New Owners and Boats on the Move

It has been several quiet years on the owners website since the last post in 2012 and 16 years since the first truckload of boats were delivered to Ohio.  2017 has been a year of resurgence as many of the boats are changing hands to new owners eager to learn and catch up maintenance items for these new-to-them boats.  Parts are available from the factory, and past owners can point you in the direction of successful replacements for tramps, sails and running rigging.  The hulls, beams and masts are bullet proof and will easily last another 16 years.  The boat, with its skeg design, is a great choice for shallow and weedy waters.  The spinnaker rig allows you to learn just like the bigger performance cats at a fraction of the purchase and maintenance costs.

The Yahoo group at Mystere Owners Yahoo Group remains your best source for owner support.  Several original owners are active and even past owners will jump in with assistance.  Thanks to Mike F., Dave and Karen for their continued advice to new owners.  The group still has 56 active members.    See www.mysterecomposites.com  or email e-mail   parts@mysterecomposites.com to contact the factory.

Many of the common rigging questions are covered on this site under rigging… https://mystereowners.wordpress.com/category/rigging/

Congratulations to all new owners, and enjoy the sail!

Mystere back in business

Good news for all 4.3 owners!  Mystere is back in business with the original owner and his son making boats again (as well as other fiberglass products); here is the website address:


You can order parts from this e-mail address:


We will get together for a one day regatta (annual Jolly Roger Sailing Club’s Cat Tail regatta) in Toledo the first Saturday in June. We will have practice the day before and plenty of BBQ and beer and socializing. There will be plenty of sharing of all things Mystere 4.3 including equipment, rigging, and technique.

Contact Mike Fahle or send a note to the mystere yahoo list for more discussion.

Mystere 4.3 Class is 10!!! Class site moves on…

Can you all believe it has been 10 full years since this journey began. January 2001, Mike Fahle called a few of us. Shortly thereafter I created a web site so that we could share photos, information, and status of delivery. The word spread and we bought 30 boats, sight unseen! On Friday April 20, 2001, 30 boats were unloaded and assembled at Park McRitchie’s warehouse in Port Clinton, Ohio.  Jamie Diamond and Dave Fort lead the creation of class rules supporting an open sail plan.  Another round was delivered in 2002 for the first “nationals” at Alum Creek. It has been a great time and most of the boats are still racing strong and are well cared for. It remains probably the strongest class in Ohio.

After 10 years of maintaining a hand built web site for the Mystere 4.3 class, I think it is time to move on to current technology. I have moved most of the content from the previous site to this implementation. This will allow the class to have multiple authorized editors, and hopefully will contribute to more active class news and discussion. The new implementation will be using WordPress in their cloud instance. WordPress is the most popular blogging software. It is much more suited to the kind of communication needed to support a sailing class than a hand built web site. This will change also allows me to shut down the last hosted site on my home server. I can power down that beast and the lights will get a little brighter in my house. The most recent releases of search engines favor known blogging and social software like WordPress in their rankings. This move will provide continued high ranking for the Mystere web presence.

I will leave both sites running for a short period of review by the class members. After which, I will shut down the old web presence and move the main mystere.org domain name to point at this site. Please comment on this post for any issues you may discover.

To see the old site, go to http://mystereowners.org/Mystere

To another great 10 years for the Mystere 4.3 Owners Association!!!

Mystere 4.3 Specifications

Specification Comparison with Similar Sized Catamarans

– 14 foot fiberglass hulls with skegs trimmed with protective aluminum strips
– Taller bronze anodized aluminum mast and larger mainsail of European “Sonic” model Mylar mainsail with fiberglass battens and sail numbers, Harken’s new “Black Magic” H 2647 and H2604 Carbo Air Blocks to make a 6:1 system, 4/1 downhaul with cleat on the mast, and a traveler
– Dacron jib with Harken H 362 jib blocks with cleats
– Nylon spinnaker with Ronstan RF 42100 Smart Ratchet spinnaker blocks
– One set of trapeze wires (one trapeze each side of boat)
– Bronze anodized aluminum beams with gray trampoline

OPTIONAL (strongly encouraged)
– Fiberglass snuffer spinnaker launch/retrieval system (ready to sail)


HULLS – The hulls weigh 60# each, so handling the boat with the mast down should be really easy compared to anything else, especially for double
stacking. The skegs have an aluminum strip on the bottom to help protect the gelcoat finish from wear and tear. The hulls are “sleeker” than those on the Hobie Wave and will be more easily driven. The designed load limit is 300#.

