PENTLAND FIRTH TO CAPE WRATH
(AC 1954) Dunnet B, S of Dunnet Hd (lt) gives temp anch in E or S winds, but dangerous seas enter in NW’lies. On W side of Thurso B is Scrabster sheltered from S and W. Between Holborn Hd and Strathy Pt the E-going stream begins at HW Ullapool –0150, and the W-going at HW Ullapool + 0420, sp rates 1•8kn. Close to Brims Ness off Ushat Hd the sp rate is 3kn, and there is often turbulence.
SW of Ushat Hd the Dounreay power stn is conspic, near shore. Dangers extend 2½ca seaward off this coast. Along E side of Strathy Pt (lt) an eddy gives almost continuous N-going stream, but there is usually turbulence off the Pt where this eddy meets the main E or W stream. Several small bays along this coast give temp anch in offshore winds, but should not be used or approached with wind in a N quarter.
Kyle of Tongue is entered from E through Caol Raineach, S of Eilean nan Ron, or from N between Eilean Iosal and Cnoc Glass. There is no chan into the kyle W of Rabbit Is, to which a drying spit extends 0•5M NNE from the mainland shore. Further S there is a bar across entrance to inner part of kyle. There are anchs on SE side of Eilean nan Ron, SE side of Rabbit Is, off Skullomie, or S of Eilean Creagach off Talmine. Approach to the latter runs close W of Rabbit Islands, but beware rks to N and NW of them.
Loch Eriboll (AC 2076) provides secure anchs, but in strong winds violent squalls blow down from mountains. Eilean Cluimhrig lies on W side of entrance; the E shore is fringed with rks up to 2ca offshore. At White Hd (lt) the loch narrows to 6ca. There are chans W and E of Eilean Choraidh. Best anchs in Camas an Duin (S of Ard Neackie) or in Rispond B close to entrance (but not in E winds, and beware Rispond Rk which dries).
The coast to C Wrath is indented, with dangers extending 3ca off the shore and offlying rks and Is. Once a yacht has left Loch Eriboll she is committed to a long and exposed passage until reaching Loch Inchard. The Kyle of Durness is dangerous if the wind or sea is onshore. Give Cape Wrath a wide berth when wind-against-tide which raises a severe sea. A firing exercise area extends 8M E of C. Wrath, and 4M offshore. When in use, R flags or pairs of R lts (vert) are shown from E and W limits, and yachts should keep clear.
