DEDICATION
These notes are dedicated to the memory of Joan Abrams (1927-2009), a founder member of the Dinghy Cruising Association (DCA) and for many years editor of the DCA Bulletin. Joan grew up in Heswall on the Wirral shore of the Dee estuary and spent her formative years sailing here with her father before the Second World War. She loved the Dee estuary and attended DCA rallies here almost until she was 80. Her own explorations of the Irish Sea by small boat ranged west around Anglesey and Lleyn, north to the Solway Firth, and across the sea to Ireland, and the written descriptions of her voyages greatly inspired my own sailing. |

Liverpool Bay lies in the eastern corner of the Irish Sea where Wales meets Lancashire. Into the Bay disgorge two significant river estuaries: the Mersey, which gives access to the port of Liverpool, and the Dee, which once gave access to the now land-locked ancient Roman city of Chester. Between the two estuaries lies the Wirral peninsula. The area is dominated by enormous tides, which can range in height by as much as 10 m (33 ft) at the mouth of the Mersey and can generate modest tidal bores in the narrow reaches of the upper estuaries. When the tides ebb they expose huge areas of flat sand & mud. This poses a challenge to the small boat sailor in that, throughout the whole region, launching & recovery by trailer is restricted to within about two hours either side of high water (HW+/-2h) (unless you can find a tractor to tow you across the beach,) and furthermore, once out on the water, access to sheltered anchorages is limited to the same extent. Once you are out at sea between tides, therefore, you are committed, and little shelter can be had before the next HW. So these are exposed coasts and careful consideration must be given to the weather, especially if the wind is likely to be onshore.

The Dee estuary, some five miles wide at its mouth and more than twice as long, divides the Wirral peninsula of north west England from the coast of north Wales. The estuary dries extensively and drains to the sea by two deep channels: westward by the Wild Road and the Welsh Channel around the Point of Ayr, and northward by the Hilbre Swash off the Wirral shore. Between these lies the West Hoyle Bank, the highest patch of which lies west of the HE4 (green) Hilbre Swash buoy. Here, the bank starts to dry at HW+3.5h, and a colony of grey seals hauls out to bask on the sand.

Hilbre is a tidal island situated at the extremity of a sandstone outcrop that protrudes north-westward from the Wirral shore. It is connected to its smaller neighbours Middle Eye and Little Eye by drying reefs. The islands are cut off from the shore within about HW+/-2h. From the high patch west of HE4, the West Hoyle Bank slopes away northward and can be crossed within HW+/-3.5h north of a line between the Hilbre Swash buoy HE2 (green) and the Point of Ayr lighthouse at the northern extremity of mainland Wales (white tower, disused). The only hazard to avoid in this vicinity (apart from the drying banks) is the wreck of the Nestos (see below), which is awash at half tide. |
Hilbre Swash buoys HE2 and HE3 (green) mark the eastern extremity of a spit protruding from the West Hoyle Bank, around which the Hilbre Swash turns a dog-leg. The tide runs within the Swash around the end of the spit and joins the main tidal stream running E-W along the coast north of HE2. Boats sailing from the NE into the estuary against the ebb therefore should hug the East Hoyle Bank along the Wirral shore as close as depth allows in order to avoid the foul tide, and the same for sailing towards the NE out of the estuary against the flood. |
The wreck of the Nestos lies on the spit of the West Hoyle Bank due west of HE2. The Nestos was a freighter that grounded in fog during World War II having become separated from her convoy from Newfoundland bound for Liverpool. Boilers and other metal work are exposed at LW and are awash at half tide. Depth around the wreck is about 4 ft at mean LW. The transit HE2 to the Point of Ayr lighthouse clears the Nestos to the south. |
Farther down the Welsh shore at Llanerch-y-mor, the Irish ferry the Duke of Lancaster was driven ashore at HWS and concreted in, to be used for commercial purposes. The scheme failed and now she lies forlorn. The hull is painted white and makes a prominent landmark. Some decades ago it used to be possible to sail to the wharf here at HW. Notably, a crew from Hoylake SC used to sail a gaff cutter, under full sail and running a powerful inboard engine, across the estuary from Wirral, moor up for a pint in the pub, then return all on the same tide. The gutter however is now obstructed. |
