I have taken on the organisation of this rally which was great fun last year. You will need to come up on the Friday as the tides are late that weekend and also to make the most of the day on Saturday as the buses start at 10 am.
The buses run every half hour and start on the quayside and the camaraderie on the wonderful old buses is fantastic. It is all free except for the optional route and pub guide which is £7 but which is partly offset by a 50 pence discount on the first round in each pub (if you can drink 14 pints then the guide is free!) We will have a small aperitif by FRITH at 1800 as I'm guessing most people will have had enough to drink by then and adjourn across the river to the Bargemans Rest where I have booked a table for 10~15 Seals at 7 pm. Please let me know early if you are interested so that I can get an idea of numbers for the pub.
HW Friday is at 1402 BST (Portsmouth) and as it is only three days after maximum spring tide, the height will be 4.8M - 0.6M = 4.2M. The harbour dries at 1.4Ms so at HW there should be 2.8M. There is apparently a double tide at or near HW Springs which exhibits as more of a stand so you should have at least 2M +/- 2 Hours of HW.
HW Sunday is 0300 BST (3.9M) and 1518 BST (3.9M) Times are Portsmouth and there is no difference for Newport and heights are adjusted for Newport.
I believe I have calculated the corrections properly but caveat emptor, please check yourselves.
