Inshore Passage:

• Timing is key: Arriving at the Bill at or near slack water (when the tidal current reverses) is crucial for minimizing the impact of strong currents. 

Be vigilant:

Watch for lobster pots, which can be submerged by strong currents. 

Avoid the race:

The Portland Race is a notorious area of strong currents and can be dangerous, particularly during spring tides. The inshore passage offers a safer route by staying closer to the shore. 

Close the coast:

During the inshore passage, it’s advisable to approach the Bill close enough to be “hit by a pebble” from the rocks, but be mindful of the strong south-going currents. 

Be aware of shoals:

The Shambles Bank is a shoal on the eastern side of the race and should be avoided when taking the inshore passage. 

Offshore Passage:

• Requires more space: The offshore passage requires a larger distance of 3-7 miles from the Bill. 

More exposed to wind and waves:

The offshore passage can be more challenging in strong winds and rough seas. 

Avoid the eddy:

Once rounded, a strong eddy sets up in West Bay and returns into the race, so a course westward into Lyme Bay is recommended. 

General Advice:

• Check tide timings: Use tide charts and tables to determine the best time to round the Bill with the current in your favor. 

Consider the wind and sea state:

Choose the passage that best suits the weather conditions and your comfort level. 

Keep a good lookout:

Pay attention to the shoreline, other vessels, and potential hazards like lobster pots and shoals. 

Communicate:

Use VHF radio to communicate with other vessels and the Coastguard.
