This boat was designed and built by its owner as a high latitude cruiser.

It has twin self standing masts but the sailplan is different. The sails envelop the mast like on the Maltese Falson but are proportionned more like aerorigs with the larger part of the sail area being behind the mast.

The owner quotes impressive passage speeds and that the rig is very easy to control (only two small winches and no rigging) and to reef - dropping like a junk sail.

Interesting concept. I'd say it is closer in concept to Oracle/Emirates NZ in that it is a fabric wing with rigid ribs. Dyna rigs like Maltese Falcon have a single thickness sail that doesn't enclose the masts and is really an updated square rigger. The idea of reefing like a junk is good and the ribs get round the junk problem of a flat or negative camber. I couldn't tell whether the mast and boom are joined together and turn as a unit like an Aerorig or separately pivoted like mine.

Isn't it a junk rigged ketch?

From what I understand, there is a rotating mast with the boom fixed to it. However the boom is articulated (as for Oracle etc) behind where the double thickness sail envelops the mast. Beyond the articulation there is a simple layer of sail cloth.

The masts are 16m each, weighing 170kg made of HR GRP. Carbon was considered too expensive for the relative advantage. The mast is thickest where it transits the deck and then tapers towards the foot.

Seems similar except that the mast is inside the sail which improves laminar air flow and then the boom is articulated.

The builder/owner's first boat was junk rigged but he said that this was better.

Apparently the upwind performance of the junk rig was catastrophic.

He has sailed 50000 miles with it without any significant problems.

Another interesting design point is that the dinghy is designed to constitute the floor of the cockpit. It has a split bow to enable it to nest either side of the wheel column.

Many junk rig enthusiasts have experimented with similar concepts to here but never with rotating masts. This appears to be outside the pale for us - probably because it represents a whole new dimension of complexity.

The junk rig association website shows how it has all been done before.

Now to address the issue of flat sails and poor windward performance, mentioned by two posters. Most modern junks have beautifully cambered sails - either hinges or sewn in camber. On the RTI race we were being overtaken downwind by similar boats with spinnakers (cannot be flown by junks) and then overtaking them later - on the wind. On another, when it was too windy to fly spinnakers, the junk rig ploughed right through the fleet of similar yachts.

Call me a fanatic - but I cannot think of any advantage of bermudan over the modern junk for the average cruising family.

That is a very neat dinghy design! I would have liked to have saved a copy of the photo, but the site wont allow me to.

The yacht is pretty neat as well, lots of good ideas there.
The rig appears to be very similar to the Gallant rig.
Here are some photos of a yacht with a 'soft' wingsail 'Gallant' rig, originally designed by a chap called Jack Manners Spencer in Lymington in the 70's or early 80's.

There was a 29' sailing yacht (called a Gallant 29) produced in the late 80's with a single Gallant sail, but I guess they were not very popular (has anybody ever seen one?)

Another rig with a similar concept was the 'Tunny' rig, designed by Edwin Gifford - I remember reading about how one was fitted to a coracle style home built catamaran that was later sailed by her musician owners to America, but I cannot find any more info about her on the web. I do have a wee booklet about it somewhere, but where.......

The Aphrodite has probably the next best option : a Portland Pudgy.

Look for 'Snipping tool' on the internet
