Reeds Almanac advice for Beaulieu River

At the weekend I got my new 2010 Channel Almanac out of its wrapper and, on the approach to Beaulieu River (in the Solent for those not local to the area) opened it to check the chartlet to remind me which beacon I was supposed to line up with Lepe House as a leading line.

Then, remembering the thread on here started a week or so back about favourite places to go on the south coast and comments about the absence of water at the River entrance at low water springs, I thought I would see what Reeds advises about the times when entry is/is not possible.

To my complete amazement, the Almanac says "Entrance possible LW+/- 2". Fortunately I knew that to be complete bo$$ocks, when precisely the opposite is true. It was HW -2 as I entered the river and, although it was springs, we had less than 1m below the keel at its shallowest (draft 2.1m).

On returning home I have checked back through old copies and it appears this error has been there in each of the 2008 and 2009 editions as well as the current one. (Yes, I know I should chuck them out, but I just can't bring myself to do it). You have to go back to 2007 to find the correct advice when there was a rather helpful box giving the key info about the river, starting with the advice: "Ent dangerous LW +/- 2."

How can the editors change an entry from one year to the next and turn something that was right into total misinformation? I would feel very sorry for someone new to the Solent who ran aground at the river entrance by merely following the advice in the Almanac.

Will I be writing to the editors to tell them about the error? Probably not. I wrote to them a year ago to advise of similar misinformation in the entry for Dielette (northern France) - yet again a problem with entry times. I didn't even get an acknowledgement from them, let alone confirmation that there was indeed an error and that it would be corrected.

Now, I still think that Reeds is an excellent product. I just wonder how many errors there are in there that have gone uncorrected for years. Will I find out to my cost at some point in the future when I place my trust in the Almanac somewhere I don't know as the Solent and discover more dodgy advice?
 
I've read similar entries ... and entrance possible at +/- HW or LW is meaningless - unless you know what draft they're talking about ... We draw 0.6m less than you - and have been in at LW neaps with little issue, friends of ours draw a couple of feet and (I think) would easily get in at LW springs ...
So - what are they referring to when they give entrance times??

I agree it is bo$$ocks, its OK to get in and out much closer to LW than that.

Depends on your draft, and tidal range, but also you have to line up quite accurately into the entrance. YOu only need to be a few metres off to one side to see shallower depths on the sounder.

Agreed that comments like possible/not possible at HW +/- or LW +/- are meaningless, but it would not be if they adopted some kind of default assumption (e.g. yachts 1.5m) or, better still (but I accept it would have space implications) if they actually said "bar approx [1m]* below chart datum, entry may not be possible LW +/- 2 for draft 1.5m. Check tides carefully".

* This is a bit of a guess, please don't take this as gospel.
 
I can't agree that it's meaningless. Surely this is just a heads up for the skipper to look at the chart and think about draft and rise of tide. I read it as entry possible from LW+2 to LW-2. If you're approaching above half tide don't worry about it, if below half tide then better do the tidal calcs properly.
Loads of water there three hours after high last Saturday but then I only draw 1.2m so I reckoned I'd just about touch at LW.

With a range of 4 or 5 meters 1/2 tide should be about 2m more water - but more water than what. Surely reeds have a standard from which they work?? someone must know!! Your 1.2 is another foot less draft than mine so as you say - less of a problem

That's the rough sum I did in my head on Saturday but there was much more water than I calculated. On reflection three hours after high is much deeper than three hours before in the Solent which makes Reeds' approach even less accurate.

I think due to limitted space in the Almanac it's just a reminder to have a closer look at the charts if you're deep draft, the tides well down, and/or the weather's dodgy.

In that case, surely a more generic form of wording would be appropriate - something like:

"Vessels may encounter difficulty entering near low water. Consult tide times and heights carefully."
 
They don't seem to be too fussed about a consistent approach for all ports so maybe the LW +/- 2 isn't a misprint.

At Carentan they used to print a graph of tidal height, draft, and time for entry (I haven't looked this year to see if it's still there). Ok things are rather more critical there than at Beaulieu, but I suspect they're just using whatever information they can get hold of from local sources.

I wonder if you have stumbled across one of the deliberate errors many publishers put into reference works in order to detect theft by other publishers? It has to be something which is likely to get copied, but also something which is unlikely to cause harm, which is surely the case for something as obvious as this?
 
Just checked Wiley Nautical Almanac (online) too ...

Access: Outside LW+/-2

Then in the narrative: Due to bar and shifting sands, entrance should only be attempted outside LW +/-2

Then they show a chart of the entrance with the transits and a little note on it "Not to be used for Navigation" ... er ... I thought Almanacs were supposed to be part of the skippers Navigation tools!
 
I read it as entry possible from LW+2 toLW-2.

I read it exactly the opposite way. If it were HW+/-2 then I would be read that as 2 hours either side of HW. So, to me, LW+/-2 means two hours either side of LW. After all that is clearly what they meant in 2007 with "ENT dangerous ..."

As an aside, even with my 2.1m draft I can get in at LW heaps if I am careful with the approach.
 
When you say you read it as entry possible from LW+2 to LW-2 were you being serious ?
Yes. From two hours after low water to two hours before the next low water. Makes sense to me. Surely nobody is going to avoid HW and wait for two hours before low to approach a shallow entrance!

Of course if you are approaching an unfamiliar entrance, it is always prudent to draw up ones own secondary ports calculations to establish tidal clearance. If the amount of water looks tight, then consideration must also be given to barometric pressure, with the current High, sea levels will be lower at all states of tide.

Unless there is a good margin, merely refering to any single source of information could be asking for trouble.
 
I'm with DJE on this one. I accept it seems a bit weird but would guess this is something to do with the double HW in the Solent. Elsewhere tidal heights are calculated from HW, in the Solent and surrounding areas they are calculated from LW. Would it not be the case then that entrance times are best mentioned in terms of LW rather than HW especially as there are 2 HW's.

Hey! Don't get me wrong. I've nothing against using LW as the reference point. But, what was wrong with something closer to to 2007 entry? Perhaps replacing "dangerous" with "only with care".
