Re: [harryproa] Re: materials and costs

G'day,

It is indeed for real. On the boat for Maine, which used a bit more
material, these numbers were spot on, and there was not enough waste to
light afire big enough bto boil a kettle. Have a look at
http://www.harryproa.com/plans.htm#material for the complete list. The
materials quantities are correct, but with price changes, i am not sure we
could still do the entire package for $aus20k.

400 gsm is between 12 and 13 ounces. Either will do.
Regards,

Rob
