Thanks Wojo and Andrew,
I'm going for it.
Construction of the spars won't happen until next year but I need to make some preparations this spring. There are a few details to work out yet, but the spars, rigging loads, chainplates and overall geometries have been designed. I need to move a few chainplates and fabricate/install a couple heavier ones. I also want to extend the rubrail all the way aft before she goes into the water permanently.
The plan is to get the chainplates, rubrail and diesel installed this spring/summer and then get her off the hard and up into her slip hopefully by late summer.
