Tides for Swanage/Peveril Point tide race. 11 & 12 October 2008
These are my workings but could well be wrong so check them yourselves!
Tide phase - midway between neap/spring (check this too)
All times BST
Ebb begins HW Dover minus 30mins.

1002 - 0:30 = 0932 1232 1532
2222 - 0:30 = 2152 0052 (Mon) 0352 (Mon)
Saturday is an early start with mid ebb (strongest flow) about 1151.
Sunday looks more relaxed with mid ebb about 1232 and the peak at teatime, 1532.
The good thing about the early start is that we have plenty of daylight for the race and don't get overtaken by darkness.
Should we have a meeting to discuss the general idea and to start on specific issues?
