I strap this down across the width, midway back in my aluminum Panfish Pro to transport it to the lake. Once at the ramp, I slide it a bit to the side and use duct tape and tape weights to boards that aren't shown in the photo that run the length of the bed on both sides. Once I've made it to the drop site, and locate the channel edge with my locator, I throw out a buoy, move down about ten yards, throw out a second buoy. Go upwind and let the wind blow me between the buoys and launch the bed. Once settled, I go back over the bed and mark the waypoint.
As for your bamboo pots Tom, is it possible you may have a lot more weight than needed to sink them? When I started I was using a lot more weight than needed and they'd go down like an anchor. You may want to do a little trial and error to see what it takes to sink your bamboo pots.
Everything is possible. The impossible just takes longer!
