MARLIN trip up Mersey to Fidlers Ferry February 2019

Thursday 21 February (Liverpool HW 12.20 10.2m). Wind slight then SW 2-3; sunny.

Enter river from marina at 10:37. Calm weather. Sunny. Quite warm. Not at all like February. This was one of the biggest tides of the year - so appropriate for exploring the upper reaches of the Mersey.
Head up Garston Channel. Leave Garston channel at G11 (SHM) and head for waypoints MER0,...MER7. (see
here for navigation info, some history and more photos).
Actually since it was a very big tide, and while it was still making, I could go just about anywhere - so I also used evidence from the surface ripples to try to find the deepest part of the channel.

Cammell Lairds shipyard.

Cross south of Hale Head at 11.35pm and proceed along north bank up to the Runcorn bridges. Go through south arch (of three) of the railway bridge at 11.55. I met a yacht coming down the river just as I approached the bridges. Also a fast SURVEY motorboat (White Osprey) passed me going up river.

Runcorn chemical works

Foot Bridge on the walkway along the north shore at Widnes.

The Rail Bridge and (arched) Road Bridge, looking towards Widnes.

The road bridge is currently being repaired and has workmen on the arch. Follow south bank passing (abandoned) lock into Ship Canal, then head NE keeping close inshore - and avoiding the ruined quay which is an obstacle here (though most probably not when the tide was so high). There was a yellow buoy in place - most probably to mark this obstruction. I had set up a waypoint to avoid it - based on a Google Earth image at low water.

I had been restricted by the trestle bridge (low head room) that was in place 2013-2018 while the Gateway Bridge was built. So my last trip was in 2013. The trestle bridge is finally no more - so I could head on up. Some of the photos taken during construction of the Gateway Bridge helped to give an idea of the location of the deepest channel. I chose to keep fairly close to the Runcorn bank - as on previous trips. I crossed under the bridge using the gap south of the southern large support tower (see LW image).

There were a pair of yellow buoys on the NE side of the Gateway Bridge - possibly to mark the channel (or maybe left-over mooring buoys). I passed under this bridge at 12:05 with current still strongly up-river. I decided to head on up to Fidlers Ferry - calculating that I would have enough time to get back to Liverpool marina by last lock-in (at 2:39pm), if I pushed my speed through the water up from 7 knots (displacement speed) to more like 10 knots to counter the current which would still be flowing up-river until around 1:20pm.

Gateway Bridge

All 3 bridges lined up (looking out).

I passed the pylon crossing and then arrived at Fidlers Ferry at 12:25 (so about 2 hours from Liverpool marina at 7 knots through the water). I had as little as 2 metres under my keel (depth 0.7m) once or twice on the way up - but deeper water is available - I just did not chose to creep up slowly checking depths.
The tide level was high and was lapping against the launching area at Fidlers Ferry. I heard a funny buzzing sound - and popped outside the cabin to see if some engine malfunction was the cause - then I saw a small drone close by. A group of people were standing on the bank - presumably piloting the drone.

Fidlers Ferry Lock

So at 12:29, I had turned around and was ready to head back down river. With 2-3 knots of adverse current, I decide to up the revs - doing 10-11 knots through the water. I was under the Gateway Bridge at 12:50 and under the older bridges (rail and road) at 12:57. It was very calm. By 1:14pm, I was passing Hale Head and I was in good time since the current was slack by now and it usually takes me about an hour from Hale Head to the marina.

Flying a kite - Otterspool Promenade.

At 1:45 I was off Garston and the outgoing current was now 2-3 knots. I noticed a new vessel (or part of a vessel) on Cammell Laird's slip in front of the southern "shed" - presumably placed there after the Red Kestrel IOW Ferry was "floated off" a few days ago.
I entered the marina lock at 2:12, along with White Osprey.

MARLIN trip up Mersey to Warrington April 2019

Thursday 18 April (Liverpool HW 11.10 9.5m; LW 18:13 0.6m)[Gladstone Dock Tide Gauge actual values: HW 11:02 9.46m; LW 18:08 0.66m]. This is an above-average spring tide - an exceptional or equinoctial spring. Wind ESE 3-4; watery sun, visibility about 1 mile.

