Hat off to you both. I guess we've all got a preference for our own piece of water.
I doubt the gusts on the south coast are quite the same thing but we do get them with an offshore wind. They quite often have their own individual smell. Imagine a seafront with Victorian terraces, there are gaps at road junctions. I believe the London road gust in Hastings smells of Kebabs. The Warrior square gust has the distinct odour of cannabis |

Haha yes - used to happen a lot at South Windermere.
Not so much since I moved to Ullswater where the wind is "steady" |

I experienced similar on Bala, two Div 1 Windsurfers, 30 yards apart, sailing exactly the same course upwind on opposite tacks.

When I win the lottery I am going to fly 100s of drones over the lake with sensors and analyse the wind for a few weeks.
Or perhaps move to some tropical island..... Obviously somewhere without tides Edited by tink - 18 Nov 19 at 7:15pm |

Since they pump their way up wind, when it's calm, it's their choice which tack to be on? Either that or one was 'leebowing' with some sort of divide by zero (tide) error? Makes as much sense as anything else on that subject....

In terms of improving accuracy of tidal yardstick, I'd have thought a combination of varying tidal venues will be more accurate than having non tidal venues still in there. For inland venues, removal of tides will also be more accurate, even looking at Rutland and Shearwater, judging by the comments on this thread.

Of course tidal gates can allow fast boats to get past points where slow boats can simply not get past!
