Years ago when a Treeboat guy was planning a trip to the tropics, we burned a 1/4" hole and set a grommet in the center of his Treeboat. Like you, I had some concerns about this drain breaking the integrity of the fabric right where the hammock carries the greatest load. We never heard a complaint from the user. In the spirit of "no news is good news" I assume no problem developed.

But that's not good enough for me to assure you that a grommet drain is ok. Tom Dunlap shares my hunch that a patch of reinforcing fabric might restore the strength around the drain. We're excited to try this now, and give it some serious field testing.

I'll post here to let you know what we find out. In the meantime, we'd love to hear reports from the field about treetop bathing...
