SDI Wreck Diver
Your first step in wreck diving certification
SDI Wreck Diver Course in Nanaimo
Wreck diving opens the door to some of the most fascinating dive sites in the world, from historic ships and artificial reefs to purpose-sunk vessels and accidental wrecks. The SDI Wreck Diver course is designed to teach you how to safely plan, navigate, and explore wrecks while understanding the unique risks that come with these environments.
In Nanaimo, training takes place on some of the most well-known wrecks on the West Coast, including the HMCS Saskatchewan, HMCS Cape Breton, and the Rivtow Lion. These large, intentionally sunk vessels provide real structure, real depth, and real navigation challenges, making them ideal training platforms for developing solid wreck-diving skills.
Training in Nanaimo means learning in cold water, often with limited visibility, depth considerations, and changing conditions that demand precision and awareness. If you can plan and execute wreck dives confidently here, you will be well prepared for wreck diving anywhere else in the world.
Why train on wrecks in Nanaimo
Nanaimo is one of the strongest wreck-diving regions on the West Coast. Our local wrecks are large, intact, and purpose-sunk to create safe yet demanding dive environments. They allow divers to practice proper wreck techniques without unnecessary risk, while still experiencing the scale and complexity that defines true wreck diving.
Cold-water wreck diving naturally builds habits that translate directly to warm-water destinations:
-
- Slower, more deliberate movement around structure
- Strong buoyancy and trim control near fragile surfaces
- Clear navigation and line awareness on large wrecks
- Respect for overhead hazards and entanglement risks
Divers who train on Nanaimo’s wrecks often find that tropical wreck diving feels easier, calmer, and more intuitive by comparison.
What this wreck diving course focuses on
The SDI Wreck Diver course follows standards set by Scuba Diving International and emphasizes non-penetration wreck diving. The goal is to make you a capable, thinking wreck diver who understands how to explore safely, not rush into confined spaces.
You will learn:
-
- Wreck history and how different wreck types behave underwater
- Hazards specific to wreck environments
- Safe wreck dive planning and gas management
- Proper finning techniques to avoid silt and entanglement
- Navigation around large structures
- Use of lines and reels for orientation and reference
- Emergency procedures specific to wreck diving
The course focuses on awareness, discipline, and decision-making, not thrill-seeking.
Real-world wreck skills, not theory only
Training dives take place on actual local wrecks where you will practice:
-
- Approaching and descending on wrecks
- Maintaining proper distance from fragile or silty areas
- Swimming exterior routes with clear navigation plans
- Identifying safe zones versus high-risk areas
- Using lines without creating entanglement hazards
- Managing task loading while maintaining awareness
These skills apply equally to artificial reefs, historic shipwrecks, and modern steel structures worldwide.
Penetration and limits
This course does not include advanced wreck penetration. Any swim-throughs are limited to areas where:
-
- You can see natural light at all times
- There are no restrictions
- You remain within recreational limits
This keeps the course accessible while reinforcing the importance of staying within training limits. Divers interested in more advanced penetration are encouraged to continue into technical wreck or overhead environment training after gaining experience.
Who this wreck diving course is for
The SDI Wreck Diver course is ideal for:
-
- Divers interested in exploring wrecks safely
- Divers planning trips to wreck-heavy destinations
- Local divers wanting to better understand Nanaimo’s wreck sites
- Underwater photographers and videographers working around structure
- Divers considering future technical or overhead training
You do not need to be a technical diver to benefit from this course, but you do need solid buoyancy and comfort in the water.
Equipment considerations
Wreck diving places higher demands on equipment awareness. During the course, instructors will discuss:
-
- Streamlining and hose routing
- Fin choices for precise movement
- Redundancy considerations
- Cutting tools and signaling devices
- Exposure protection appropriate for cold-water wrecks
Rental equipment is available, and this course is a good opportunity to evaluate your setup before investing in long-term gear.
Why wreck training here prepares you for anywhere
Wrecks around Nanaimo are deep enough to require planning, large enough to challenge navigation, and complex enough to demand respect. Learning to manage these factors builds confidence and judgment that transfers directly to:
-
- Caribbean wrecks
- Pacific and Atlantic artificial reefs
- Historic wrecks in Europe
- Advanced recreational wreck diving worldwide
Many divers who complete this course locally find that wreck diving abroad feels simpler and more intuitive.

SDI Wreck Diver Course FAQ
What is the SDI Wreck Diver course designed to teach?
The SDI Wreck Diver course teaches you how to safely plan, navigate, and explore wrecks while understanding the hazards unique to wreck environments. The focus is on non-penetration wreck diving, situational awareness, buoyancy control, navigation, and risk management. You will learn how to enjoy wrecks responsibly, not how to push into overhead environments beyond your training.
Do I need previous wreck diving experience?
No previous wreck diving experience is required. This course is designed for certified divers who are curious about wrecks and want structured, safe training before exploring them independently. You should be comfortable with basic buoyancy and open-water diving before starting the course.
Will this course include wreck penetration?
No advanced wreck penetration is included. Any swim-throughs are limited to areas with natural light, no restrictions, and clear exits at all times. This keeps the training within recreational limits and reinforces the importance of staying within your certification level.
Divers interested in wreck penetration training can pursue additional technical or overhead courses later.
Why train for wreck diving in cold water?
Cold water adds task loading that builds strong habits. Managing exposure protection, buoyancy, limited visibility, and depth teaches patience, control, and planning. These skills transfer directly to warm-water wreck diving, where conditions often feel easier by comparison.
Which wrecks are typically used during training?
Training dives are conducted on large, intentionally sunk local wrecks such as the HMCS Saskatchewan and the Rivtow Lion. These sites provide excellent structure, clear navigation opportunities, and realistic depth profiles without unnecessary hazards.
Do I need special equipment for wreck diving?
You do not need full technical gear, but wreck diving does place higher demands on equipment awareness. During the course, you will discuss streamlining, hose routing, fin choices, cutting tools, lights, and redundancy considerations. Rental equipment is available, and instructors can help you assess whether your current setup is appropriate.
How important is buoyancy and trim for wreck diving?
Very important. Good buoyancy and trim help you avoid contact with fragile surfaces, prevent silting, and maintain awareness around structure. The course places strong emphasis on controlled movement and positioning around wrecks.
Will I learn how to use reels or lines?
Yes. You will be introduced to the proper use of reels and lines for orientation, reference, and safety around wrecks. The focus is on clean, controlled use that avoids entanglement and unnecessary complexity.
Do I need to be an advanced diver to take this course?
An Advanced Open Water certification or equivalent is recommended, especially due to depth and task loading. Comfort at deeper recreational depths and solid buoyancy control will help you get more out of the course.
