Ok, so I've been browsing for a while now on these whoopie slings and had a few questions before I start the journey to the dark side.
Currently I'm running a HH hyperite with stock suspension and have concerns about the longevity of the line used in conjunction with the basic lashing HH uses to secure the hammock to the webbing, IN ADDITION to the longevity of the line when spliced together with another line to add length to reach trees spaced further than the stock suspension allows.
1) I was reading that the nature of the whoopie retains most of the line strength, AND eliminates most of the localized stresses in the line. I would imagine that this is superior in terms of strength retention when compared to a line with an extension (two lines tied together), but what about the basic lashing?
As far as I understand when any line has a knot it does put a lot of stress on the line because of the tight bends in the knot. Whoopies use splices instead of knots so there aren't really any tight bends to reduce strength. Also by the "the basic lashing" i'm guessing you'r referring to the larks head that attaches the whoopie to the hammock (I've never used a HH)? If so I don't think it would put too much stress on the line because there aren't really any tight bends since it's being wrapped around the hammock material.
2) Is the longevity of the line severely comprimised when using an extension or a lashing when compared to a whoopie?
3) I've noticed different size line being used to create whoopies. It seems that a larger one would be easier to splice and would hold more weight. But would also be heavier. What I've seen used most (7/64") has a test of 1600lbs. Thats sufficient to support any amount of weight I could put on it, even with a 80% line derating for a safety factor (extreme, I know). I guess the question here is, why not go smaller? Would a smaller line put more localized stress on the hammock connection, or the webbing connection at the tree?
Some people do go smaller! You can use dynaglyde, it is smaller and lighter but is not as strong. You need to remember though that yes, 7/64" is rated for 1600lbs but it WILL NOT support even a 1000lbs person hanging in a hammock. There are other forces apllied and someone who knows the numbers on this i'm sure will reply. It has something to do with trigonometry...
4) Converting an HH, is this a simple process? I'm assuming it voids any kind of factory warranty, but is it reversible? (I don't have my hammock in front of me to see for myself.)
5) I read that people use about 12'-14' of line per size for 6' of adjustment. Seeing is that how it's pretty much a rope doubled back on itself, does that then indicate 6' adjustment PER SIDE? So, roughly 12' total?
Yes, if you take a 14' line and make a whoopie the longest that whoopie could be is around 6' since it's doubled over on itself. So a total of around 12' if you figure in a whoppie sling on each side of the hammock. If your worried about using so much line you might want to look at UCR's its basicly one line with another 2' burry section over it so you don't have to double up the line (that's another story though)
6) After the final back splice in the end that hangs out (IDK what it's called.) do any of you tie a stopper knot to keep from pulling your splice through on accident?
The tail end normally has a little stopper splice in it, it's basically the end of the line pulled inside itself. That way the end doesn't fray and it is also thick enough that it won't get pulled through the burry. Some people put a beed on the adjustable loop end to keep that from getting pulled through also
7) Does having a whoopie limit the minimum distance of your trees?
Yes, if you consider the fact that there is a fixed loop that attaches to the hammock and the lenght of the burry for the adjustable part, the smallest you can make the whoopie sling is around 2'. I use a continuous loop at the end of my hammock and attach my whoope sling to that, so if the trees are really close together then i can just attach the continuous loop to the marlin spike hitch instead of the whoopie.
8) Do snakeskins interfere with whoopies too much to be considered worth it? (I know some people plain don't like em, but I'm not aksing about that here.
)
Hmmm. I think I'm out of questions for the moment. I'll come back if I think of anymore.
