I managed to overtighten my canvas boat cover last season and in the
process pulled the anchor roller through it at the bow, creating a nice
18" rip. Had a couple of other minor rips and tears. Got it all repaired
at a local boat canvas shop for $60, and the shop sewed on double
patches of vinyl at the bow where I pulled the cover too tight over the
deck hardware. $60 is a lot better than $400 for a new "semi-custom" cover.

Still evolving a quick tie/release system for straps that tie the cover
to the trailer...

Cheers.
