What should I know about navigating from Wide Bay Bar to Tin Can Bay in Queensland?

The passage from Wide Bay Bar to Tin Can Bay is navigable for suitable sailing yachts and motorboats, provided Grace has enough clearance through the current channel and you choose a suitable weather and tidal window. The exposed bar crossing is the main challenge; inside, the route to Tin Can Bay is more sheltered, but shoals and tidal streams still need close attention.

Check draught and entrance conditions

Start with Grace's loaded draught, her reliable cruising speed under engine and the latest local entrance advice. A boat drawing 1.2 metres has different options from a fixed-keel yacht drawing 2 metres. Another boat's successful crossing proves nothing about your own clearance.

Sandbanks shift on Wide Bay Bar. An old chartplotter track or coordinates from a cruising blog are not enough. Before leaving, check:

• Current Maritime Safety Queensland notices to mariners and available entrance survey information.
• Updated charts covering Wide Bay Harbour, the southern Great Sandy Strait and Tin Can Inlet.
• Bureau of Meteorology marine forecasts, swell forecasts and tide predictions for the relevant locations.
• Recent observations and crossing advice from the local Marine Rescue service.

Ask about the recommended approach, reported shoaling and how local crossing advice relates to published tide times. Local observations help you interpret the forecast, but conditions at the entrance govern the decision.

Time the bar crossing

For a first crossing, aim for daylight, good visibility, light winds and low swell, at the tidal stage recommended locally. A rising tide towards high water commonly provides useful depth and avoids the strongest ebb. High water, however, does not automatically mean slack stream at the bar.

An outgoing stream meeting incoming swell can produce steep, breaking seas. Long-period swell can break heavily even when the forecast height is modest. Assess swell direction and period as well as wind speed.

Allow time to observe the entrance from a safe position outside the breaking water before committing. If waves are breaking across the advised channel, or you cannot confidently identify the approach, wait offshore in safe water or use your planned alternative. A favourable tide is no reason to press on.

Everyone should wear a properly fitted lifejacket for the crossing. Secure loose gear and close hatches.

Follow the Tin Can Inlet channel

After crossing the entrance, continue through Wide Bay Harbour and follow the charted channels towards Tin Can Inlet and Tin Can Bay. Your track depends on the current entrance alignment and your destination berth or anchorage. A straight line between the bar and town risks taking you across shallow banks.
