The simplicity of schooner Una rigswith an outleader for
down wind work appeats to me and significantly reduces loads needed for
tensioning.
The way I invisage the Farrier system would cost less than a
hundred dollars a beam. It would require two tubes glassed onto the ww
hull, either a sleeve to go around the crossbeam and a couple of tubes
glassed on to it or four short sections of track . It would then need
four steel rods bent on the ends to insert into the tubes or have one
end attached to a track slug. The last item needed is a short section
of roller to clip on the bottom rods to hold them in position and
providing stability in the stretched out position before pulling the
beams into the sockets. If you look at it as an allignment system for
inserting the crossbeams, then you want something like this for the
trailer assembly anyway.
Insert the masts and crossbeams into the lw hull,
attach the allignment system,
winch out the hulls,
winch in the hulls to bed beams into the sockets.
tie in position,
remove the allignment system,
take to water.
On return everything in reverse except that you would have
to either push up the beams or pull out on the top of a mast as you
pulled the hulls together. Somewhere in there the rudder blades need to
be inserted
The email address. I somehow got given a uk address but I
don't know how it happened. It is too much hassle to change and I hope
to pick up a uni address soon.
My history,
Started uni in engineering but drifted into maths as I could
do the assignments in much less time and get much better grades. I was
about to do my honours in pure maths when I got a job on a tuna poling
boat in the summer break and somehow I stayed. FIshing work developed
my practical engineering skills as crew are expected to do the
maintenance and help with refurbishing when in dock. I decided to pick
up a teaching diploma to tide me over when the other work was a bit
slack. I became a single parent with four children which restricted the
work I was able to do. My musical interests turned into paying work
and I started getting students. This eventually turned into full time
with over 40 students in woodwinds and guitar. When all my children
were at uni, I decided to go back to uni myself to study marine
ecology, concentrating on algae, so I went to uni for a year and gained
a sufficient grade to win a scholarship to do a PhD.
I met a very nice person who was given a job as a Dean up at
the Darwin uni and I followed her. So, here I am, touting for work and
surfing with crocodiles (a 2m Saltwater crocodile joined us in the
surf. We had no objections as he was well mannered and didn't drop
in. The local rag picked up some pictures and ran with it)

Good point about the man overboard. The time saved by simply
stopping and reversing is incalculable. I hadn't thought about the
anchoring issue. The reefing is another big item. Not only do you not
have to worry about doubling the apparent wind, you also don't have to
worry about the boat snapping around and capsizing when you're working
on the sails -- the lw hull will simply stay leeward.
Plus, if you get a schooner rig, there will be no flogging of the sails
once you let the sheets out, which is better for both the sails and the
crew.
I see the benefit of the farrier system in theory, especially now
that you've come up with the idea of a temporary system used just for
assembly and disassembly. At this point the difference for me would
come down to cost and convenience: is it cheaper and easier to build
the functionality into the trailer or into the folding system.

You seem to have an interesting history, by the way. You've spent
years commercial fishing, are working on a PhD, teach music, and are
about to go into either lecturing or researching shark fishing
sustainability. That's a unique combo. I've assumed you're in
Australia because you talk about the Bass Strait and the reef hotel,
but your email address ends in .co.uk. Are you in Oz?

I agree with all you've said. Another few advantages.
manoeveability under sail for picking up man overboard and crossing
bars, being able to place a sea anchor over the stern and let the stern
becomethe bow. Much more comfortable than having to put the sea anchor
over the bow. Double ender makes beaching and leaving much safer.
If over sailed downwind then the sheets can be eased
fully and the sails can easily be reefed, rather than contemplating
rounding up to feather and doubling apparrent wind
I reckon extra accommodation could be included in the
Visionarry by flaring the middle part of the ww side of the lw hull
Don't think it is compromising seaworthiness or windage but certainly
increasing the trailing width as it can no longer tuck under.
If the lw hull was rotated at the same time as pulled
out then less room is needed for the mast. That in essense is the
Farrier system. If the Farrier system is connected to a sleeve over the
beams, then the beams can be slid in after folding. If the struts are
then removed then there is very little increase in sailing weight.
