Could this spinnaker trim be improved?


Not much!


It appears that a gust has hit the sail high up, and pushed out the top of
the sail, which has resulted in the bottom half getting pinched.

The boats behind seem to have better spinnaker shape, and yet they are
trailing. As this is a one design race, I would assume that the photo must
have been taken at an unfortunate time. There is no way, in a one design
fleet, that a boat with such a badly trimmed spinnaker could be so far in
the lead.


Can you offer a better explanation?



Regards


Donal

Nope, different beast.
Star cut is all radials, no crosscut section like the radial head or
triradial.

Star cut is a reaching and heavy air spinnaker.


I'm referring to Doug's talk about cross cut spinnakers. Try to keep up Oz!

Actually Oz1 just seconded pretty much the same thing I said about star
cuts. Have you been studying reading comprehension under Jax again?

I'm keeping up quite well thanks.
Here is what Doug said
"Many Lightnings do use star cuts, they are flat reaching or heavy air
'chutes. For running & light air, the old fashioned cross cut is
better.
It can be cut with deeper shape, bigger shoulders, and it's lighter
because there is less seam per unit area."

Just to clarify, I believe that when he talks about a running
spinnaker that is "old fashioned cross cut" he would be refering to a
radial headed x cut as it most common.

So you've never seen a cross cut spinnaker?

Where did I say that?
But the answer would be No, not that I recall.


Well Doug raised the term cross cut and I wondered if he was confused
(giving him the benifit of the doubt you see) and really talking about
radial heads. Cross cut spinnakers largely disappeared years ago but
check this out:

On bigger spinnakers, yes. The Lightning is 300 Sq Ft, and it's cross
cut all the way up. I think the Etchells is something like 475 (?) and
benefits from radial panels. They put radial heads on Lightning runners
for a while, back in the early 1990s or so, but decided it wasn't worth it.

BTW there is an Etchells fleet in Oriental NC and some of them went to
one of the big championships... now they're swanking it up with bow
numbers ;)

Spinnakers... Navvie really doesn't know

Really? That must be why the current North and Sobstad runners on
Lightnings (and a few other one designs I believe) are all cross cut.

If you look at the panels on the spinnaker you've been criticizing for a
week, you'd see plainly that it is cross cut.

I said 'largely' and even gave a URL (read the post) to all cross cut
spins Doug. So what are you trying to get at, are you saying that radial
cuts are not the most common running spinnaker by far?

Yep, I know what tey look like.
Just can't recall ever seeing not using one except maybe waaaaaay back
in '60/61 in Manly Juniors. They may still use x cut spinnakers which
also double as handkerchiefs.


Well your experience tallies with mine but that's not Doug's opinion and
he's getting quite stroppy about it.