Enter river from marina at 9:47 after a slight delay from workmen checking repair work to lock. Only one other boat left in that lock. Head up Garston Channel. Leave Garston channel at G11 (SHM) and head for waypoints MER0,...MER7. (see here for navigation info, some history and more photos).

With the strong tidal current (3 knots mostly), I made good progress at only 7 knots through the water (my efficient displacement speed). Off the airport I was overtaken by a survey Cat speeding up to survey the area around the new Gateway ridge.


By 11:06 I reached the Runcorn Bridges and passed under the southern arch and then followed the south shore - keeping inshore of the ruined quay which is an obstacle here (though most probably not when the tide was so high). I then passed under the Gateway Bridge and around Hempstones Point to Fidlers Ferry. Even though I had the data from my trip earlier that year, I still failed to find the deepest channel in places - but the tide was deep enough that I always had a metre or more under my keel.

Liverpool Bay Falcon from Fidlers Ferry Sailing Club:

I reached Fidlers ferry at 11:33 with a strong upriver current (3-4 knots). As well as the Falcon dinghy, there were some small motor boats and ribs out on the river. From now on, I was in territory that I had not explored since 2013. Since I was not planning to make it back to Liverpool Marina in time for the last lock on that tide at 13:25, I could afford to explore further up the river.

As on my 2013 trip, I again found it difficult to locate the deepest channel in the turn to port into Penketh Reach [in 2013 I ran aground, this time I kept 0.9m under my keel here on the way up].

At 11:41 I passed the entrance to Sankey Brook and the tide was rushing up the brook. This brook was, initially, the route taken by flats to reach the Sankey Navigation at Sankey Bridges. The brook proved hard to negotiate - so the Navigation was extended to Fidlers Ferry with a lock directly into the Mersey.

Entrance to Sankey Brook:

Then it was "run the bridges" time:

Forrest Way Bridge (a garbage truck stopped to look at me as I passed under it on my way back)[there are plans to build a bypass bridge alongside this in a year or two]:

There were several branches and logs floating in the river near Forrest way Bridge.

Pipe Bridge (also has footpath):

Image of Bank Quay in 1928 with barges moored, also showing earlier transporter bridge (built 1905, sited near where the pipe bridge is now, demolished 1960s). A second transporter bridge was built in 1915 and, though disused, still stands:

Transporter Bridge; and suspended "car":
 

I reached the Transporter Bridge by 11:50 with still 3-4 knots current up river. I had taken the precaution, unlike in 2013, of lowering my radio aerial and so my air draught was reduced to 4.0m. Also by studying my photos of the next bridge, and some local information, I estimated that I would be able to pass under it. So this time I decided to head further up. I drifted slowly under the box girder bridge and had a foot or two clearance at that tidal height.

Box girder Bridge:

From now on, I was in territory new to me. The next bridges were two railway bridges close together. The first one had plenty of air draught for me, but the following one (stone arch bridge known as Walton 12 arches that carries the main West Coast railway line) was not so easy to assess since there was little room to manoeuvre near it. I decided not to risk getting stuck, or bashing some of the equipment on my cabin roof, and turned round under the first (iron girder) railway bridge at 12:00.

The First Railway Bridge encountered.

The stone built 12 arch Walton railbridge (built 1837 and carrying the electrified West Coast main line):

If I had passed under the stone railway bridge, I would have come to the abandoned Walton Lock. This, until the 1980s, provided a link for barges from the Manchester Ship Canal into the Mersey and hence, following my route, to Bank Quay at Warrington which had unloading facilities. So these barges must have been able to get under the bridge.
  I have found evidence that the rail track over the stone railway bridge (Walton 12 Arches) is at 12.3m above OD, so 6.7m above the sea level at MHWS. If the bridge is 2.3m thick at the centre of the arch [a guess based on photos], then air draught at MHWS would be 4.4m. This checks with a Peel Ports recommendation of bridge clearance at 10.5m above OD [4.9m above MHWS] for any additional bridges that are planned in this part of the river.

I thought that very few sea-going vessels would have come this far inland since the 1980s. I was surprised, however, to see evidence that restoration work on the river bank and on Walton Arches Bridge Piers in 2013 had involved several dumb barges and a workboat. See here.

