Brendan, Thanks for the reply. 2 inch is the length where I notice the separation along the trailing edge. Actual separation distance is less than 1/16 in. at the training edge. Yoshi

:: Definitely a small soft spot can be repaired without
:: replacing the whole rudder. However the 2" separation
:: indicates some delamination is occurring which is
:: important to address. Especially if the boat lives in
:: the water, this delam will spread until your rudder
:: falls apart.
::
:: First, determine if it is the only soft spot and the
:: extent by tapping the entire rudder (hard plastic handle
:: of a screwdriver works well). You'll hear a notably
:: different sound over delaminated areas.
::
:: The best repair involves grinding away all the glass
:: over delaminated areas, filling low spots or replacing
:: foam as appropriate, and re-glassing over the repair.
:: Then the gelcoat needs to be repaired as well.
::
:: Small delam can sometimes be repaired by drilling holes
:: and injecting epoxy. This might be worth a try if the
:: boat is dry-sailed, but if the boat lives in the water
:: best to fix it right as this fix might still allow water
:: to intrude.
::
:: Replacing an E27 rudder is non-trivial and
:: expensive--best to repair the one you have.
