Nearly undone by moon suck

Then you'd have been wrong,sadly just a bunch of lads & as we swept down the side of that gin palace (people sitting around enjoying the evening,glasses in hand) our boom sheared off their railings like match sticks as the boat swept along the side.Nothing the combined strength of about half a dozen people could do would stop it.(I might have considered pretending that I was'nt the skipper:)
 
Barometric Pressure

Ken started his post regarding strength of current.

Surely providing the Barometric pressure is reasonably constant it does not affect the strenghth of current.


My understanding is that it is the tidal range that causes the current and while Barometric pressure will affect the height of any tide is affects both the low and high tide heights equally.

Or have i got it wrong again?

Was interesting going between the piles and into the entrance channel to Shotley...... at 45° to direction of travel... :)

Actually Neil, I nearly made a ricket of it yesterday, lockmaster said 'come slowly up the approach channel'. Missus said 'why are you going so fast' as I went between the piles, 'because I nearly sideswiped them' I said, i had to go like hell to miss them.
 
The worst tidal situation that i have been in was trying to get into my allocated berth in Benodet marina at half tide on springs, we got into big trouble and received lots of 'mon dieus' and gallic tutting and head shaking.

Last summer we had a few days in Benodet Marina, on the outer pontoon, and there were some horrendous crunches caused by people unused to the strength and direction of the tide. We were lucky because we happened to arrive at slack water so experienced no problems but I made damn sure we left at slack water! :cool:

Boy, the tides were big this weekend. I rowed ashore from mooring at mid ebb. Flowing too fast to row upstream against the mid-river flow, so crabbed across towards the shallows. Unfortunately went too far and ended up grounded. Some futile punting with the oars produced no results. Needed to get out and push back into slightly deeper water. By the time I got back into the boat, reorganised self and oars, and started rowing back upstream the place where I'd run aground was above water and you could see my footprints. If I'd been a tad slower getting unstuck we might have had to sit out six hours stranded, waiting for the water to come back.

Sneaked back up the shallows towards the marina pontoons, got to the critical corner (it's where the downstream end of Mercury marina - which is effectively a bay in the river bank – kicks back out into the Hamble), and was spun out towards the mainstream by at least 5 knots of cross current. Frantic rowing just allowed me to get to the corner of the downstream hammerhead. While sitting there panting a big mobo trying to reverse into a berth just upstream from the corner was also spun out, despite much food processor noise from the bow thruster, so I didn't feel quite so bad.

Conclusion, should have stayed on the boat and had a snooze while waiting for the ebb to lose enthusiasm.

Sitting on my boat on saturday evening, we are the first boat on the pile moorings coming in from the sea. Tide had turned and was well on its way in, seriously fast, water piling up on one side of the pile. We spotted the boats that had patiently waited for water start to come in, BLOODY HELL!! they were being swept sideways on to us!! The first one literally missed us by inches, by then fenders out, help from Roy and Mo next to us and they kept coming, two trawlers came in but the lads had the measure of it and kept clear, then some more yotties, me frantically waving them off at 100 yds and still they were being crabbed on to us. One of them muttered weve been coming here for years as he was swept crab style towards us, hmmm, hadnt done much for his common sense!! Anyway it only lasted for about half an hour and it, relatively speaking, calmed down a bit.
The minus 0.1 a few weeks ago didnt seem as bad as this 0.2 BUT I suspect the high pressure had something to do with it.

You missed his point, he meant what you have deduced.

I am confused by the stand at high water yesterday (Sun 20 Sept, 5m, Chi Harbour). What does anoyone think caused this? Surely the high pressure would have caused the tide to ebb sooner or is it that the large mass of water takes more time to change direction from flood to ebb?
 
Sailfree said:
No you missed the point others asked about barometric pressure as if it had a bearing on Kens OP.

The tidal range is affected by barometric pressure, tidal range has an effect on the strength of the tide flow. Ken was talking about difficulty in rowing due to currents.
I got it, you referred to it in an oblique way, I thought you had got it!

Just a note here;I normally make sure that I come in or go out with the tide behind me & I noticed that despite it being reported as a 5 meter tide the actual level was at least a foot lower than I have seen it before (up at the fareham end).

I'd agree. Up at Wicormarine, I have seen the water higher and lower - but never seen it stand so long!

A couple of boats racing (very slowly!) still managed to go aground near the cranes/barge pier, providing us with a bit of amusement as we worked away
 
I found the same on saturday, anchored off in River Yealm mouth just after slack low water. Did my normal thing of zooming the GPS in so i can keep an eye on any tracks we make. Started preparing the fish for lunch.

looked over and to my horror we were dragging

Reset!

3 drops later i managed to get a firm enough hold to keep her holding but i was watching the depth sounder over a course of half an hour and gained nearly 2 metres of water :O