In order to make reasonable progress against the inrushing tide, I upped the revs to do about 9 knots through the water: resulting in only 8 knots over the ground, if I kept out of the areas of strongest current. I reached Forrest Way bridge by 12:11 and Fidlers Ferry by 12:25, by which place and time, the tide had turned and was favourable (ebbing), and I was doing 9-10 knots over the ground.

Runcorn Bridges:

After passing through Runcorn gap (at 12:50), I was approaching an area of strongly falling tide (at Hale Head HW is 30 minutes after Liverpool: so circa 11:40). I kept up the revs to get through this area before the tide fell further. By 1:06, I was passing Hale Head [local HW+85'].

Hale Lighthouse (abandoned)

I was able to use my surveys to cross Hale Sands and get around to the Garston Channel. I was off Liverpool by 2:00. So 2 hours from my point of turning.

Distance run 39 nm (so 19.5 miles up and back to marina). Average speed 9.3 knots over the ground.

I was too late to lock into the marina, as I expected, so I took the opportunity to do some low tide exploration of the Rock Channel, wrecks on Hoylake beach and the Training Wall.

First, to complete the cruise of the Mersey from head of navigation to mouth: I made for New Brighton, where the Rock Lighthouse (disused) marks the mouth:

I then passed through the Rock Channel and headed along the north Wirral coast towards Hoylake to take a look at a wreck on the beach. At 3:23, I was within 0.22nm of it (due north) and could see that the sand around the wreck was just awash. This, with tide gauge data, helped to determine the height of the wreck above CD - which may help in deciding what vessel the wreck actually is.

As it was approaching low water with a predicted height of only 0.6m above CD at 6:13pm, I then returned east, to go through the Rock Channel - to check my waypoints - and then explore the Training Wall - to see how much they actually dried at low water; since I have never, in 30 years of sailing in and out of Liverpool, actually seen any part of these walls. I also planned to anchor in Lagoon to take a break, out of the current, while waiting for enough water for the marina lock to open (around 9:30).

Some images of the training wall near LW (with MSC Messina loading containers; Stena Mersey incoming near C23 buoy):

After exploring the Rock Channel and Murphy's Gut, I decided to anchor in Lagoon. This is the local name of an inlet on the east side of Brazil Bank. At low water, it is protected on 3 sides by Brazil Bank and by the Training Wall on the remaining side. It thus has rather little current and is fairly calm. I anchored at 53°27.11N 3°3.305W at 5:10 (before LW). From here, I could see the Brazil bank, Training Wall and Murphy's Gut and note at what tidal depth they covered/uncovered.

My conclusion, for Brazil Bank itself, is that it is in two parts: the southerly part dries about 3.6m; the northerly part dried 4.0m while the joining part (west side of Lagoon) dries only 1.3m. Note that these results may change as tides, storms etc push the sand around. Note that the chart of this Bank shows data from MDHB surveys from 1988-1997.

As I was at anchor in Lagoon at low water, I was surprised to see a boat coming in through Murphys Gut. It was a small local fishing vessel (registered as LL506; 5.8m long). So I am not the only person who goes through Murphys Gut. It was very peaceful anchored in Lagoon - except for a low rumbling noise from the big ship engines (generators?) coming from the docks on the Liverpool side.

Lock in to Liverpool Marina at 9:30. There was a 4 knot current off the marina at that time - convenient for me since Marlin has a least speed, in gear at tickover, of 4 knots: so I can easily keep stationary in the river off the lock.

Exploration to Hoylake and back from the marina added 24 nm to my distance run: so 63nm in total.

For my results for the Rock Channel and Murphys Gut, updated by this trip, see Rock Channel.

MARLIN trip up Mersey to Eastham June 2019

Thursday 5 June (Liverpool HW 13.14 9.2m). Wind S 3-4; mostly overcast.

Enter river from marina at 11:45. Main reason for trip was to test AutoPilot with new electric hydraulic pump installed. Because wind was from S, decide to hug the Wirral coast for more shelter. So head over to Cammell Lairds shipyard and then proceed up river towards Eastham:

Cammell Lairds: Polar Research Vessel under construction (aka Boaty-Mac-Boaty-Face);

Vessels under repair in Cammell Laird's Dock - RFA Tidespring (grey) at centre; P & O European Highlander (Cairnryan - Larne Ro-Ro Ferry, 163x23m) at right in dry dock.

