Reeves Fowkes

[chippysmith]

Really confuses me sometimes /forums/images/graemlins/confused.gif Leaving tomorrow evening, Using reeves fowkes for cts.. Now, Belfield states HW (sat) as 0540 (4.8) which is GMT +2 Reeds is 0425 (4.7) which is French satandard time. I believe this as to be used when plotting from the Reeves... is this correct?

Thanks in advance

You want the Cherbourg Tide Tables for 2006, which the Reeves-Fowkes Tables use as time/height reference.

They're found on the Adlard Coles website here:

Cherbourg Tides 2006

and you need to 'Click here to download Cherbourg Tide Tables 2006'.

If the inter-conversions between UTC/GMT/Zone+1/French Summer Time etc. confuse you, don't do an RYA course in the hope of clarification. It's not in the syllabus; those jumped-up dinghy sailors don't understand that stuff.

Excellent, have printed that pdf and will tuck it in the back.. Tides relate to so confusion over.

It's a shame they dont teach it because It works brilliantly, especially calculating tidal offsets for a cross channel

Thanks again

You\'re right, but there\'s a but!

It is a fantastically simple to use system, I've used it for nearly twenty years now. However, it doesn't really cover much outside the populated south coast areas. In the west of Ireland, or the Scottish Highlands, or most other regions, it's back to interpolation.

I assume the model becomes less accurate the further you are from Cherbourg.

The RYA are right to teach more widely applicable methods.

Also, it's interesting that you like it for plotting cross channel tidal vectors. Personally, I can't see it has much advantage over an Admiralty tidal atlas for that purpose.

To me, the real benefit of the Reeve Fowkes method is the almost instant read off of tidal heights. Of course, tidal software will give it to me even quicker, but come on, where's the romance and fun in that?
