It looks like an ancient radial head symmetrical spinnaker, monetarily worthless, fun factor priceless. Just play with it some day and you will justify keeping it around.

...but find somebody who has some idea of how to rig and fly a spinnaker, have him go out with you, and reward him or her with some very good beer. A spinnaker can get you into trouble if you have no idea how to handle it.

If you want to sell it and you have a standard rig, let me know. I need a backup spinnaker. But I hate the colors. Rainbow is allright but a black bottom?

It is a symmetrical radial head spinnaker. If you have a pole and the rigging it is a ton of fun in around 10 - 12 knots of wind.

See my signature photo.

Ok about the colors , but (and I have no problem with this) you know that all rainbow colors with no other color signifies an alternative lifestyle

As a decal on the bumper of a car for sure, but sailors tend more toward the philosophical. I'd say that the rainbow on your kite was meant to signify something more like, we can see (perceive) just a very narrow part of the electromagnetic spectrum and, as Saint Exupery said, what is essential is invisible to the eyes.
Don't go fly a kite without having someone that gets it, especially if conditions are getting up there. It might be good to have the membership post their most "interesting" experiences flying spinnakers.

Ok Guys, I'm curious.. what aspects of that photo indicates it's a symetrical rather than an asymetrical cruising chute?
I know that often sym chutes have colored 'clews' to help manage the sail, and crusing chutes have a tack and clew, but I don't see any colored clews(pun).

unless its gonna get me a couple of hundred bucks, I dont see the point of selling it, I would rather keep it as a nice sail inventory if I ever sell the boat
and I was just messing around about the rainbow colors,,
I know that has no value with sailing

Its clear from the picture that both sides of the sail are equal length and equal shape. Thus symmetrical spinnaker. An Asym has a tack and a clew and the clew is cut much higher.

Quilombo, if the sail was 0.75 OZ and you have a standard rig, me paying you $200 + shipping is quite reasonable. Do you have a turtle bag with it?

I recently got a used symetrical spinaker. It's 40'x40'x22'
and so has an area of 440 square feet. Do I need a
spinaker pole for this or is there a way to use it on
my boat without one? I have a SRSK. Also, how would I
attach the pole to the mast? Is there some kind of kit
I could buy? I currently have a 130% roller furling Genoa.
Would I need to take that off in order to use the existing
halyard to hoist the spinaker or is there a way to add a
halyard to the masthead? Wondering in Tacoma...

Yay! Someone said post most interesting spinnaker experiences, I don't have to be told twice! I wanted to tell this one because I just talked to my old friend the other day and the first thing he said to me was "Remember when we flew your spinnaker in 40kts of wind? Why didn't the mast break? The mast should have broken!"

I went to the marina to make sure everything was snug because a storm was coming in, it was blowing 40+. I was below decks and turned around and there was my friend, his head hanging down into the campanionway, he was laying on the cabin top looking in. This guy is a sailmaker and had helped me design a removable bowsprit from which I could fly an asymmetrical spinnaker, of his design. The set up was new and only tried in light air so far.

As we were leaving the marina downwind, I was at the helm and taking care of things in the cockpit, he was rigging the spinnaker. He was hoisting it as we were clearing the No Wake bouys. The wind was so loud I could not hear what he was yelling, but last I looked up he was about to cleat off the halyard, so when he yelled I thought he was saying CLEAT THE LEEWARD SHEET, so I grabbed the leward spin sheet and cleated it. I looked up then and saw my buddy nearly at the spreaders and gaining speed. I yanked the sheet loose and he plummeted to the deck. His hands were badly blistered, but he was running on adrenaline and hoisted again. This time he got it up and cleated it and we got it under control. We sailed it off wind for several miles and the boat would almost plane; it would lift up and surge forward, then drop down again.

We didn't break the mast, but the asymmetrial sprit pole bent eventually. The next pole I installed was much stronger and I use it to this day.

My buddy was not able to work in the pits at his business or even cut cloth for several days after that. I felt bad about burning his hands, but he laughed it off and said it was crazy to sail in those conditions and it was his own fault for suggesting it.

One last note, the wind had blown the water into such square waves that we couldn't use the motor to go back up wind, everytime the boat would crest a wave the screw would come out of the water and the engine would rev to a screaming pitch. We sailed back up under power of storm jib.

