Guys

I feel a bit silly asking but if you don't ask...............

The PO left me a lovely set of sails:
No 1, No 2, No 3, spare main, 0.75 oz spin, 1.5 oz spin, a spare light spin and another sail in a bag marked ASSY.

Now I've flown the 0.75 but not the ASSY and I'm keen to do so.
I've had it out of the bag once or twice but today I decided to measure it. Well I got a luff and leach of exactly the same size 38'. I would just assumed that it is another spin but it was clearly labelled HEAD, TACK and CLEW unlike the other spin.

So what have I got, a ASSY or another spin and how do I tell?

Cheers

it's an asymmetric spinnaker and the reason it is marked as you describe is that it shape cut in it similar to your main and you can only fly it one way, hence the markings.

For further clarification, have a look at an 18' skiff under kite and you will see that draught is forward of the midpoint.

You don't need a snuffer, just something else to go wrong. I fly a cruising chute [assy] singlehanded OK.

I am just a meer mortal with the sailing skills of a dyslexic moose.

You on the other hand possess skills that make Slocomb, Chitchester and Knox-Johnston resemble kiddies playing on the pond in their Opti's.

I have thoguht about sockless but I honestly hope it will be easier especially for short handed racing. Hopefully it will save me hving to repack.

I need all the help I can get.

Final got arounbd to hoisting the sail.
Picked up a sock for it too.

Was out on the water from Brighton about 745 this morning to try and beat the breeze.
Approx. 10knts.
Sailed out past the beacon and then came about.
Put the Jib away and rigged for the Assy.

Hoist:
Mucking about trying to get the tack on is a bit of a problem but doable due to its position on the anchor roller.
Hook up the sock and hoist.
I ran the halyard around a winch and led it forward so I could hoist the sock from the deck.
Worked okay but had to 'sweat' the mast and then gather the slack from the winch as too much friction just to use the winch.
I had tied the bottom of the sock off on the life lines and left a lot of slack in the sheets.
Connected sheets and then raised sock – this worked okay except for a small tangle inside the sock.
Once sock was raised back to the cockpit and trim.

Everything seemed to work okay but it just felt like it took too long.

Sailing:
I was a little disappointed in the performance.
I did not see an increase in speed that I was after.
The luff kept curling even when I attempted different angles.
Meant to take a photo but couldn't get the sail into the frame.
I also had to go clear the lazy sheet which went under the bow and cleaned our hull!

Gybe:
The method of gybing I used was to centre the main so I could concentrate on the Assy.
When the boat came through the wind release the sheets and let the Assy go forward and then use the old lazy sheet (now the active sheet) and trim.
The problems I had were that the sheets dragged in the water and I could not get the Assy to float fwd.
I eventually managed it but not without having to go fwd and manhandle the sheets from the water. Maybe 12mm sheets are too heavy?
During this process the new lazy sheet went under the bow again and this time got hooked on the rudder.

Dowsing:
The line I rigged to blow the tack did not work. The shackle became reorientated 180 and therefore not a straight pull.
The Assy blew back onto the spreaders making it difficult to get the sock down.
There is a design fault on the sock which caused the sock not to be released in its entirety.
After a bit of pulling and prodding I finally got the sock down and then released the halyard from the cockpit and stuffed the Assy down into the cabin.


Observations:
When the sock worked it worked well.
There is a fault at the head of the sock and as this sock has all lines routed externally to the sock (most have a separate pocket) it is messy.
I'm not sure that the sock is worth the effort.
I need to check if the sheets are too heavy.

The most important thing was that:

I got to see dolphins!

What a great way to start a day.

Why don't you fold the presumed assy in half and see if it is symmetrical
Ie. pull the sail out flat and fold it so the corners marked tack and clew are together...work ur way up the sail pinching the edges together and making sure the fabric on the top and bottom is the same tension as you work up the sail to the head. A sym spinnaker generally has a seam down the centre. If you can pull the top and bottom layers out to be the same shape it is symmetrical.... If not its assymetric as marked on your sail bag.... But you can never be to sure!