Survey vessel (Peel Port's Royal Charter 11x4m):

Oil Tanker Stella Theresa (126x21m) inbound to lock at Eastham, with tug:

I reached Eastham by 12:45 and remained close by, since it was sheltered, to eat lunch. Then cross over towards the airport - with increasingly choppy seas. I explored some of the routes I had taken previously to get data on the current depth.

MARLIN trip up Mersey to Eastham, Hale July 2019

Tuesday 2 July (Liverpool HW 11.30 9.0m). Wind SW 3-4; mostly overcast.

Enter river from marina at 10:26. With wind SW, Wirral shore was more sheltered. So head over to Cammell Lairds shipyard and then proceed up river towards Eastham:

Cammell Lairds: Polar Research Vessel under construction (aka Boaty-Mac-Boaty-Face);

Slow moving container ship (RMS Veritas which takes containers from Liverpool up the Manchester Ship Canal to Irlam).

Bromborough Wharf with coasters Fluvius Teign and Wilson Tees alongside.

Vessel Britain alongside at Carmet (ex-McTay) yard [Built Dublin 1910 as Lightship Penguin, 100ft long, for the Daunt Rock station, on the western approach to Cork near where the PS Killarney was wrecked, then converted in 1966 to a sea training vessel Halloween, then converted in 1980 to a 3 masted schooner Arctic Penguin, then alongside at Inveraray as a Maritime Museum until 2015 when it was bought to be restored to a 3 masted motor yacht, to be based at Barrow].

Reach Eastham by 11:07 and head east along shore from there (not charted). Part of this area is called Poole Hall bay/rocks/sands. The tudor Poole Hall (at Netherpool) was demolished in 1938/9 to make way for industrial development (Paper Mill). The area of ground on the seaward side of the Manchester Ship Canal is raised (man-made from the MSC construction and called Mount Manisty) and should be quite wild since access is not easy. Another feature of interest is that the stream that used to discharge into the Mersey near here is now carried in a tunnel (Poole Hall syphon) under the MSC and then reaches the sea.
The depth was quite shallow even a significant distance offshore.

Eventually decide to head across to Hale Point - since the channel there was well known to me.

Head around the shore close in - past reed beds, tank traps and the abandoned quay.

Lattice Perch off Dungeon Point

Pass Dungeon head at 12:13; Garston at 12:45 and lock in to Liverpool marina at 13:10.

Birders on board reported seeing the following during this trip: Cormorants, shelducks, oystercatcher, lapwing, grey herons, lesser black backed gull, herring gull, black headed gull.

19.8 nm run, mostly at 7 knots through the water.

MARLIN trip up Mersey to Eastham, Mount Manisty August 2019

Friday 2 August (Liverpool HW 12.51 9.6m). Wind SW 0-2; sunny.

Enter river from marina at 11:37. Plan to fill in some gaps from my previous surveys. Aim to locate the sandbanks - since, with a big tide, there was no chance of running aground.

Cammell Lairds: Royal Fleet Auxilliaries under repair/refit [two in Cammell Lairds Dock and RFA Tiderace arriving],: (also the red vessel is the new Antarctic Survey Vessel, aka Boaty-Mac-Boaty-Face);

The recent heavy rain has washed a lot of logs down - some were quite big:

I headed for the MSC [Manchester Ship Canal] entrance at Eastham and then followed the MSC route (it follows the shore line) to the SE. This is an image of the outer wall which impounds the MSC, with a gap where a stream can cross under it.

I planned to get as close as feasible to Mount Manisty: this is an artificial hill on the offshore side of the MSC - so inaccessible except by boat. It reportedly has a fair sample of wild life. It seems to have grass/reed on the shore at spring HW. View of Mount Manisty with Stanlow Oil Refinery to left:

Shelduck (fuzzy image):

The wind had dropped completely - so it was very calm. View of Stanlow Oil Refinery:

Incoming jet, approaching Liverpool Airport over me:

After zig-zagging around, I headed back towards Liverpool Marina following the Eastham Channel (though keeping offshore of the buoyed route).

Carmet's shipyard with vessels under repair:

Oil Tanker fest: Sten Idun (144x23m) inbound to Eastham and Eagle Torrance (246x42m) on Tranmere Stage (both with tugs)

Cruise Ship Mein Schiff 5 (295x36m) on the Liverpool Cruise Terminal:

General cargo vessel Pex (91x16m) passing Cammell Lairds inbound to Eastham with several RFA vessels (Tiderace, Tidespring, Fort Victoria) under repair/refit.

