John,

When my rudder did what your daggerboard did, I cut out the wood AND filled with resin. Still fine 8 years later.

As far as the paddle, maybe sand away the loose bits, fill in with wood flour and epoxy (especially under the plastic), sand and then cover the repaired part with graphite/epoxy mix. If you mask a nice straight edge, it'll look as if it was designed to have a special black tip.

Good luck,

Laszlo

Thanks Laszlo. So no fibreglass needed on either you reckon? What if I keep being mean to my paddle? PS: my kickup rudder is almost as new, despite constantly being dragged up beaches and ramps....

I don't think that the daggerboard needs the glass since that was a one-time event.

Glass could help the durability of the paddles. I didn't suggest it the fisrt time because I thought you had learned your lesson :-)  but if you're going to keep up your ungentle ways definitely add glass.

Don't forget, on the paddles, to get the repairs as smooth and fair as you can since you don't want to add a turbulence generator.

Great advice, Laszlo!  I'm going to graphite my brand new oars while I'm doing the bottom of my PMD.
