The rocks of Scilly
Written by maryandtherib | 29th Aug 2016
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.
