The shipwreck in the Queen Charlottes was when they were sailing Tolfea back home to Seattle from Alaska, having spent the winter in Sitka. The beam under the mast started to fail one hundred or so miles off the Queen Charlottes. I think they limped in under the 9.9 horse Yamaha outboard and replaced that beam with a new one so they could continue south.
