Thanks! I called the manufacturer, who indicated that you could "probably" use bleach on the white fabric if it stained. It's designed to resist corrosion from acid, etc.

The problem with the Sonnet is you're practically rebuilding the whole boat if you want to replace your hull. I may stick with black this time around...

: Let me say this, about that: The inland waters I paddle tend to leave stains
: (particularly since I'm rarely bothered to rinse off the boats). White
: will show stains more than other colors. Otherwise, I do kind of like your
: proposed colors.
