Alderney Race and Channel Islands: how the place works

The tidal range is among the largest in Europe, and at springs up to nine knots run in the Alderney Race. With wind against tide a steep, breaking sea builds there that has nothing to do with the reported wind strength. The window for the passage is narrow and fixed.

Alderney Race and Channel Islands: what breaks there

Alderney Race and Channel Islands: what this means for your policy

This is where it shows whether a policy pays for inspection after hard use and whether rudder damage is replaced without a deduction for wear. Both should be settled before a Channel Islands trip.
