If those
specs are for real at that price the competition is in for a rough time.

Some of the specifications have been confused and wrong.

I did caliper and weigh the ample scraps of fabric they included in the box
(for patching, I suppose) to confirm that they essentially duplicate the
PVC fabric and construction used by the older brands.

One item of confusion I remember is that they were advertising a number of
plies or weight or something that was obviously (to me, anyway) applicable
to their Hypalon type fabric, not their PVC. But looking at
http://www.boatstogo.com/fabrictest.asp today, they seem to have corrected
that.
