I think the material cost per boat was under $200. The boats took me a couple weeks to build. I did most of the work myself, the only help I needed was when it came time to fit the bow. I worked on it a little here and a little there. Material like the luan and PL Premium, and zipties were purchased at Home Depot and the Fiberglass, Resin, fiberglass cloth was purchased through US Composites. You can build two just as quick as you can build one. You just repeat the same step on the second boat. Good Luck and I look forward to seeing your completed boat.
