THE HISTORY OF THE SPINNAKER SLEEVE
The first spinnaker catching device was invented in Germany, about 35 years ago. It was known then under the name of the "Blue Max". It was a very simple cloth tube, with a rigid opening in its base and a closed loop line half internal to the tube to control its up and down. Nobody really noticed it then, since sailing and spinnaker flying were not very popular at the time.
However, one person recognized the need for such a device. Eric Tabarly, the French single handed ace, asked his trusted sail maker Victor Tonnerre to make him one for the 1976 OSTAR (single handed transatlantic race) to allow him to sail his "Pen Duick 6" (Whitbread 72' ketch). He won the race and, for the general public, the spinnaker sleeve was discovered. Soon after, every sailmaker in France was building their own version.
In the US, Brad Mack of then "Mack-Shaw sailmakers" in Fort Lauderdale and "Cruising Systems" of Marblehead, MA with their "Sally", should be credited with the first serious attempt at the modern spinnaker sleeve.
The early spinnaker dousing devices were very similar to each other. They were made out of spinnaker or bag cloth which would cling to the spinnaker when wet, the lines (always too small), burned the hands and would foul and wrap around the spinnaker. In short, they were unreliable and unsafe even when handled by experienced crew.
ORIGINAL INVENTOR OF THE SPINNAKER SLEEVE FOUND
While exhibiting in the Grand Pavois in La
Rochelle, France, I had the great pleasure of
meeting the original inventor of the spinnaker
handling device from which all the spinnaker
sleeves, snuffers, socks and chaussettes de spi
are derived.
Mr.
Bengt Ebbeson, from Sweden (now a Floridian like
me), who while awaiting delivery of his brand
new Amel Super Maramu, was strolling the isles
of the Grand Pavois. He saw the small demo ATN
sleeve hanging in my booth and proceeded to tell
me that he was the holder of the American patent
since the 1960s. I was delighted to meet the man
and finally hear the real story about it.
I
knew that Eric Tabarly, the very well known
French solo sailor, had noticed it while sailing
in the North Sea in 1965, and that he conceived
his own in 1968 for the single handed
transatlantic Ostar, helping him win it on his
73' ketch "Pen Duick 6". For the French public,
Eric Tararly had invented the "chaussette de spi"
(spinnaker sock). (Eric Tabarly never claimed
this.) I knew this because Eric Tabarly mentions
seeing a spinnaker handling device in his book
"de Pen Duick a Pen Duick" in a boat show in
Hamburg. I remembered a name like "blue Max".
In
fact, it was called the Blue Jack: it was a
joke, a pun on the very well known Scandinavian
condom "Black Jack". Speaking of this, my
ATN spinnaker sleeves are often called spinnaker
condoms by lower class sailors (mostly kiwis,
aussies, pomies and of course my fellow citizen
Americans)
Since then, Mr. Bengt Ebbeson went onto much
bigger things. He is now the R&D director of
Dometic (Sears).. |

"There is no question, the difference is worth it" -- Practical Sailor Magazine
"Ten years ago we first tried an ATN spinnaker sock on our 67-foot Sundeer. The result was extraordinary. The ATN system worked well enough for two of us to use our spinnaker more often than not on downwind passages. Today my wife Linda and I still use the ATN sock on our 78-foot Beowulf, and recommend it to all our clients. There simply is not a better way to handle a spinnaker."
-- Steve Dashew / Sundeer Yachts
"Dear Sir, I have used extensively your spinnaker snuffer and find that it has been a tremendous help with shorthanded sailing. My wife stopped being afraid of the spinnaker and actually now enjoys flying it." -- from Paris Genalis, Annapolis MD

"Anybody can get a sail up--
It takes a sailor to get it down"
|
That statement is particularly true regarding the spinnaker. The problem is not to hoist the sail but to get it back on the boat. That's when the spinnaker sleeve makes the average sailboat owner a great sailor. Without any help, he makes that very powerful and expensive sail disappear with a minimum of fuss and trauma. And the sail is ready to be hoisted again immediately, no more packing!
While it would seem that a spinnaker sleeve is a simple sailing tool, and that any one with a sewing machine could design and fabricate one, when dealing with large sails, the problems increase rapidly in complexity and cost. It is very plausible to get hurt or to inflict great injury to others, and to one's wallet, if the system used is inadequate. But there is no need to rub it in, especially at sea: it has to work and be reliable.

| Problems Solved by the ATN Spinnaker Sleeve |
- The main problem to solve was the mixing of the control lines and the sail.
A separate channel (which contains the control line) is sewn alongside the main sleeve which contains the spinnaker. The spinnaker and the control line are completely separated . The separate channel (side sleeve) is made of a different colored cloth than the main sleeve which shows the eventual twists of the sleeve prior of hoisting it. There will often be some twists in the sleeved spinnaker as it comes out of the bag, especially after long periods of storing and moving it around the sail locker. Needless to say, those twists are to be removed before hoisting the sleeve.
- Another problem to address was the opening, the mouth of the sleeve.
It had to be rigid to remain open when pulled against the sail, slippery to enable it to slide over the sail without chafing it, light (weight aloft should always be avoided) and sturdy enough not to break in the bag when stepped on or stored. Fiber glass was, from the beginning, the material of choice by its versatility and ease of manufacturing. While the round shape seems obvious, the oval shape is more spinnaker friendly for it doesn't have the tendency to rotate around the sail as it is guided by the spinnaker leeches and it is easier to slide through the hatch when storing below deck. We make them out of Kevlar and glass which, while expensive, offers a good combination of strength and lightness.
The control line is a closed loop, made of 2 different lines. One side is to hoist the sleeve. It must not kink and it should be small enough to travel in the side sleeve and through the top turning block. The other side must be much heavier as it is handled by the operator to douse the sail. It also must not kink as well as be long enough to be lead through a snatch-block, as Steve Dashew suggests in his very thorough "Offshore Cruising Encyclopedia", in the fore deck and then to a cleat or a winch on bigger boats.
- The cloth problem came from the fact that spinnaker or bag cloth doesn't breathe and might bleed.
The cloth that is milled especially for ATN is a "tricot", a mesh like material which is light, strong, and doesn't retain water. The sail can dry when in the sleeve and it will not cling to the sail when hoisting the sleeve, even after long period of wet storing.
- Finally, the spinnaker is fastened inside the spinnaker sleeve with a swivel shackle to allow gibing.
The hoisted spinnaker sleeve must always remain in the same position at the mast head, on top of the flying spinnaker, while allowing the spinnaker to rotate under itself. This also gives more flexibility when loading the sail.

- High-tech, ultra-light Kevlar Hoop matches shape of the spinnaker and will not warp under load
- Single control line led through separate sleeve eliminates fouling
- Contrasting visual reference stripe
- Wire pennant with swivel at head of spinnaker prevents sleeve from affecting sail shape by allowing the sleeve to accumulate on the pennant
- Mesh construction allows sail to breathe, so that sails dry quicker, even while stored
