This page merely provides some photographic views of each location, plus supplementary notes.

Note when approaching the Anglesey coastline, that there is much traffic using and joining/leaving the traffic separation scheme from movement to and from Liverpool.

Follow the rules for TRS schemes, i.e. cross on a perpendicular heading to the direction of travel along the lanes. During 2003, have noted commercial shipping not following the spirit of the rules - e.g. recently found a ferry heading E on the northern limit of the west going lane in thick fog.


Holyhead can be entered in all weathers. There is a traffic separation scheme to be negotiated off Anglesey's NW coast.

The harbour and marina are exposed to winds from the NE. Though there is an outer pontoon breakwater, there will still be significant movement of boats in their berths during a fresh NE breeze.

As at Jan 2003, marina office, chandlery, and women's & men's toilet/showers located in portacabins. Hard standing and boat repairs. Fair sized town.

Possible also to pick up a mooring outside the marina belonging to the local sailing club.

Cemlyn Bay

Provides shelter from SE through to W. About 7m out of tidal streams. Bay lies close W of Wlyfa nuclear power station.

Approach waypoint: Cemlyn bay, 53 25.40 N, 4 30.00 W, just north of mouth of bay - close to Harry Furlong green lateral.

Cemaes Bay

With Cemaes bay shelter can be found from NE through S round to W, in a number of anchorages within the bay. The view above shows a typical first site of the bay for a yacht which has sailed from Douglas and just crossed the Traffic Separation Scheme. Wlyfa power station is situated on the headland forming the western side of Cemaes Bay.

Note shoal on east side of the mouth of the bay - which may be a hazard below half tide.

Approach waypoint: Cemaes, 53 25.40 N, 4 27.70 W, Off mouth of bay, but west of shoals off Llanbadrig Cove on east side.

The anchorages within Cemaes Bay are described below:

Lamb Island

Anchor to south or E of the island. Power station stands large in the background. Pebble beach. Disused slip near Lamb island, disused boat house. Care re pots with floating pick up lines of 15ft or so (02/08/03). Footpath on southern end of beach leads upwards to lead through a wall. Take path leading inland (roughly SE) to follow easy paths to road. Leads to a junction, turning right leads to Wlyfa power station visitors centre, turning left leads toward Cemaes village. When the first Cemaes village sign can be seen, there is a sign indicating a coastal footpath. It leads to fields of grazing sheep. There is a turn style in the wire barbed wire fence which gives access to Porth-y-Wlyfa. Path at west end of latter, if you have legs long enough to get over the wire fence, provides access to an open field with easy walking of short distance back to Lamb Island anchorage's beach. (Last visited 03/08/03)


Best to examine the cove before use. If you anchor off Lamb Island or off Cemaes, it's not too far to walk round to inspect. Cove has a shingle foreshore, and rocky ledges (particularly extending from eastern side which might not be noticeable if cove approached at HW. Fair number of pots laid in the cove. (Last examined 03/08/03).


The anchorage is just to seaward of the mouth of the bay in which the drying Cemaes Harbour is located. A number of local moorings for small boats are placed here, and there is a buoy advising of an 8 knot speed limit.

Buoy indicating 8 knot speed limit within the bay

Entrance to drying harbour - tide on its way out

View from pier head looking across popular beach

The bay uncovers to firm sand - if you use a dinghy to reach the harbour you will have to carry it back to the waters edge at low tide. As the bay shoals very gradually it is popular with bathers.

The panorama above was taken from the slip in the SW corner of the harbour. Harbour masters home at root of pier. Telephone behind harbour.

A stream enters the south side of the harbour, with a quay located on its eastern side.


The Stag, Ye Ole Vigour pubs. Londis mini market, various other stores, fish and chip shop, newsagents/video/DVD store, antiques, ladies hairdressers (gents by appointment), shop farm, post office, HSBC, Heritage centre/craft/tea room. Woburn Hotel, licensed restaurant and guest house, couple of B & B's. Surgery.

Harbour Hotel incorporating Smugglers Bar and restaurant, general store.

