@Patrick Corry  that Opeongo hammock looks great.  I've had a Hennessey hammock for years but never cottoned to it.  Because I move around in my sleep a lot the thing was in constant motion no matter how tight I rigged it.  Seasickness while trying to sleep isn't fun.  Seems like the Opeongo might solve that?
As for tarps, coming from backpacking I used to never carry one, but I have wisened to the ways of you lot and realized the value of a covered kitchen/lounge on rain days.  I've been getting by with the hex tarp that I got with my Hennessey a couple decades back.  I oscillate between wanting to reseal the seams on it (it leaks quite a bit now, but substantially better than nothing) vs buying something like a 10x14 rectangular tent for a bit more space, esp for tandem trips with the dog and a friend.
