K,

Was able to fix my SR17 by glassing just one side (@ 2'x2' patch).  Had planned to do BOTH sides - and may eventually do so - but doing just the one side seems to be holding up just fine now, 3+ years later.

A towboat service guy got a little careless when unloading my canoe at the LLC drop-off.  My son & his buddy heard the crack but didn't see the damage.  The oilcanning became noticeable about a half-hour later.  Half a roll of duct tape & keeping weight on the weak area allowed them to paddle an additional 8 days.

Good luck!
