These Regulations amend the Merchant Shipping (Light Dues) Regulations 1997 by reducing the rate per ton at which light dues are payable from 38 pence per ton to 37 and a half pence per ton and by making a corresponding downward adjustment (£15,000 instead of £15,200) to the maximum amount for any one voyage by a ship where that voyage ends at a port or place in the United Kingdom on or after 1st May 2017.
