Perhaps this has been addressed in one of the may other threads on HPME lines, but if so, I've missed it, and am wondering...
I want to install new lifelines
on my cockpit
area, and started researching. The guidance I've found suggests that eye splices in those lines should be taken to a thimble or ring to assure the radius of the splice is no less that eight times rope
diameter, because tighter radiuses weaken the connection significantly.
This complicates the making of the lines a bit.
As I was pondering this, it occurred to me that I've seen no such caution re soft shackles. Soft shackle nooses are generally capturing a shackle "body" whose diameter is no greater than 2x the line diameter, and the shackles are used in applications that experience a much higher fatigue cycle rate and possibility of line chafe.
I realize the shackles have breaking strengths greater than the rated strength of the line itself, but since dyneema lifelines
are generally oversized re strength due to selecting a larger size than needed for comfort in grabbing the line, so lifelines should generally exceed strength needed.
Is the concern in one case and not the other simply because of application...the use of the lines as "life"lines?
What am I missing? Or can I simply take the splice to a SS shackle with a quarter inch or so radius without worry (doing routine inspections for chafe or deformation, of course)?
