North Sea: how the place works

Shallow ground and short wavelength turn force six into a sea that works harder than the same force in the Mediterranean. Add tide, gullies and shifting sandbanks, and autumn gales from the northwest running into the German Bight. The storm season starts earlier here than inland and ends later.

North Sea: what breaks there

Ground tackle and mooring lines take harder punishment here than on any inland water, and groundings on the flats are rarely spectacular but expensive: rudder, shaft and keel root. At the berth there is the swell that reaches even sheltered harbours.

North Sea: what this means for your policy

Two points are worth checking in the conditions: whether taking the ground is expressly covered, and what inspection is required and paid for after a grounding. Neither is an exception here; both are routine.