About 30 years ago when I was much younger and MUCH lighter I was on my boss' (at the time) C27 while we were practicing for race. The winds were in the upper teens with gusts into the mid 20's. I only weighed about 150 lbs at the time. We decided to practice hoisting the spinnaker and I had the same experience as Stardog's friend. When the chute opened it yanked me about five feet off the deck before I knew what happened. Luckily one of the crew members was nearby and grabbed the halyard and got it around the winch while I hung on for dear life.

Once we got the chute set the boat was out of control. It was slapping the boom in the water on both sides of the boat. It didn't take long for us to decide to get the thing down. We ended up with most of the sail in the water around the keel. We finally got it back on board without any major damage and just went back to the dock and called it a day.

40 x 40 x 22 is way too big and can not be used on a C-25 SR.

30 high and 16 wide is the right size.

The spinnaker can not be allowed to droop below the bow pulpit.

40 feet would put it in the water.

Hmmm...I'm getting conflicting information here.
According to this site http://www.mauriprosailing.com/sailboat-rig-dimensions.htm this sail would actually be a little small.
For a C25 the formula is: I=29.0, J=10.5, P=24.7, E=9.6 which, by my
crappy math skills gives a recommended sail area of 548.1 Sq. Feet
(1.8 x J x I) The area of my spinaker is only 440 Sq. Feet. Am I figuring this incorrectly?

This might be helpful, it's from the class association rules:

e. Spinnakers
(1) Luff - The length of the luffs shall be taken as the distance between the highest point of the sail and the foot measured around the edge of the luff. The dimension shall not exceed: Tall Rig - 31' 1"; Standard Rig - 29' 3 1/2".
(2) Girth - The maximum shall be measured across the widest point of the sail between points equidistant from the head. The dimension shall not exceed 18' 10 3/4".

I think measuring the square footage takes a bit more math, because of the curvature of the foot and leeches (luff/leech).

Oh well, I ended up giving the damn thing to a friend
with a 36' Hunter. I've lived without a spinnaker all
these years, no big deal.

I went out a few years ago on a good friend's Starwind 27 with another very good sailor/racer. We beat to the end of the lake, gybed and popped the chute (in 20+ knots!). We ran off the wind and it was virtually a beam reach - suddenly the wind went forward and blew the chute back through the foretriangle. Before I could react (they put me on the helm as I'd never flown a chute) the rudder was out of the water and we were standing on the sides of the cockpit lockers! After a few words and a heated dicussion, the spin halyard was blown, the rudder went back in the water, and turning DDW we retrieved the shrimping chute.
I do not reget not having a chute on Canyon Lake - I watch so many struggling in our constantly shifting winds (right Frank!)

Hello Folks,

I thought I’d add to the Spinnaker thread.

The spinnaker is said to have derived its name from the fact that an early version of the sail was first carried by the British yacht, Sphinx. It is said that rival crews called the sail a Sphinxer and sometimes referred to it as Sphinx’s Acre. Those names soon evolved into our present term for the sail

I bought this spinnaker from Quilombo. Now that I have it, it is a symmetrical spinnaker, but designed to be flown poleless (there is a bronze hank down by the tack and a pennant line for tacking it down.

It is not an asym. It can be flown on the pole.

I can't tell if it is 0.75 oz or 0.5 oz, feels the same as my 0.5 oz.

It is about 3/4 the size of my 0.5 oz spinnaker in my signature photos.

As far as I can tell it is in 100% perfect like new condition. I doubt its been flown more than twice (and once was the day I got it).

Sounds like you made a good purchase, it should be a good sail for heavy air down wind.

Looking for an asym for my C-25 Tall Rig....

class association rules:

e. Spinnakers
(1) Luff - The length of the luffs shall be taken as the distance between the highest point of the sail and the foot measured around the edge of the luff. The dimension shall not exceed: Tall Rig - 31' 1".
(2) Girth - The maximum shall be measured across the widest point of the sail between points equidistant from the head. The dimension shall not exceed 18' 10 3/4".

Do these measurements apply to an asym or spinnaker?

Thanks.

Since the plural of luff is used in the class rules, and probably written before asym's were popular, I would bet that it is referring to a symetrical spinnaker. Since the luff of an asym has to run from the masthead to the bow, I suspect that an asym for a TR C-25 should also have a luff no longer than 31'1"

Music Man, as to the halyard question, you will need a separate spinnaker halyard. It needs to be attached to the masthead in front of the forestay with a swivel block. There are 2 pins on the front of the masthead. If your forestay is attached to the front pin, it will need to be moved to the second pin in order to free up the front pin for the spin halyard swivel block.
