Why we moved to Weymouth

Rounding Portland Bill, a headland at the southern tip of the Isle of Portland, involves careful consideration of the strong tidal currents and potentially rough water, especially during spring tides. Sailors can choose between an inshore passage close to the shoreline or an offshore passage further out, with the inshore passage offering calmer water but requiring precise timing and vigilance.
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.
