Elegant simplicity. Does it have a line to the top gaff to control
twist? Would the top gaff act to some extent as an end plate? Much as
I like the simplicity, I can't help wanting to fiddle with it to make
it go that little bit better.
How would one of these go with a rotating wing mast to give finer
entry and control camber? It would probably require split or twinned
battens though, and outhaul tension controls to do it properly. It
might be better to go the whole hog and use dynawing foil inducers
and their related battens. Or go even further and replace the top
gaff with a batten, enclose the area between the top gaff and the
mast and you have a dynawing.
A problem with all these rigs is how to attach stays to their optimum
position of ~2/3 of the way up the mast and still allow reefing. This
can be overcome with a litle extra weight in stiffening and attach
them higher to the mast or even to the sail.
I would like to see some boat to boat comparisons of the various
rigs on Harryproas, but first we have to get some boats sailing.
