Meet the site
The Canoe Barge is the outermost of the Long Reef barges, 3.5 nautical miles off the headland according to Sydney Dive Charters, and it takes its name from its shape: instead of the blunt, square ends of a standard hopper barge, both bow and stern taper to a point like a canoe, a design used for towed barges that had to be handled in a seaway. The operator describes it as fully intact, with deck winches still in place, and singles out the 'large schools of jewfish' frequently found in its hold as the reason to dive it. Its history is otherwise undocumented; it was presumably one of the Maritime Services Board or contractor hulls disposed of on the artificial reef ground between 1976 and the mid-1980s. It lies on sand at 45–51 m, the deck around 45 m, and because it is intact and well out on the clean-water side of the reef ground it is one of the more photogenic of the barges, with sponges and anemones on the winches and rails and kingfish patrolling above. The hold is the feature: on a good day it is a moving wall of mulloway, and looking in from the hatch coaming without descending into the silt is the recommended approach. Bastard trumpeter, bullseyes and nannygai are the other regulars. Distance puts it at the end of the technical charter's range; the run is close to an hour from Manly, surface current is more likely than on the inshore wrecks, and the dive is strictly a decompression profile on trimix or well-planned nitrox with a drifting station. It suits experienced technical divers completing the Long Reef set, and it is a fish dive as much as a wreck dive. As with Barge 656, Sydney Dive Charters' page is the only published account and the position is held by the operator.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Canoe Barge (Long Reef) is recorded as Wreck in Sydney Northern Beaches. The listed access is boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
Questions, answered
Is Canoe Barge (Long Reef) suitable for my certification?
The record lists Technical (decompression). That does not establish suitability for every route or day. Share your training, recent experience and equipment needs with the operator and ask about the specific proposed dive.
Can I book Canoe Barge (Long Reef) through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
