You can dock your boat with it, I'm gonna stick to manufacturers' instructions for "life" rope. Interesting concept, however...

Sciurus, welcome to the Buzz.
If you really want to learn to splice, than you HAVE TO GET Brion Toss' book Working Rope Book 5. Here's a link.

There may be good reasons to call it "utter crap." I never made one or tested one so I don't know. However, there is one aspect of the splice that definitely has merit, and that is the woven form of the bury. I thought that was utter crap when I tested it a couple of years ago, comparing it to a standard bury in the same rope (Tenex Tec). To my great surprise, even disappointment, the woven "bury" outperformed the standard true bury by a wide margin. Roughly speaking, a woven "bury" of length X had the same holding strength as a standard bury twice as long.
There is a complication to the woven bury that reduces its appeal, and that is that you can't just leave the tail hanging out--you have to bury it! If you test it with the tail hanging out, it may hold but the rope is weakened right where the tail penetrates it. If you test it with the tail buried, you are really testing a hybrid splice and it is hard to tell which part is contributing what. I gave up testing when I couldn't see any use for it, but you probably could make a reliable full-strength splice that was only about 2/3 the length of a standard bury splice.

Hi there,
The ones I tested were secure, but not strong -- two different things. If security and shortness are what matters for an application, a purely stitched splice might be the way to go. And those can be full strength.
As it happens, I'm engaged right now in developing a short-bury prototype for a very specialized application. Because of length constraints, we must use a tail that is less than half the standard bury length, but must generate over half of ultimate efficiency, in rapid cyclic as well as static loads. It can be done, and without the hoo-raw of weaving.
Analogous example: in wire rope splicing, many "lock tucks" have been developed to make Liverpool splices better, especially to prevent slippage when the load is rotating on the wire. But in one series of tests, by Wire Rope News, the simplest, lock-tuck-free splices were the strongest, and as secure as any others. They also happened to be the fairest.
