Yesterday Lockwood Boatworks did the repair. They got the part from Selden many weeks ago, but the rigger wanted to wait until my boat was launched to do the work. (I got a late launch this year due to my own non-boat related issues.) Lockwood's rigger said the job was straightforward and praised both the quality of Selden masts and their product support. The old attachment looked fine --- there was no evidence of cracking or bad welding.
