I got called in to work yesterday after posting my "delema". But after looking at my set up in the light of day and comparing all the GREAT advice above, this is what I think happened:
Yep, the shirt was touching the tarp. And, the wind was blowing the tarp, for some reason the wind was comming from the ENE, at my house 99% of the time it blows from the WSW, so I was rigged for that direction. The tarp on the windward side was SOAKED, the spectra cord the hammock hangs from (& it''s ridgeline) was slightly damp, but not (I feel) enough to account for the amount of water I had.
AND: the CCF pad I had under my hammock above the underquilt is, well, waterproof, so the water didn't have anywhere to go.
The underquilt and sleeping bag were wetest on the windward side. Yes they were damp elsewhere, but SOAKED on the side against the tarp.
So, I think the wind was blowing the rain under, around (& thru?) my tarp. I don't think the rain was bypassing my drip lines, but I have no drip lines on the tarp, so perhaps some water was (additonally) getting under the tarp that way, I will be fixing that in a few minutes, going to use more pack towel material.
I still feel that having my hammock hanging for over 24 hrs with it raining much of the time was a contributing feature. Something I likely will not do on the trail, or at least not do very often, & if I do, it will be with me in the hammock & I should be able to fix any problems as they arrise.
Thanks for all the help, I would still be on the ground if not for you guys & gals!!!!
Doctari.
