UPDATE SPRING 2021
Written by Don Thomson 3 | 15th Apr 2021
I reviewed these notes in April 2021. I think our member's note on relying on GPS means the CHARTS on your GPS plotter because, the GPS itself will be accurate but the charts may not have all the rocks on them. Remember to use the maximum zoom if you use Navionics. The Hotel that used to be above Old Grimsby is now holiday apartments. and the hotel on St Martins that laid buoys in Teale Sound is now part of an international consortium and it is not known if they still lay buoys.
The rocks of Scilly

Don't rely on your GPS! There are lots of uncharted bits of rock which are very shallow at low water, particularly around St Agnes where even the locals stick to routes they know. Tidal range can be nearly 6m at spring tide so it's all about the navigating.Some wonderful cardinal markers with bells which remind me of the Inchcape Rock. Some interesting bits of water where the tidal streams meet between the islands, or where deeper more exposed water meets shallow. And lots of wrecks. Lots.
Note St Mary's fuel channel is on 12, and sometimes you have to queue for a while.... take note that they close for lunch. the fuel berth is next to the Scillonian berth, but only has about 0.5m above chart datum at low water.
you can also telephone for fuel on 01720 422431.

Thanks Mary and the rib
