9 x 11 fly coverage?

Any thoughts as to whether an 11ft ridgeline x 9 feet wide rectangular tarp will provide enough coverage for me bunking with my son (11 & 10 foot hammocks)? Thanks!

It will for just a little rain but with the shorter sides and the higher pitch required to bunk a heavier rain will bounce off the ground and get you wet... The 11' ridge is just enough coverage from the ends as well so the person on the bottom would get wet from a very minor blowing wind from the side.... You will really need a bigger tarp to bunk... If you have to use it I would use it "diamond" pitch... You end up with a ridge of about 14.2'... Not much side coverage but more coverage at the ends....

not quite the same, but with the $10 Poly plastic rectangular 9x12 tarp I used; I was able to keep two hammocks dry in a driving, pouring, bouncing rainy weekend on the Oregon coast, tho we set it up side by side and with spreader bars between the hammocks... both hammocks were about 9 feet long though.
the sunny pic is of it set up at a local park before the trip.

EDIT: I also had plenty of room on one side for the chairs, and had to pitch tarp a little lower than normal to get adequate coverage below the bottom of the hammocks;

Also; with the 11 ft RL and the 10/11 ft hammocks, you might want to bring along a couple ponchos to hang like doors on the ends of the tarp; run the tarp and hammock lines through the head openings and then tie the sides of the ponchos together over the main hammock, and stake down the lower corners for doors.

So, I'm hearing that length is more important than width when bunking-guess that kinda makes sense. Maybe side-by-side will be worth trying. I'm not likely to be hanging in very cold weather, so in the interest of that and pack weight I hadn't imagined needing a 12 x 10 tarp.
