Bruce:
You can still do a dip pole jibe with a babystay......just disconnect
the baby stay before the spinnaker is raised and connect it when it is
doused. You don't need the baby stay flying a chute.

Thanks everyone for your input! Based on what was said, I'll agree
that what we have is a symmetrical spinnaker. At this point, there is
no ring nor a track on the front of the mast onto which to mount a
slide car ring.
There is also a babystay to contend with, which presumably would not
allow me to do the dip-pole approach, but having never done it,
perhaps I'm not visualizing the concept properly.
At any rate, we're cruisers (though we love to cruise fast!), which
means that at least for now, we'll use the spinnaker as asymmetrical,
and figure it out from there. I have some friends that are due back
from a cruise, and I'm sure they have experience with both types, so
that will help me tremendously.
Thank again, everyone, this list is invaluable!

Most of what Josh said is correct. However, all symmetrical
spinnakers I have seen have the numbers on both sides of the
spinnaker, so you don't have to be concerned about which side is port
and which side is starboard.Before you buy any necessary gear for the
spinnaker, learn about end for end gybes and dip pole gybes. People
who do end for end gybes swear that they are easier than dip pole
gybes, and those who use dip pole, swear that they are easier than end
for end. I have done both, and I prefer dip pole. They are safer, as
you never have to disconnect the pole from the mast during a gybe.
Also the connection to the mast is stronger. (I once had the ring on
my mast track twist out of shape on a boat with which I did end for
end.) That's what caused me to switch to dip pole, and I never
regretted it. When I was getting new crew for my boat, none of them
had ever done dip pole gybes, but I trained them, and they are now
expert at it. If you're not going to race your boat, you can use the
spinnaker as though it were an A-sail, so you should learn about how
an A-sail is handled also. You didn't indicate what size boat you
have. With a smaller boat, end for end gybes are the way to go. At
thirty feet, you can go either way. At thirty-four feet and larger, I
recommend dip pole. Keep in mind, though, it's not the boat length
that makes one a better choice than the other. It's the size of the
spinnaker. My previous boat was an Ericson 2-30, with a tall mast.
The spinnaker was 1,000 square feet, and the boat was set up for dip
pole gybes

It sounds like a symmetrical spinnaker. The luff and leach are the
same length... In fact they are interchangeable depending on the
tack of the boat.
You'll need a spinnaker pole roughly equal to the "J" length (head
stay to the mast). The pole is set parallel/in line with the
boom, jaws facing up so that when they are opened the jaw can fall
away from the mast ring and the "guy" can fly up. The pole will
have 2 bridles, one on top, one on bottom. Both bridles will be
anchored are the pole ends and will have a ring fixed in the
center. There isn't much need to have the bridles tight so the
rings may ride 12 to 24 inches above/below the pole. The top
bridle creates a way to lift the pole with a rope that exists the
mast about halfway up and below impediments such as a radar. This
rope is called the topping tift and is used to hold the pole
horizontal. The bottom bridle is attached to a rope that attaches
to the foredeck directly below. This rope is usually lead aft
along the toe rail and cleated off. It is called thw down haul
and is used to prevent the outboard end of the pole from being
lifted up by the spinnaker and "flying away". The inboard end of
the pole attaches to a ring on a track mounted on the forward face
of the mast. Typically I try to raise the ring to about my
height, this lifts the inboard end of the pole - high but easy to
reach. The topping lift can then be used to lift and hold the rest
of the pole horizontal as mentioned above. Both jaws on the pole
should have release lines wich extend ~3/4 of the length and are
anchored near the opposite end. This allows the operator to open
either jaw from nearly any location along the pole.
The out board end of the pole gets the windward spinsheet which
until the next jibe will be called the "guy". The leeward
spinsheet is just call the sheet. Both of these lines are
typically run through turning blocks near the aft end of the toe
rail which keep the lines lead outside of the life lines and then
fairlead them inside to a secondary winch. Trimming the guy means
keeping the pole perpendicular to the wind. Trimming the sheet
means letting it out until the windward sail edge (pole side)
begins to curl - too much curl? - sheet in. Every time you jibe
you will sail dead down wind ease the guy so that the pole is
roughly at a 45° angle. The sheet should be roughly matched.
Standing infront of the mast facing forward the foredeck operator
will reach up to the mast ring, pull the jaw release for the jaw
in the ring. The pole is now supported by and free to pivot about
on the top and bottom bridles. What was the inboard jaw is now
pushed out towards what was the leeward side of the boat. The jaw
is opened and what was the sheet is hooked in the jaw. Next what
was the outboard end jaw is opened releasing what was the guy and
that jaw is hooked to the mast ring. The foredeck operator shouts
"MADE!" so that the helm can finish the maneuver by jibing the
mainsail and the crew can trim the spinnaker. The old guy is now
the sheet and the old sheet is now the guy. The "leach" and the
"luff" have also swapped.
Some setups include "twings" which are open cheak snatch blocks
placed at the widest part of the toe rail on each side of the
boat. This holds the guy down and helps prevent the pole from
flying in addition to the down haul. Early in the jibe (about the
same time that the helm is turning dead down wind) the guy is
released from the twing, again windward side = guy. After the
pole is "MADE!" the new guy will be inserted into its respective
twing on the new windward side.
Each sheet will probably need to be about twice the boat length.
This is an end for end jibe and its easier to show than to explain
and easier to explain than to master.
Oh, and the green stripe usually would indicate the starboard side
of the sail but that is just so that the front faces forward and
numbers can be read. Often sail makers will put red stripes on the
port side and a yellow stripe on the foot. This also help when
packing the sail in a traditional bag. Since you have a sock it
is less needed.

OK, seems like a dumb question. We spread out the cruising
spinnaker on our lawn today, having not put it up before on
our new (to us) C&C 37/40+/. It is in a spinnaker sock. The
sheets were in the bag, but not attached to the sail. It is
made by UK. Along one edge is a bright green strip. It seems
like that is the luff, rather than the leach, but I can't tell
for sure. There are no labels that I can see, nor an edge with
a cable or reinforced luff seemingly build in. Both sides
seem to be the same length. Do I have an asymmetrical
spinnaker, and if I do, is the green the leach or the luff?
New to spinnakers, so your help would be greatly appreciated,
