Gardner,
It's scary when you see how much time things really take, eh?
But the F-39 time costs are an apple to the Solitarry's orange.
Vertical strip-planking a 39' trimaran in foam, including all the
fairing that will require, is a huge time sink, and one that would
not be part of of a build made from infused panels with simple
bends.
Since the panels themselves will be inherently fair, you could
spend days or weeks getting them to a point that could take months
or years with the vertical strip-planking (assumes you won't be
working on the boat full-time). The Solitarry 2 spreadsheet shows
325 hours getting the boat assembled, not including the masts. So
let's be conservative and call it 500.
Then compare that to how long it would take lay out three hulls
with vertical strip-planked foam, hand laminate it, and then
fair-sand-fair-sand... until it's ready for painting. Fairing
plywood on a workboat is already enough for me, and that's already
flat and smooth. I can't imagine the effort it would take to get
all the beautiful lines in a Farrier looking good enough to take
paint.
The difference in build methods is huge.
The proa then has additional advantages of being made from two
hulls instead of three, having just two sheets and two winches, and
skipping the standing rigging. There's just a lot of stuff you
won't have to build, spec, and fit.
Once the hulls are together and fair, you can then decide how many
hundreds of hours to devote to getting a mirror Alexseal finish and
fitting out the electronics.
My plan would be to get all the decks just pretty close and then
finish them with a rough nonskid, and then have a pro do the
vertical surfaces in two-part LPU. Fortunately I know a builder who
works wonders with Awlgrip and Alexseal, in about half the time that
most take, so that part of the equation won't hurt too much.
It's possible you could finish the full boat in 1,000 hours.
That would depend upon how complex you get with other systems,
though, like plumbing and steering.
Use a sun shower hanging up on the wall, an AirHead composting
toilet, and tiller steering, and you add a day to your build time.
Go with pressure water, a marine head, and wheel steering, and
you've got a few more projects ahead of you.

Hi all,
Some of you probably already saw the post in multihull_builders with this link in it: http://www.fram.nl/workshop/figures/timeandcosts.htm
I have been entranced by the idea of a harry being so much faster to build and the demonstrations of the build of the hulls has been very motivatiing, but I am not really sure how the harry build process matches up with this one.
I expect that the finishing is cut, as well as the shell creation, but some storage really needs to be built for a cruising boat, as well as electronics,etc etc.
Does anyone know how to adapt that chart to a harry?
