Steve, if you are going to have a yard do the work - I would sail the boat up to Clear Lake (it's about 24 hours to the Galveston Light, then up the bay about 40 miles) and have the work done at South Texas Yachts inside the Watergate complex -they are the best yard on the Texas Gulf Coast - while you're there, you'll see lots of Beneteaus in the yard for bent rudder posts. The yard manager's name is John and the number is 281-334-7245 or 281-334-5141. Even if you don't want to go that far even though it's just a short hop in a boat the size of yours), call and talk to him, get his email and email him your pictures and get his opinion on materials and about what the cost should be.
Paloma is in Ingleside and if I need any major work, I'll sail up there
