Brockville is a freshwater wreck-diving base rather than a tropical reef destination. Local Abucs scubA Charters runs conventional dive boats from St. Lawrence Park in Brockville and Andress Boat Works in Rockport. Parks Canada endorses the Thousand Islands as a wreck-diving region, but depth, river flow and shipping traffic vary by site. Start with the shore-based Centeen sculpture park or an appropriately selected Canadian wreck; reserve deeper current-exposed wrecks for trained divers. This guide intentionally excludes U.S.-water sites and separate Picton/Lake Ontario services.
Centeen Memorial Dive Park
A Brockville shore dive among artificial statues and underwater learning structures, promoted as novice level at 10.7 m to 12.2 m.
Robert Gaskin
Historic wooden barge near the Brockville shore; operator lists 15.2 m to 21.3 m and warns of boating, current, silt and fragile structure.
Lillie Parsons
Historic sailing vessel at Sparrow Island, included in Brockville charters.
Henry C. Daryaw
Advanced inverted freighter close to Crossover Island at around 27.4 m; the operator reports pronounced current and discourages penetration because the interior is decaying.
Operator Checklist
Book a Canadian-water itinerary explicitly rather than simply requesting a "Rockport dive". The same operator site catalogue also markets U.S. wrecks, including Keystorm, America, A. E. Vickery, Jodrey and Oconto, plus separate Picton products. The October 2026 calendar provides evidence of recent departures but is not a guarantee of future capacity. Published individual rates show a Canadian two-dive charter at CAD 135 before 13% HST, excluding tanks and equipment; prices and schedules can change. Ask for meeting dock, shore parking, certification threshold, current strength, gas fills, surface support, required SMB/dive flag, weather cancellation, and emergency plan. No recreational wreck penetration should be assumed safe from marketing images or old site descriptions. Do not infer an available liveaboard from references to multi-day expeditions.
