Thanks for the answers.
This verifies my plan, have the piece we saved welded on,
I do all the clean up work, i.e. grinding and painting,
then cover with a skeg guard.
Chum, that is step two, because the very tip of the skeg was lost.
Ridge, that is good news and I hope that the shop I use knows of a good welder.
They should as it is in Lewes, De., I am sure this will not be the first time they have seen this.
