Hi - I sent a message via quick post - this is all strange to me - sorry. I am afraid I do not know anything about the stringers/transon but I do know we did not do a survey. My husband passed in late October and I am now trying to sell the boat - as a package deal as it sits at marina. The boat was Jim's pleasure and my contribution was the paper work/people work and the reality is (added thought) whatever made Jim happy made me happy. The only other pix I have are those from when we bought the boat at the marina and it was in the sling ready to go in the water. Jim did a great deal to it and he was meticulous about the mechanical needs. If I can be of any further assistance, please feel free to call and I will do the best I can. Thank you for your interest. Please feel free to stop at office if I do not happen to be in NY at the time you may decide to see the boat.
