Not sure if you have bought a tarp, but I use a Black diamond "Mega-mid" (a floorless tent) Take the oars cross wiseand cam strap them down tight, then use short cam straps from ea. corner to the end of the oar. I have used this prob 60 nights on rivers. Very bomber and you still have acess to your drag bag, potty in the middle of the night with out getting up and walking to the rio in the dark and on Grand trips or any trip where it is hot on the beach, it is allways sand free, level, and cooler at night to sleep on the raft! I had Jack make my Paco pad years ago for the frame i fabracated for my 18' Aire Lepord Cat. It is a sick set up.
My boat is the cocktail boat as well!!
Enjoy, and good luck!
