How do we work out slack water at/around portland bill?

 

With most areas, slack water comes at either high or low water. But because of the bill sticking out so far off shore, it disrupts the natural tidal flow.

Kam,

 

You need an Almanac of the area - the Bill is unique in that as you correctly state it sticks out so far and you have two converging tide flows from each side.

 

The Almanac will show you the tide flow, direction and strength - if you apply this to the tides in the harbour you should get somewhere handy - however.....

 

I have tried many times and now as long as I have an idea I just go with the flow - last year whilst drifting for bass, we were drifting at 5 knots whilst less than 100 yards away in an eddy our buddy boat was stationary!!

 

The local's and skippers will have it sussed and may be able to help - but the almanac is your best bet.

Kam, there is a download available, which shows the tidestream at intervals, giving the flow in diagram format, with strength shown in long and shorter lines. Most charter skippers hjave one of these in the wheel house, to keep abreast of the tide, as it is very specific in the portland area. I'll try and blag one for you and laminate it for you. I'll see Colin Penny this Friday, and will grab one.
