Second, I don't want to put $1000 or more in a dinghy. If this goes well I'll probably build something a little bigger but not too much, so this will hone my skills for something later.
Having said all that, there are some areas I won't skimp on. The Epoxy. I intend to use this sites marine grade epoxy for the joints and such. Workmanship. I'm going to do the best job I know how to do.
I found some premium Luan from Lowes that is called Moreland Ultraply. it is better than the run of the mill stuff you usually see. From Moreland's site they claim it to be free of voids, guranteed not to delaminate and glued with Marine glue. I wondered if anyone had used it. Please don't call the plywood police!

Thanks for reading.
