Why on earth does the tide make a difference? If you can go into point mode and gain a lee bow position on a boat to windward, how does the tide have any affect on this? Why could you not do the same with the tide from astern, or no tide at all? Or does point mode cease to exist as soon as you cross the coast and start sailing on ponds?

Still talking about something different... Carry on with the stuff about tactical options in tide though: fascinating and something I know Edited by JimC - 17 Oct 11 at 2:54pm |

I've just thought of a definite scenario when "pinching' in a tidal lee bow situation will be beneficial.
If there are two boats about even on the same tack, both in a tidal lee bow situation, then if the leeward of the two, pinches and establishes a lee bow overlap, i.e. gets his nose ahead of the windward boat but points high enough to establish a 'lee bow' header by distortion of the flow over the windward boats jib or main if its a single hander, then it will gain an advantage over that boat. No question, no doubt. Another example of Lee Bow and it's application at work. So now David Perry where is he now? Edited by G.R.F. - 17 Oct 11 at 12:47pm |

Thank you for that. I've been focussing on the boat on boat 'pinching' effect as the other two, (which I presume are the bigger picture tidal effect which relies on boat separation, and the wind effect caused by a boat which is very close to leeward ) are well documented and understood and are not in any way controversional. Ian btw In terms of the big picture tidal tactics grf is now focussing on, I can easily imagine where a windward bow effect could also be beneficial, when trying to soak down to a mark in light airs for instance. BUt it always depends on getting enough separation from the oposition to be in a different tidal effect..

Bert ... if you really want to understand then buy a book from a bloke who has won loads of championships and has coached at the highest levels ... http://www.amazon.co.uk/RYA-Tactics-Mark-Rushall/dp/1905104219 .... but GRPs etchings would no doubt be good for a laugh. |

I for one look forward the "drawings and try and remember all the tactical scenarios I used to illustrate and what to do in various circumstances to even the odds in your favour, but it won't get done overnight."
& thank you GRF if you can do for me / us -- no piss take I would geninely like to understand this better.
