Here is my sleeping on boat setup. Barely visible through the door is a roll-a-cot. It has such a wet-dog look because that night before was a micro-burst deluge and the river flashed while I was sleeping(not during lighting, thunder and burst) on boat(red mud deposit on bank).
The tent is a Walrus Hurricane Hole. It seems tailor made to set up on a boat especially considering that it is a hoop rain fly, hence no center pole to get in the way as with pyramid tents.
Hilleberg makes similar hoop flys(fly pitchable without internal tent). Unfortunately, Walrus and Hillebergs are not cheap tents. Maybe someone make a cheaper hoop.
Note that I can move that raft-flipping-high-back-captains-seat
around to suite the occasion. There was a beach front happy hour the night before. This was back when camping at the mouth of Kanab Ck was allowed.
