This is a bitch to understand as a pond / no tide sailor IE me.

 

BUT drawing out the situation on paper really helps to understand the discussion because when you are sitting on the water it is hard to realise what is happening to you when it is oblivious from the club house.

It`s also a situaion that I always fail to realise untill it`s to late when it`s happening & so it`s worth while to make time to look at the lay of the water & tide to see what you should expect before getting the boat out.

 

However this is an excellent discussion & is quite easy to follow & understand.

 

Thanks GRF.

Er...

This could develop into a full blown chapter.

I always maintain it does matter.

Take the lee bow early and only the weather bow on favorable shifts.


I also always used to suggest the length of the startline is very important
and how far down tide the favored end might be in relation to the time
duration of the beat.

Depending on those calculations, is how long you get to stay on the
favored tack, enhanced by how far down tide of the start line you position
yourself at the gun. Extreme circumstances can produce a one tack beat
when the wind has dropped for example and all the boats from the none
favored end sailing high and relatively fast lay the mark bang on whereas
those at the favored end find themselves having to free off further and
further going slower and slower with the same effect of being the wrong
end of a 'knock'. Extreme, but it makes the point and has happened to me
over the years enough times to cover for.

Yes you should consider the tide as a conveyor belt and everyones
position relative to each other remains equal, but factor in time and
reduced wind and some can find themselves more 'equal' than others in
relation to fixed mark positions has often been my experience as has
travelling faster earlier rather than having to pay catch up later..

So far you've said you'd do the lee-bow tack late...

starboard having understood enough for the tide to lift me the last bit.


and early...

Can you clarify whether you would do the lee-bow tack early or late or both?
What if there's a favourable shift right at the start?

What's a "final run"? 10 yards? 100 yards? It's worth pointing out that everyone in the race will do a "final run" of some duration on starboard if it's a port rounding.

I still maintain that what you're advocating when you say "...only the weather bow on favorable shifts" is nothing more than "play the shifts", a strategy with which I wholeheartedly agree.

Personally I'd always go for the lee bow tack first, wether it was left or
right for the reasons I made earlier (you never know how things will pan
out later in the beat). (Even more important if the tide is going right to
left for example simply because with the majority of the fleet on
starboard, manage to get out the back door right early, nine times out of
ten you'll nail them simply because the starboard nature of the majority
forces them way down tide and they over stand on the way back.)

I might well ignore it, depending on my calculations regarding the start
line length, course length and time duration and how much left to right
tide I'd be expecting. A favorable shift (lift at the start)could see you
massively over standing if you were already at the pin end.. Alternatively
a genuine favorable shift which of course I take to mean a massive header
shortly after the start with me down the Port End I wouldn't obviously
ignore and would probably knock the tide off the lee bow anyway, that I
couldn't ignore.

The last 25 % of the course give or take. How can you totally qualify it?
For that course my strategy would have been to try for..
First 25 % Left, mid 50% middle and left but trending ever right, and final
approach right, and short of the lay line getting lifted by the tide.

But of course events can occurr, but overiding everything the
fundamental rule is always Take the tack that's taking you closest the
mark
and if the tide is assisting that tack all the better.

I still think you're all (including the DSM guy) saying pretty much the same thing. Go left, use the shifts and finally come into the mark on starboard like we all do unless we're feeling suicidal or the fleet is thin.

Still, thanks, it's always good for us creek-dwellers to get our heads out of our banjos once in a while.
