New Grimsby Sound and Old Grimsby Harbour offer superb deep water moorings for visiting yachts and cruisers.
Important Notice: 1st June 2020
Tresco moorings are currently closed to visiting boats, and at this time the islands are still closed to overnight visitors. We hope to reopen the moorings on or after 4th July, but please wait for further updates before planning your passage.
When our moorings do reopen, there will be toilet and shower facilities for visiting craft at the Cottage Department near the Island Office. There will be no fuelling facilities on Tresco. There will be access to water and waste facilities on New Grimsby Quay.
Please also note that St Mary's Harbour has issued a Local Notice to Mariners advising yachts and other recreational vessels not to travel to the Isles of Scilly at this time.
Moorings are allocated on a first come, first served basis and cannot be pre-booked, but if we can be of any assistance please contact our Harbourmaster, Adam by email or on 01720 423653 or 07778 601237.
The fee for use of a mooring, including refuse disposal and fresh water, is £20 per night. The mooring fee is collected by Adam on the water, or can be paid at The New Inn, Ruin Beach Cafe and Island Office.

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.
