Panther Shoal is a short boat dive off Plymouth Breakwater that blends a shallow shoal profile with temperate reef life and scattered historical debris. The route is easy to read, but the dive still rewards calm-water planning because tide and channel traffic can shape the day. It suits divers who want a compact local reef with character rather than a deep or dramatic profile.

Key Hazards
Safety Notes
Use a surface marker and stay mindful of the channel edge and boat traffic.
Access Restrictions
Boat access is the normal approach, and the channel edge means the dive brief matters.
Legal Notes
Keep clear of shipping traffic and follow charter guidance.
Community notes to help plan your visit.
Scuba Diving
Depth range of roughly 10–19 m makes this a straightforward scuba dive focused on the shoal and seabed finds.
Freediving
Not a freedive-first site; the boat approach and full shoal profile are better suited to scuba.
Snorkeling
Snorkeling is only useful on very calm days; the main site is better seen on scuba.
