It is considered to be on the same tack as it was before going
head to wind.
Correct of course.
I meant to exclude you from answering in the interest of furthering
the education of this motely rabble.

Here's a tricky one... if a vessel is sailing along close
hauled, and the wind shifts 90 degrees, forcing her sails across
while the vessel continues on a straight course, has she
'tacked'?

Ahhh, one must ask is movement of the helm required for it to be
considered a tack.

I welcome you to crackerbox palace,We've been expecting you.



Well, the wind is coming over the other rail, so the vessel
is now on a different tack; ergo the vessel has tacked.

A more accurate way to say it is 'the vessel has been tacked.' Happens
all the time on smaller lakes with flukey winds. Sometimes two boats
going bow to bow will be on the same tack.... more of a probelm if
they're both on starboard...

Work this out: four boats racing (one FLying Tadpole II) in two
pairs on gently converging courses (roughly EbyS and EbyN), pairs
about 70m apart, FTII then another on port tack, other two on
starboard tack, meeting another boat coming W, also on starboard
tack. All five have the wind forward. FT2 is hard on a cliff with
no upwind manoeuvring room. WHat happens next? (Clayton Narrows
on the lower Murray, 1994 or 95).

Hail for room to tack. The usual call is "Water!" which I always answer
with "Beer!" but give room anyway.

Don't you find the wind diminished in strength and somewhat flukey hard
under a cliff? Or did it not matter 'cuz you could keep way on with full
topsails?

The strange situation arises because of the flukiness. What
litlle wind there was was sort-of southerly (doldrums between the
land-breeze northeasterly and the southwesterlyto southeasterly
sea breeze). Clayton Narrows on the lower Murray is about 1.5 n
mi southeasterly, and about 300m wide with low hillocky rises one
side and about 1km of limestaone cliff 15m on the other. If the
wind is southerly and light, with an easterly component, one can
get a nice back eddy off the cliff, which is why FT2 and
companion were where they were. OTOH one can benefit from wind
funnels on the other side, which is why the other pair were where
they were. What actually happend was that the two pairs proceeded
on and eventually strung out, so no need to cry for water. But
the poor oncoming boat hit the local eddies the other four were
sailing on, and was taken aback. We all passed her while she was
undoing the tangle.

The cliff and related eddies of the lower Murray R are why I
always relax as Lady Kate comes out onto the relatively open
waters of the Murray Lakes.