Half way between the anchorage and the drying harbour on the south side of the bay is Pier Back and Cafe (Caffi). Dries before 1918 hrs (i.e. HW+??).


There are proposals for a new breakwater, with a numbers of alternative plans on public display at the route of the existing pier.

Llanbadrig Cove

More rocks in this cove than appears on charts and chartlets. Best to enter for the first  near low water, though cautiously, when more of the hazards can be seen. Provides shelter in NE to E winds.

Hells Mouth/Porth Cynfor

Not one to take your yacht into.

Porth Wen

Bay out of main tidal stream, but watch out for pot buoys on approach. Landing at foot of brickworks straight forward but access to hinterland difficult. Disused brickworks interesting to look over. A site showing views and some of the history of the site

Approach waypoint: Porth Wen, 53 25.60 N, 4 24.00 W, west side of mouth of bay.

Bull Bay

Provides shelter from SE through to W. Sand bottom. Out of tidal stream.

Cove with village lies on west side of bay in which there are moorings for small boats laid between rocks - some of which dry.

Approach waypoint: 53 25.30 N, 4 21.40, off mouth of bay.

Amlwych Harbour

Pens (mini docks) allow fin keelers to remain afloat (if permission given to lie there). The pens are home to two Liverpool Pilot launches, and used  by the local fishing fleet. Otherwise boats able to take the ground may dry out alongside quay in outer harbour the face of which is guarded by substantial fendering. Inner harbour congested with local boats.

As the pilot books mention there is a strong run of tide across the shallowly indented bay in which the harbour lies. Anyhow, the approach straight forward otherwise. In through the pier heads found some "pens" to port (constructed for the benefit of pilot vessels and oil company vessels), and to starboard some quay space, with large rubber sausages to protect boats from the rough walls.

Pubs - nearest the Liverpool Arms. Nearby, a fish and chip shop.

At one time the mines on Anglesey's Paris Mountain were the world's leading source of copper ore. Amlych port served the transportation needs of the mines, as well as being the site of ship building until the size of ships generally became too large for building at the port.

Porthyrysgaw (or Llaneillan)

The approach to Porthyrysgaw, which lies on the west side of Point Lynas. Second view is of the cover tucked away at the head of the bay.

Provides shelter in E through to SW. Bottom mud/sand.

The peace may be spoilt by wet bikes and speed boats which have a habit of using anchor yachts as turning marks. The above shots are a 'panoramic series'.

Public information boards displayed near the beach. They are readable if you double click the images.

Freshwater Bay

Only listed as an anchorage in the Admiralty Pilot. Water deep 17m. Shelter in W'ly winds if you have enough anchor rode to use the anchorage.

Dulas Bay

A broad sandy bay. Anchorage may be found below a prominent house.

Traeth Dulas

A sandy bay. Foreshore dries out a long way. Caravan park on west side of bay.

Royal Charter Bight

Really part of the same broad bay as Dulas and Traeth Dulas. Royal Charter Bight forms the eastern extremity and can provide shelter in SE winds. Note that charts shows a drying wreck, from which the anchorage gets it's name.


A good anchorage in about 3 metres, mud bottom. Shelter okay from S through to W. Notices ashore claim this to be "Britain's friendliest village". Watch out for unmarked sewers lying off beach. Leave area in front of lifeboat slipway clear. Pub, tea room, antique shop, chip shop, provisions. Use an anchor light - as this anchorage is busy and can be approached at night. Anglesey shore nearest Moelfre's islet popular with anglers.

Traeth Bychan

Anchor between the points forming the bay. Holding good. The peace may be spoilt by wet bikes and speed boats which have a habit of using anchor yachts as turning marks.

Redwharf Bay

A large drying bay. Not yet visited.

Pilot's Cove

Temporary anchorage near lighthouse. On the right in the above photo. Holding reported to be poor.

Puffin Island

Anchorage on southern side of islet. Care required to avoid drying ledge extending SE from the island, plus one rocky outcrops near the anchorages. Landing not permitted.
