: Hi,

: I'm about ready to start planning my second Yost SOF boat (should be covering
: the first, a Sea Cruiser, tomorrow). I'm using PVC for this one, but would
: like to try ballistic nylon newt time, for a more rugged boat (FYI most of
: the lakes I paddle are dammed so have submerged trees, rocks, etc). I'm
: impressed by John's Shaman Kayaks durability, using ballistic nylon and
: polyeurethane.

: Firstly, where do I get ballistic nylon? What sort of suppliers should I look
: for - out here in Oz? Same places that sell PVC or something specific? Any
: Aussies here know a good supplier?

: Secondly, the polyeurethane. Any particular type, or just 2-part (or is
: 1-part OK) from a marine chandlery?

: Thanks, I'm all new to this (but plan to be an acomplished SOF frame builder
: one day!).

: Regards,

Well, I sure can't help with suppliers in Oz, but single part polyurethane is fine. Over here, many folks use ZAR exterior oil based polyurethane varnish. Just about any will do, though, apparently, including just plain exterior paint (oil based probably being better). I can only attest, myself, to the Zar, though.
Other, pricey and likely not available down-under, options are Coelan and "Corey's Goop." Then there's hypalon and neoprene coatings, too....

Anyway, have fun! Looking fwd to pics!