BLOCKS – The mainsheet system features Harken’s newest style blocks. They are open in the middle to save weight, hence the name air blocks. They are also lighter due to their use of high strength synthetics rather than stainless steel so they will not rust in salt water. They are the latest thing in boat hardware, are a direct result of developments for big expensive race boats, and you will have them on your new Mystere. How cool will you be?! Because this is a 6/1 low friction system, a ratchet is not needed (for comparison the Wave comes with a cheap 4/1 system w/o ratchet). There is a traveler and a 4/1 downhaul. The spinnaker came with a simple Harken bullet block so I requested a substitution for a fairly new kind of block that automatically ratchets when under load or free-wheels when sensing little or no load. Two vendors make blocks like this – Ronstan and Harken. For only ten dollars more per block ($20 total) we could get the Ronstan “Smart Ratchet” blocks ($40 retail each at West Marine) so I made an “executive decision” to have all the boats equipped that way. While this increases the cost of the boats a little, based on my cat spinnaker experience, it is well worth the money and the big discount made it an easy choice. This will allow much easier handling of the spinnaker under load without adding any drag that using a normal ratchet block would. The jib blocks are Harken big bullet blocks with Harken cleats.

SNUFFER SYSTEM – This is a fairly recent spinnaker handling innovation on the cat scene. The snuffer fits on the end of the spinnaker pole and accepts the tack of the spinnaker at the front of the snuffer which has roughly the shape of a tennis racket or fish net. A tubular spinnaker bag attaches to this and tapers down along and attached to the pole towards the mast. The spinnaker halyard goes from the mast to the head of the spinnaker and there is a takedown line attached to a patch sewn about in the middle of the spinnaker. The other end goes into the snuffer and bag and out the other end near the mast. When the spinnaker is raised with the halyard, the takedown line goes out with the spinnaker and you just sheet in. To retrieve the spinnaker, the halyard and sheet are released and the takedown line pulls the spinnaker right into the tube. It is very quick and easy to do and keeps the bag off the trampoline. This was not made standard because of the cost but, please, everyone get this, you will be glad you did. While $200 is not inconsequential, it is a bargain price for this system.

TRAMPOLINES – are mesh and have no stitching to wear out – they are all heat welded and are one piece construction for convenience and comfort. They slide in grooves on the front beam and along the hulls and lace up at the back on the rear beam – very easy and quick! This also means no grommets to wear out and less splashing from unwanted openings. There is a front pocket for halyard stowage.

HIKING STICKS – are aluminum and extendable so that sailing with or without the trapeze is easy and comfortable.

MAST FLOTATION – the mast sections are the same as used on the Mystere 6.0 (pretty large) and the masts are sealed. We will sail the boat and capsize it the Saturday it is delivered so that we will know what to expect ASAP. We can always get a group order for the bobs if we want them.

TRAPEZE (S) The boats come with one set of trapezes which is just right for single-handing. Yves (by request) will bring extra sets of trapezes to sell at delivery for everyone who wants to sail double-handed. We do not know the price yet but it will be cheaper from him than anywhere else. We will pass on the price when we know it.

Mystere and the 4.3 History

In 1980, Yves Sansoucy started manufacturing catamarans as his sailing school had difficulty obtaining parts for their imported boats.  He started with larger 6.0 meter boats and moved to smaller boats later.  The 4.3 began its life in 1999 as a Mystere Tyca designed by Alain Cumming for French training schools.   A sudden dip in the economy in France left Yves with excess stock of 4.3’s.   Yves contacted Mike Fahle, a long time Mystere racer, and the wheels went into motion.  As a complete volunteer effort, Mike led the Ohio sailors through the delivery of 30 new boats in April 2001.   All of these were committed over a few months, sight-unseen, with only a few grainy pictures of European Tycas.  The boat filled a void between the simple Hobie Wave and the popular high-tech 20’s that were really too big for small lake sailing.  Following quickly from the popularity, Yves agreed to provide the 2002 US Youth Nationals with 20 4.3s.   Mike again orchestrated the sale of these boats mostly to Ohio sailors.  The result has been a solid, sustained one design class for Ohio and neighboring state sailors.   A few boats have strayed as far as Texas and Florida but the majority remain in the Ohio area.  With the decline in boat sales and general economic conditions, Mystere is no longer producing boats.

Current 4.3 owners now deal with the irony of limited manufacturer part availability.   The fleet Yahoo discussion list remains the best source for resourceful, creative, smart owners who can suggest alternatives to any needed part.  The sails, tramp, lines,  blocks, and standing rigging are all commercially available.  The mast and beams are so bulletproof that replacement will likely never be needed.  For the remaining few Mystere only parts, if it was made by man once, it can be made by man again!
