I built a buddy one for his birthday about 7 years ago, his girlfriend at the time now wife purchased the plans and worked with me on what wood to purchase. It was the Hybrid DE. Built all out of 4mm Okume wood and I used Epoxy 3 system will all 6 oz fabric inside and out. I even used the Okume laminated on the two bulk heads. Took me right around a week working most of my time on Saturday and Sunday. I did not use zip ties like he shows in his videos instead I used an old roll of wire I had on hand to connect the wood. I had plenty of old cork from decoys to use as filler for the putty. A good jig saw is about all is needed to work on the boat with a rasp to round when needed.
The boat did paddle but tracking was rough with no center keel. We had it out on the Maumee River just east of town at the boat ramp paddling. We even floated downstream almost to Antwerp, OH with a group of friends with other canoes to test it out. He uses it a lot in flooded corn fields in North Western Ohio as a layout today or drags it into the Maumee in various places in the late winters to duck and goose hunt.
I am 5'7 and weigh around 190 lbs. Standing in the boat was very stable if needed. I do recommend going with a marine grade wood versus an A grade wood you would find at any store like Lowes. It is slightly more but it will last for a long time when epoxied and glassed.
