Lion and natural reefs around Snake Island. Nanaimo Dive Outfitters advertises year-round charters, and Ocean Quest sells Nanaimo day charters from the Vancouver ferry gateway. This is temperate, technical-feeling diving even when the chosen site is within recreational limits. Your currency is cold-water proficiency, certification-specific depth planning and tide-sensitive boat operations, not tropical resort convenience.

Operator Checklist

Contact the operator before buying onward transport. Ocean Quest advertises a CAD $140 plus GST Nanaimo trip with Advanced Open Water, 30 dives and recent cold-water experience, with rentals and air fills excluded. By contrast, Nanaimo Dive Outfitters says its own two-tank charter price includes standard air cylinders and weights, with guiding and some gases extra. The exact booking date, boat departure, tanks, weights, drysuit rental, buddy arrangements, gas mix and rescue plan must be confirmed with the seller. Book shore orientation/drysuit instruction before deep charters if not locally current. External wreck exploration must stay within certification; penetration requires specialist equipment, training and explicit operator permission.
