The bamboo poles are poor man's push poles. I put a slot in one end and epoxied a foot (3/16 x 6") piece of cypress to make a tee so it won't stick in the bottom, and the other end I filled with epoxy so it won't split and you can stick it into the bottom to stake - out in shallow water, basically another way to anchor. We used them yesterday in water to shallow to effectively paddle.
That is a good point about a temporary thwart to keep any deformation at bay. The sides seem pretty stiff, rub rails, and inwales, but it couldn't hurt to be safe.
Check out tie downs under the hood, I cut some nylon strap and put it under a fender bolt on each side. When not in use, just tuck back down under the hood
The fishing trip was mostly that, fishing, one itty bitty trout, although I did get slimed releasing him. The anchor system worked well. The skiff has a small bowsprit and anchor roller, and with the swivel seat, by raising my legs, I can spin the seat 180 and cast across and down wind. The seat did not seem to raise the center of balance noticeably, and the few extra inches of height sure made it easier to get up and down. On the pirogue, we put an anchor roller on the stern so he can cast in the same way, across and down wind. The kayak paddles had mixed reviews. Much better for upwind propulsion, but the water dripping in our laps and water in the bilge leaves a lot to be desired. Down wind, we were able to use shallow angle strokes, but up wind digging in for more power, we got drenched. For any one interested in the relative performance between the skiff and pirogue, the pirogue is considerably faster. The son could put 100yds between us in 5 minutes. I am 60 lbs heavier, I had a big cooler with 6 drinks, 4 bottles of water and 10 lbs of ice, and the boat itself weighs 25 lbs more, plus added wetted surface with the transom. No big surprise i guess.
