Shotline Diving Wreck Profile

• Name: Dart
• Former Names: Nil
• Registration Number(s): Not listed in known registries
• Date Built and Launched: Pre-1844; exact year unknown
• Measurements: Not detailed, but consistent with early 19th-century canal steamers; estimated 15–20 m (50–65 ft) in length
• Date Lost/Incident: 1844

Vessel Type

Steam-Powered Passenger and Cargo Vessel
Operated on the Rideau Canal system, facilitating transport between Kingston and Ottawa and possibly through adjacent river routes.

Description

The Dart was a typical mid-19th century wood-hulled steam packet or tug-type vessel operating in the early days of commercial navigation on the Rideau Canal. Like many of its contemporaries, it carried passengers and light freight through the growing inland waterway system of Upper Canada.

History

During the summer of 1844, Dart suffered a catastrophic boiler explosion, a tragic but not uncommon fate for early steam vessels lacking rigorous engineering oversight. The explosion occurred while underway, instantly killing a young boy named Willis, reportedly only 15 years old, and injuring several others, including crew members and passengers.

According to historical inquest testimony led by Coroner Gavin Russell, the root cause of the explosion was traced to:

• Severely corroded boiler components
• Excessive operating pressure beyond safe engineering tolerances
• Incompetent or untrained engineering crew, a recurring issue at a time when qualifications for steam operations were lax or nonexistent

The findings triggered some of the earliest calls for professional certification of engineers and standardization of vessel inspections in Canada.

Final Dispositions

• The wreckage was reportedly salvaged in parts. It is unclear if Dart was rebuilt, scrapped, or repurposed under another name.
• No records indicate the vessel was recovered as a whole or returned to service.

Located By & Date Found

• Discovery/Recovery: Nil
• No remains have been located, and the exact site of the explosion has not been archaeologically confirmed.

Notmars & Advisories

• Obstruction Status: Nil
• Navigation Charts: No known current obstructions attributed to Dart remain on Rideau navigation charts

Conclusion

The loss of the Dart marked a critical point in public awareness of steamship safety. It catalyzed calls for boiler inspections and formal engineering training. Though no physical wreck has been located, Dart remains emblematic of the transitional, often dangerous early years of powered inland navigation in Canada.
