In *really* rough numbers that equals 20 man hours per sheet.
What kind of boats have you been building? Simple open boats? Cabin
cruisers? Speedboats? Sailboats? Does this price include sails and related
gear on your sailboats? Engines on your power boats?

Bruce,
I'll hit just a bit over 800 hours by the time I'm done with my long
micro. I'm at work and don't have my "shoebox of receipts" with me,
but my build is around 15 or 17 sheets of ply (with the hull exterior
sheathed in 6 oz glass). That puts me around 53 hours per sheet. I'm
also in the ball park of 1 gal per sheet of ply.

Also when you are putting down the triax you cover it
with a layer of 7781 or one of the lighter satin finsh
industral clothes you have less to fill and a smooth
finish to start with. A lot of times you can pull the
resin you need out of the glass under it so you get a
higher glass to resin content.
I'll tell you I wish I had known the trick a lot
sooner! I know it can cut the fairing time in half
over say just mat or some of the heaver boat cloths.

Oh I think it was Dave Gerr that says for time take
the weight and divide it by 3 or 3.5 and that will
tell you how many hours you will have in the boat.
Dave said you can build a boat at about 3 to 3.5 lbs
per hour. I think I have the numbers right. Some
people are a bit faster and some a bit slower. This is
also for the over all project mind you.
A couple of projects I have worked on tend to prove
the numbers about right.

Hmmm to do just the layup should take about an hour or
two. But to get it all ready for paint I would guess
your time is about right.
You are going to have about 1 and half lb of resin for
every lb of glass cloth. I think is the rule we used.
There was some place I saw a chart that listed how
much resin to how many sq. ft. of a given cloth
weight. I can't remember where I saw it.

For the bottom of a boat like Tahiti I would recommend 20 oz triax cloth. I used it on the bottom of the AS-29. It takes a ton of epoxy to fill the weave, but once you do you will have a bottom that's near bullet proof.

Just for fun, I am estimating the time to build a Tahiti... And, I am
curious if others in this group have kept records of building data.
For instance, assuming the plywood is 1/2" and that all plywood gets
sheathed in 6 ounce cloth and epoxy, the estimate could be based on a
simple count of sheets of plywood.
Here is my educated guess: (On average), one sheet of plywood takes 6
manhours and half a gallon of epoxy.
