Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
An 1863 double-masted wooden barque, Robert Gaskin offers a compelling glimpse into maritime history, having sunk in 1889 during a salvage operation. Measuring approximately 34 meters long and 8 meters wide, the wreck lies on a firm bottom, bow facing inland about 120 meters offshore.
Its hull is raised 4.5 meters off the riverbed, presenting a significant structure for divers. Penetration is possible through a large visible hole on the side, where an overhead environment remains relatively open, save for some structural beams. Divers exploring the wreck will find sections offering sheltered areas from current.
An anchor also sits approximately 12 meters off the bow toward shore, adding another feature to explore. Descending along the bow mooring line, divers immediately appreciate the scale of this historical vessel and its preserved features, providing a tangible connection to the past.
Popular for its accessibility within recreational depth limits, the site attracts a range of experience levels.

Best Time to Dive
Considering visibility and comfort, warmer months from June to September generally offer optimal diving conditions for Robert Gaskin. During July, average air temperatures reach around 22.5°C (72°F), making surface intervals more pleasant. Rain averages 4.26 mm during July, with September being notably drier at 1.47 mm, which can contribute to better conditions. While overall dive scores remain consistently good throughout the year, these summer and early autumn months typically align with reduced wind speeds, averaging 15.9 km/h (9.9 mph) in August and 14.1 km/h (8.8 mph) in September, which can help calm surface chop and improve visibility. Cooler air temperatures are common from November through March, with January averaging -7°C (45°F). St. Lawrence River currents also vary, impacting how quickly silt disturbance clears and affecting local visibility. Divers should anticipate freshwater thermoclines and plan appropriate thermal protection for year-round diving.

Dive Experience & Conditions
Accessing Robert Gaskin can be done by boat charter from Brockville, with a descent line guiding divers directly to the wreck. Boat dives typically offer a straightforward entry and exit. A gentle current often runs across the wreck's deck, which can become stiff depending on conditions. Shore diving is also an option from Brockville, though it involves a 20-minute swim out. Such a route places divers beneath a recreational boat traffic lane, necessitating specific protocols as if in an overhead environment. Site visibility generally ranges from 6-12 meters, though local silt disturbance, particularly from other divers, can temporarily obscure features. A firm bottom composition with a light silt layer is present and can be easily stirred up. Divers should be mindful of their buoyancy to prevent reducing visibility for themselves and others.
Dive Difficulty & Safety Guidelines
Navigating Robert Gaskin requires awareness due to its proximity to a busy shipping channel where small boats are frequently present. Surface marker buoys and careful ascent procedures are vital for boat traffic avoidance, especially when shore diving. A descent line is typically available for boat dives, important given potential for current. For shore dives, an extended swim out and overhead boat traffic lane necessitate treating the dive as an overhead environment. This type of route requires additional air and prerequisite training, often involving double tank setups to ensure ample air supply and redundancy. Silt disturbance, with fine particles easily stirred from the bottom, is a factor that can impact visibility. Current can vary from mild to stiff, requiring proper finning techniques.

This gear list is based on verified equipment signals for Robert Gaskin, Canada. Always confirm final gear choices with your dive operator, guide, or liveaboard.
Recommended Dive Suit
Forecast confidence is somewhat lower, with potential for varied conditions ahead. A significant temperature drop is forecast; strongly suggest bringing a backup warmer suit option. A hood or vest can noticeably improve warmth during longer dives.
Based on regional estimates and current weather, the likely required exposure protection is a 3mm wetsuit. Note that local currents and upwellings can alter this. A hood or vest is suggested for sensitive divers due to surface winds.
Because recent water temperature readings are not available for Robert Gaskin, the guidance below is based mainly on current air conditions and seasonal expectations. Current surface air temperatures are roughly 28°C (82°F).

Marine Life at Robert Gaskin
Acting as an artificial reef, Robert Gaskin attracts various freshwater species. Looking into the hull, divers often spot sunfish and bass spawning within its sheltered confines. Eels use the wreck's crevices for cover, establishing ambush points for prey. Around the stern, younger walleye gather, benefiting from the structure. Predators, such as larger fish, patrol the wreck at night, utilizing its contours for hunting. Despite limited detailed data, divers commonly report observing these patterns of fish activity, making it a lively underwater habitat.