Depths (over CD) shown on HO chart - darker is shallower:

From my trips, Google Earth and other sources: it seems that the southern area of the Mersey Estuary is mainly shallow and dries to mud at low water. Several streams and rivers flow into it and they leave meandering channels which are deeper: working west to east
(i) Just west of Mount Manisty is a stream (Pool Hall Brook) that issues from a syphon under the MSC. This syphon was designed to allow fresh water to pass out, but has a tidal flap to stop seawater coming through at high tide.
(ii) Just east of "Stanlow Island" where the tankers berth, the river Gowy issues from a syphon under the MSC.
(iii) The Holpool Gutter emerges further east.
(iv) To far east, near Runcorn, the river Weaver flows into the MSC and then, if the level is too high, pours over the "Weaver Sluice" to enter the Mersey Estuary.

Lock back in to Marina at 1:35

15 nm run, mostly at 6 knots through the water.

MARLIN trip up Mersey to Hale and Runcorn September 2019

Thursday 19 September (Liverpool HW 14.43 8.6m). Wind 0; sunny.

Enter river from marina at 12:57 along with a survey cat Valkyrie. Very calm and sunny day forecast - so aim to check out the upper Mersey again.

Fleet auxilliary vessels at Cammell Lairds:

Two large tankers on the Tranmere berth: Sti Pimlico(184x27m) and Signal Alpha (258x44m):

Liverpool Airport from the Mersey:

Once or twice I was worried by a sudden noise that sounded like my engine was malfunctioning. A quick look outside - and a jet landing or taking off from the airport was the culprit.

The river Weaver flows into the Manchester Ship Canal and then empties through a controllable sluice into the tidal Mersey. This causes a flow which scours a channel from the sluice out to sea. I decided to seek out this channel. It is charted as running close to the southern edge of the estuary initially (also on Google Earth). As it was still 60 minutes before local HW, I could explore without prior evidence. My efforts to get to it were thwarted - I ran gently aground and had to back out and head away. A view of the sluice from the Ship Canal.

Weaver Sluice from the estuary: where water from the River Weaver runs out from the Manchester Ship Canal, near Runcorn:

Another iconic building is the abandoned church at Runcorn Docks. It was built in 1841 mainly for employees of the Weaver Navigation. With the construction of the Manchester Ship Canal and the Runcorn and Weston Canal, it was left on an uninhabited island - only accessible by crossing the lock gates if closed. It was deconsecrated in 1995 and is now in an abandoned state. Another view.

The old Docks church (Christ Church) at Runcorn - overshadowed by industrial buildings:

The abandoned lock gate from the MSC (just south of the church) to the tidal Mersey (just visible with old wooden lock gates behind).

For some views of the abandoned locks etc on the outer wall of the Manchester Ship Canal.

I decided to head on up to Pickerings Pasture - a nature reserve on the NW bank of the tidal Mersey.

Two grey herons on the river bank at Pickerings Pasture.

Canada Geese on the river bank at Pickerings Pasture.

I turned around at 2:35 (local HW-40 minutes) with current still running up river at about 2 knots. Once I had passed Hale Head, the current slackened and then turned favourable.

The obligatory photo of Hale Head Lighthouse:

During this trip. I saw no other boat in the upper Mersey - there were no yachts moored off LSC either.

My tracks (with depths in metres above CD) from this trip and others from 2018-9. From Dungeon Point to Hale Head. Attempt to reach the Weaver Sluice is at bottom right. Pickerings Pasture is at upper right (to left of tracks).

Lock back into Liverpool Marina at 4:15.

22.3 nm run.

MARLIN trip up Mersey to Stanlow and Runcorn October 2019

Wednesday 2 October (Liverpool HW 14.18 9.6m). Wind NW 2-4; sunny periods.

Since the HW level was a metre more than my previous (September) trip, I could explore anywhere that was covered on that trip. So ideal for continuing my survey of the southern (Cheshire) side of the Upper Mersey Estuary.

Enter river from marina at 12:28. The lock was quite full - with "powerful" boats: Navy Reserve HMS Biter and a Police RIB. Also a survey cat, Valkyrie, and two yachts.

