I've broken ribs as well as hull stringers when
colliding with hard objects on the shore. If you can
avoid such collisions, you shouldn't experience any
breakage. In all cases, the breaks didn't incapacitate
the boat. The skin keeps the matrix of ribs and
stringers in place so your boat doesn't unravel. In
some cases I didn't even notice the breaks until I
replaced the skin.
The breaks that I did have were in relatively soft
wood, red cedar stringers or willow ribs. I have one
baidarka with oak ribs where I haven't experienced any
breaks.
Breaks tend to occur in the rounded parts of the hull
or where the ribs are lashed against the keelson.
If you haven't ribbed your boat yet, you might
consider going with steamed oak or ash instead of
wrapping individual ribs.
