Hi,

Planning to sail over from Bristol to Cardiff (via Portishead) later this week. I’m fairly experienced but haven’t done any real Bristol Channel sailing since sailing our Sigma 362 back and forth from Plymouth to Bristol a few years back. Cardiff is a new one for us.

Bit worried about the changing depth horror stories in the approach channel and outer harbour into the barrage locks as we draw nearly 1.9m. Read all the posts re: not cutting the corner and staying mid channel on the recommended track - standard muddy river drill. However, I also noted the cancelled NoM stating dredging due to happen this month was cancelled, does that mean you’re now at peak mud! It will be the first proper trip for our 7 year old son so really trying not to freak him out by getting stuck in the mud for hours!

How dodgy is it?

I’m playing it safe by leaving Portishead at HW-1 and crossing from South Middle to drop onto North Cardiff so should easily be into Cardiff between HW+2/+3 and have at least 5m of water.

Also interested in strategy for getting back to Bristol. If it’s not too silted over there I’m hoping to sneak out early enough to make a direct run back into the Avon to reach Bristol at HW. This seems quite doable running east with the tide.

You have your tides all wrong. The flood tide runs up-channel at Portishead considerably after HW; assuming you have a big and well found boat (sigma 362) you should leave portishead on a falling tide HW+2. You are 3 hours from Cardiff (an hour before LW). On neaps you will easily get in with a 2m draft.

We have not kept our boat (1.2m draft) in the area for a few years now but we did this trip any number of times. Pass south of the south mid grounds buoy and south of the north Cardiff buoy. Make for the outer Wrach buoy and pass it to the south, and follow the median line into the small boat channel from the Wrach channel.

Thanks, had noted E going stream at Portishead which I'll hit for the first hour or so, and if it were neaps I'd agree with you wholeheartedly - leave later do it the easy way. Unfortunately Friday morning is very springy so there won't be oodles of water in Cardiff near low water.

With the dredging postponed earlier this month and without recent local knowledge I was planning to push on and get there in the top half of the tide.

i draw 2mtr and at low water springs I get stuck in the mud in the outer lock basin. one hour either side is good, and has the advantage of seeing where the chanel actually is.

last visit at low water this june

They have been dredging recently and the buoys have been off station. On a good day, at LW the buouys sit on the mud in any case.

I would advise leaving before HW+2 to give yourself a buffer and some extra water but best not run aground on a falling tide. If in doubt, sail past and come back up on the rising tide.

If at LW at the entrance then the outer bends should have the deepest water and you send someone to shout the depth guage.

Lock number 2 is closed at the moment. Call Barrage control at the outer wrach cardinal.

I would be aiming for the top half of the tide so maybe even HW-1 lock out

Thanks all. Left Portishead near HW-1 punched tide for a bit and made it into Cardiff yesterday lunchtime with no drama just after HW+2. Saw around 3m under the keel at the tightest bit. To be honest I’d probably do the same again on big springs.

Planning to be a little more adventurous on the way back tomorrow am and leave around LW+2 and shoot straight for Bristol now I have a feel for the channel, and if I do touch at least I’ll float off in no time ��

‘Doing it right’ riding the tide up channel this time so fairly confident of making HW Bristol to lock in, but there’s always the promise of a curry and a day on the cider in Sirens @ Portishead if running late. No bad option here.

Siren's cider is good, "North Street?" £4 a pint!

Where do you go for the curry

PS. Glad you had a good sail, we did our first night time crossing on Friday, locked into Cardiff at 22:00, never seen so much water. Cut the corner and headed straight for the the "preferred channel to starboard" bouy, makes a change from ploughing through the mud!

Never ever risk touching - it isnt a casual matter. There have been boats rolled over as the incoming tide catches them broadside on. A pal touched off Clevedon, dried out on the sands., put out an anchor downtide to pull his bow into the tide as the boat floated off on the flood - and ripped his skeg out before there was quite enough water to float.

Depends where you touch . It can be a non event or it can be nasty.
