New Grimsby Slipway
We recently completed a new slipway at New Grimsby Harbour, with significant support from the European Regional Development Fund (ERDF). This slipway has allowed us to greatly improve the efficiency of our maintenance facilities for our fleet of boats operated by Tresco Boat Services.