Marina Lock with HMS Biter beyond Valkyrie and a Police RIB:

Head up river, towards "Stanlow Island". This is a triangular piece of land between the Manchester Ship Canal (MSC) and the tidal Mersey, close to where the River Gowy emerges from a syphon under the MSC. It has the remains of a monastery and some abandoned buildings of much later date. It also has "laybys" where tankers berth to load refined products from the Stanlow Refinery. It is reached by using a ferry service across the MSC, provided by the Stanlow Refinery.
  Since the River Gowy scours a channel, there is likely to be sufficient depth at HW, if you can find that channel. Google Earth from 2010 shows a deepish channel along the southern shore of the Estuary from Runcorn to Eastham, including Stanlow. By 2018, this channel appears to have disappeared - except for a small section west of the Weaver Sluice (more on this later).
  Images:
 

See also the section off Runcorn in 2015:

There were some large logs floating - presumably washed down by the recent heavy rain. After crossing some very shallow banks, at 1:07 pm reach the deeper channel of the River Gowy, off Stanlow Island.

Stanlow Island (tops of Tankers just visible). River Gowy emerges at left side.

I then headed for the channel of the River Weaver (using Goggle Earth 2018 images for guidance). Again some very shallow banks (but a making tide still, so no worries). By 1:30 I had reached the somewhat deeper channel and then headed in close to the southern shore.

Sheep grazing on the land between the MSC and the tidal Mersey.

The River Weaver enters the MSC and then the water is released (in a controlled way) by the Weaver Sluice (see proposal to operate a hydro-electric power plant at Eastham Locks which would redue the flow over the Weaver Sluice].

Weaver Sluices (closed).

I then proceed upriver, close to the MSC embankement, with a view of the industrial buildings at Runcorn.

Abandoned Power Station at Weston Point (Runcorn; closed around 1998 when the gas-fired Rocksavage plant was built). More info.

Lots of Canada Geese on the embankment:

The (abandoned) lock gate from the tidal Mersey to the MSC (Christ Church spire just visible) with abandoned wooden lock gates:

At 2:05, I then headed across the Mersey Estuary towards the shore near Hale Head, with current still incoming quite strongly.

View of a vessel (Frisian Lady 104x15m, which subsequently left for a port in Finland) at the cement berth in the MSC at Runcorn seen from the tidal Mersey, with the Runcorn road bridge and Fidler's Ferry Power Station beyond:

Head back (west), against the current, around Hale Head and the keep close inshore around the bay between Hale Head and Dungeon Point. This has a deep water channel close to the shore and is a back-eddy at this tidal state, so the current was helping me along.

In the Bay between Dungeon Point and Hale Head: abandoned tank traps and the quay (from the salt works that were once there):
 

Reach Dungeon Point (Lattice Perch) by 2:41 with the current fairly slack. Head west, close inshore, past the wooden perch and the Airport Gantry.

Liverpool Airport Light Gantry:

Proceed past Garston with increasing waves (wind NW 3-4; wind over tide) towards Liverpool Marina.

Two Tankers, Seamuse (180x32m) and Minerva Atlantica (250x44m) on the Tranmere Oil Stage with Cammell Lairds beyond (Fleet Auxilliaries under repair) seen from the Garston Channel:

Further up-river than Garston, I only saw two other vessels: a small survey boat Osprey and a very small RIB. There were 3 yachts sailing back and forth just upriver from the marina entrance.

Lock in to Liverpool Marina at 3:39. 22.3 nm run.

My tracks (using depth over CD using Liverpool tide gauge 30 minutes earlier). The southernmost track is from this trip:

Depths (over CD) of my tracks shown on HO chart - darker is shallower. Also waypoints shown. First plot shows the south shore of the upper Mersey; second plot is the Hale Head - Runcorn area,
 

Soon afterwards the CG helicopter was hovering over the river near the marina and several CG vehicles were about, fashing lights going. A subsequent report indicated that a body had been possibly sighted and it was searched for by several lifeboats and the helicopter, with the Hoylake Lifeboat eventually recovering a body.
Later reports suggest that it may be that of a woman who went missing near Warrington on 25 September.

A record of the depth and track of my voyages are available from teamSurv
