Sunday 20 July from Liverpool marina: accompanied by 5 dolphins; dive Alarm (10m viz) and Lelia (7m viz on wreck; less near surface). Sea state slight and no rain. dolphin video

Sat 20 Sept from Liverpool: to avoid poor viz from dredging near Liverpool; we went quite far west: Penrhos (3-4m viz) and Ocean Monarch (5-6m viz). These sites are shallow enough that the seabed is well lit. Weather N 2-3 and mainly overcast.

Thurs 2 Oct: sunny with mainly very light wind. Ocean Monarch (5-6m viz) and Calcium (3-4m viz). These sites are shallow enough that the seabed is well lit. Lots of marine life.

I note that the giant dredger HAM 316 is (from AIS tracks) dumping both at site Z (near yellow spoil buoy due N of Q1 buoy) and at the site close NE of Hamilton rig. This latter site is close to wrecks Munster, Stanleigh, El Oso.

MARLIN dives 2017

Liverpool based trips need weather to be stable and HW to be between 5am and 9am. I will contact e-mail list a few days before a possible trip. I have pruned this e-mail list to people who have been out with me during the last few years. If this does not apply but you still want to be included - please e-mail a request to me.
As well as the agressive dredging to widen and deepen the shipping channel for huge container ships, construction work is ongoing on the Burbo Bank windfarm extension: involving lots of seabed activity. (Scheduled to be complete first quarter 2017 according to DONG
website). So dive sites nearby (such as Lelia) may have worse viz than recently.

Wed 19 April [trip on another boat]: calm, Lelia viz 2m or less.

Sunday Oct 1 proposed.
Actual data: wave height at Liverpool Bar reached 1.24 metres by 3:30 pm BST. So correct call to have cancelled.

Sunday 15 October.
SSW 4 gusting more, sunny, 1.0m waves at Bar - 2 ft waves where we dived. Two porpoises seen.
  Obstruction NE of North Hoyle Windfarm (close SW of anchoring area, charted as obst 15.2; sonar image): viz 3m, large pipe found. Some of Paul's photos: 1; 2.
  Ceylon: viz very poor (less than 1 ft).

MARLIN dives 2018

Agressive dredging and windfarm construction has ceased - though some dredging and aggregate extraction is still taking place. Let's hope the viz has returned to previous good levels...

Sunday 8 April. Calm and partly sunny. Seals and dolphins seen. After securing permission from CADW, dive on the RESURGAM at low water, viz 3m or so. Sonar trace from RESURGAM.

MARLIN dives 2020

Monday 14 September: "socially distanced" trip with 4 divers to shallow wrecks newly found north of Hoyle bank.
Three wrecks dived (two most probably for the first time ever) - viz not great (1 metre or so) but shallow so not too dark. Current < 0.5kt for 3 hours. Two seem to be wooden sailing flats carrying bricks / limestone; other is a small steam vessel - with a prominent boiler. Weather brilliant.
Details here.

Sunday 27 September: "socially distanced" trip with 3 divers to shallow wrecks newly found north of Hoyle bank plus Lelia. Wind light, sunny, cool, 1-2ft swell from N.
Two more new shallow wrecks dived: one with metal components, one with only stacks of slates remaining. Viz poor (less than 3 ft). Details here.
Lelia dived at slack (and after) - viz better, but still only about 5 ft.
  Some images (from GP) blennie, brown crab, wind farm.
  Video of Lelia dive(Graeme P).

MARLIN dives 2021


Liverpool based trips need weather to be stable and HW to be between 5am and 9am. I usually wait until BST begins. Current COVID restrictions make any 2021 trips uncertain. I will contact e-mail list a few days before a possible trip.

Repairs to Liverpool Marina sea lock have been delayed - and current advice from CRT is that operation will only restart in mid-May.
