I didn't build one of those but I did build a stitch and glue boat 5-6 years ago. I made an 11" garvey skiff boat from plans from these guys

I built the GV-11.

They have a great forum with lots of support for building the boats and they sell supplies.
Good luck with your build, it sounds like quite a project.
