G'day,

There is only one way to estimate the time, and that is to get some
experience and work from there. In my opinion, it will be a lot
quicker to build panels than strips. I would not, however infuse them
as the time taken to set up is too long. Bagging on the table is so
quick that you don't need to infuse.

I start Solitarry in 6 weeks. There are 12 large panels, plus another
to cut the smaller pieces from. These are for the hulls, decks, beams
and mast. Average a day per panel, including rebates and deck edge
radii. They will be wet laminated, then vac bagged on the table.
Secondary bonding and additional glassing will be done without
bagging. Assembling them will take the same time as joining the
parts of a strip planked boat. The shaping of the polystyrene bottoms
(both systems need the ends shaped) is about the same time as the
rough fair of the strip hulls before glassing.

In my ever confident fashion, I expect the 15m with 2 double berths to
be sailing in about the same time that it took me to strip the hulls,
decks and beams of the 10.5m Harrigami. Time will tell.

regards,
Rob
