Moorings full
Written by Tyro Sailor | 31st Jul 2022
Unsurprisingly, perhaps, the moorings in St Mary's Pool were all occupied this morning, except for one which was nabbed by another, ill-mannered boat while we were trying to pick it up. (We did think, after the event, of emptying our holding tank in his direction.) Tried unsuccessfully to contact the Harbourmaster on VHF 16 and 14, and by phone (which gives a very unhelpful recorded message).

We then motored round to Porth Cressa which was nearly full of anchored boats, but we managed to find a space to join them. Mainly sandy bottom (although I managed to find a patch of weedy rock the first time) and I was able to watch the anchor dig in. People seem to be anchoring all over the charted cables. Sheltered and pleasant.

There seems to be some measure of 4G coverage on O2 as well, which I'm using to write this.☺

Update April 2022
Written by Don Thomson 3 | 27th Apr 2022
I reviewed these notes in late April 2022. Nothing really changes here; the rocks are still where they were. What does change are the little rules and regs and what you have to pay. There are still no moorings in Porth Cressa so that is free to anchor.

I reviewed these notes in April 2021. The main change is that there are no longer any moorings in Porth Cressa and it is a free for all to anchor.
Communications improvement
Written by yachtman | 30th May 2018
Since I was last in the Scillies there has been a major upgrade in the data speeds on mobile phones.

using vodafone and 3 in 2016 there was only a 3G signal

this year 2018 on Vodafone it is 4G. Havent tried any other suppliers.

I reviewed these notes in May 2018. The prices have changed and the sector light on the end of St Mary's pier is no more.

Update from visit Aug 2017
Written by j2Chula | 4th Sep 2017
The Porthcressa moorings are rated up to 44ft and cost £20 per night. There is ample room to anchor inside (for smaller vessels) and outside the moorings.
St. Marys harbour has 36 yellow moorings for yachts up to 40ft (£18.50) and 10 green moorings for 40ft - 60ft (£24.50)

Update Spring 2016
Written by dononshytalk | 12th May 2016
These notes were reviewed by Don in May 2016. We note that there moorings available in Port Cressa but not sure whether there is still room to anchor inshore of them.
