Is there anything under the car that can be used as a tie off on the Front/Rear and sides without having to fabricate a bracket?

I just inherited my Father's canvas covered cedar canoe - so guess what - I need to be able to stick it on the roof (But @ least I have foam holders on the roof for it).

Any suggestions for tie offs would be appreciated (I know I'll have to put terry cloth towels tied around the ropes to avoid the paint rubbing.
