Hi Rob,
You're probably right on building time for bare tube, thing is all the add ons. Like the barbs keeping the boom in place , sailtrack (which was also homemade), hounds, padding for the halyards leads and so on.
And everything has to finished to an exeptable level (well, at least most people do ;)).
Remember this is about comparing an easyrig to others. So we're talking about a balestron boom. An una rig boom would be lighter loaded so less material, and definitely much smaller.
With the swing wing all the extra stuff like the wishbones on the mast are lightly loaded. So it't just a matter of laminating a couple of layers of wood around a simple jig.
I suspect the swing wing would be (much) cheaper to build.
The masts on the Tiki 30 are tapered, hollow wood.
regards, Rudolf
