[bolger] folding schooner bottom

Following the thread about the Micro bottom. The plans on the folding
schooner call for 1/4". In the revisions Bolger talks about the
oilcanning in the original and gives the option of using 3/8 or two
layers of 1/4 or 1/2" but says that one layer of 1/4" with a layer of
glass and and the stiffeners drawn in the revisions is the most
efficient solution. I am a little worried about weight because I want
to try to get by with a really nice trailer we already own with a 650
lb capacity. Bolger estimates the towing weight as drawn at 500 lbs. I
was going to use the 1/4 and glass and stiffeners but am wondering if I
should reconsider.
