General Description

Main coverage of the Scilly Isles  HERE

New Grimsby Sound lies between Tresco and Bryher and is a deep water anchorage well sheltered from the East and West but awful in SSE & NNW winds.  For strong Easterlies it is better sheltered than St Mary’s. It is accessible at all states of the tide from the North but only for about a couple of hours either side of HW if entry is made from the South.

We are hearing various reports from skippers about the charges here - to the extent that one skipper was charged £30 for a night at anchor. The island is also saying that there is no anchoring within 100 metres of the shore and no drying out on any of the beaches. We are watching the situation

Thanks Gigae for this info - I've altered the text. I understand the Pirates of Penzance may have relocated!!

No showers at the New Inn
Written by Danny the dinghy | 16th May 2022
We were told that there is no shower available (at the moment?) at the New Inn. There was apparently one near the estate office but we didn’t bother to track it down.

The ‘three nights for the price of two’ has been stopped. The overnight price for a mooring is still £20

No changes but we understand that the helicopter service will be reinstated in 2019
Update Spring 2016
Written by dononshytalk | 12th May 2016
These notes were reviewed by Don in May 2016. No changes, not even the prices. There are rumours that the helicopter flights may be resumed either this summer or next but we think they are still at the "talking" stage
