My rudder was soft from saturation. My page
marcthesailor@blogspot.com has extensive pics.
-Cut skeg off
-dropped the rudder.
-Cut open the starboard side
-Clean out inside well
-Re-glass the cutout and reinforce the leading edge of rudder
-had a new rudder pintle fabricated out of high quality stainless and added gussets on the underside for added strength (as mine had a slight downward bend from pressure)
-drilled holes and re-filled rudder with solid cell marine foam ($400/gal)
-installed rudder
-***RE-Glass skeg back in place (new skeg not necessary unless the original had been badly damaged in a collision.)
Better than new.
