Key Dive Site Facts
Dive Site Overview
Exploring Brunswick offers an immersive dive into an 1805 English East Indiaman. Originally about 40 m (130 ft) long and 13 m (43 ft) wide with three decks and thirty guns, the vessel met its end near Simon's Town.
Today, wreckage lies broken up and partially buried in fine sand. Divers can observe structural remnants, including a prominent keelson, sections of the copper rudder strap, and iron knees, which indicate its original formidable construction.
The site's shallow conditions, reaching a maximum depth of about 6 m (20 ft) and an average of 4.5 m (15 ft), ensure excellent light penetration across the debris field. Heavy kelp and other seaweeds now thoroughly encrust the historical timbers, creating a dynamic, living habitat.
This is an archaeological site, protected by legislation, meaning no disturbance or removal of artifacts is permitted, ensuring its preservation for future explorers.
Best Time to Dive
For the most favorable experience, consider diving Brunswick during periods with reduced wave action and clearer conditions, which often occur in cooler months. While climate data generally indicates 'Poor' to 'Moderate' dive scores throughout the year, historical reports suggest winter dives at low tide can yield better visibility, despite higher average wave heights (e.g., July averages 3.25 m / 10.7 ft). Air temperatures during winter months, like July, average around 12.9°C (55°F). Conversely, April and May often present 'Moderate' dive scores with milder air temperatures, averaging 16.7°C (62°F) and 15.4°C (60°F) respectively, and slightly lower average wave heights (April averages 2.43 m / 8 ft). Water temperatures have been reported around 15°C (59°F). Conditions ultimately vary; planning for calm days is essential, even though the site is somewhat sheltered.

Dive Experience & Conditions
Your dive at Brunswick can begin with either a shore entry via rocks or a small beach, depending on the tide, or a boat entry. From shore, divers typically swim out around 120 m (130 yards) to reach the wreck. Topography reveals a fine sandy bottom where much of Brunswick's wooden structure has broken up and lies partially buried, often shifting with seasonal weather patterns. Visible sections are heavily overgrown with kelp and various seaweeds. Maximum depth for this site is approximately 6 m (20 ft), allowing ample natural light to reach the wreckage. Visibility is usually moderate, and while seldom excellent due to its inshore position, the shallow depth significantly improves overall brightness underwater.
Dive Difficulty & Safety Guidelines
Diving Brunswick requires adherence to specific guidelines to ensure safety and preserve this significant archaeological site. As it is situated within the Table Mountain National Park Marine Protected Area, a valid permit is mandatory. Additionally, divers must contact the SA Navy Ops Room at 021 787 3818 to request permission and provide dive duration details. Wreckage is a legally protected archaeological site; therefore, disturbing, touching, or removing any part of the wreckage is strictly prohibited. Given its shallow nature and proximity to shore, it's generally accessible for divers with basic open water certification, but respect for the fragile historical remains is paramount.
