A stiff mast in GPR will weigth to much or be too bendy,
Which radius are you talking about?

none specified by you.
Here is a homie GRP-mast for a Roamer

And what a real succes it was! did you see the picture where they determined
the mast bend? That is what gave me the impression that GPR is too bendy.

glass is just too
elastic for that purpose. If you want to build the mast yourself, I'd try
a wood/carbon/epoxy setup.
Sometimes more expencive stuff is better. Probably it is in this case.

Sure if you have the money and the experience. As a novice I'd keep it
simple.

Wood for ease of construction (otherwise you need
to make a mandrel/plug first)

No there are plenty of other ways!

Please enlighten me, because i have not found any descriptions of anything
other yet.

and for compression, carbon for stiffnes and
epoxy to glue it all together with some margin for error.
besides, I'd go fo a balanced lug for ease of handling. Just one sail,
relatively easy to make and no long spars or mast needed.
My good, stop that romantic mumbo jumbo!

so you want a long spar and difficult to make sail? I don't see much
romantic in any type of sailrig

...and, why the **** should anyone invest in hours of building a
carbon-combination and for a lug?

Because a lug has one side free of an obstructing mast spoiling airflow (two
if you dip it). If you are making that mast yourself anyway, why should you
not include a handfull of carbon tape in it? Sure a pure carbon wingmast
with a high aspect sail is very efficient, but I don't think most novice
builders can pull that off.

Yes, yes... buy carbon fibers and build a garden trolly ;o)
Actually, I'm quite convinced that you are trying to pull my leg.

If that is how you react to people with a different opinion, I pity you.

You wont get a
high aspect ratio with it, but you should not strive for that on your
boat anyway.
Huh!
...naturally there was no argument for that last part P

Novice sailor, (age?) not racing, practical transporter. I cannot see a need
for a super efficient rig, and I do see some reasons why you would want a
simple rig. (I see no reasons for that super light hull too, for that
matter, you're even planning on an outboard and waterballast on it too!)

But hey you dreamed it up, so you must have a logical explanation for it I
am sure.
