Naples, FL | interesting. For you engineering types out there, what is the easiest way to measure working loads on a line? For instance, a jib-sheet or rotator line?

| These have been discussed quite a bit on Sailing Anarchy. Ferrules such as those from Antal and Schaefer make a lot more sense as they are stronger, ligther and if they fail the failsafe is still in the eye splice. The Shockblock is cool but is limited to a very light load applications which there aren't to many of on our boats. And there is no failsafe if it breaks unlike a ferrule. If you want the easiest way to test loads, spinlock makes a load cell for measuring road loads. https://www.spinlock.co.uk/en/load-analysis/zs-ropesense-2/10-tonne-wireless-load-cellI've used it, nothing super fancy but easy to use. I'd love to try it on the F18 one of these days. | | | Re: Interesting New Sheaveless Block

Closer than you think if the bank dude wasn't such a pr*ck I'm too fat for an F18 anyway...

South Carolina | These look kinda cool, but I'm trying to imagine an application for them on my boat.
I think the inexpensive rings underneath the tramp are lightly loaded and work just fine as they are.
Perhaps the cunningham blocks up by the tack? Jib sheeting purchase? Spin halyard (up top)? Traps?
Haven't had trouble with any of these areas yet. I can see how they might be useful in some of the bunji routing systems for the spin sheet take up and trap lines...but these are more expensive than Harkan's 16mm blocks and I would much rather use the real block with a sheave and bearings. The advantage to this thing, however, probably is with entanglement. If it's in a system that often has slack in it I can see how this would be less likely to mis-orient itself. Perhaps on something like the mast rotation limiter or something.

| Hey Rick, any chance you're about to add the antel type rings to your shop? I'm about to order some other stuff of you and need a couple of small ones (no I don't want the shock blocks). | | | Re: Interesting New Sheaveless Block

South Carolina | oh, wait. That $17 is for a pair of those. That's not too bad and would start to be an idea in bunji or other shallow angle line systems

Roanoke Island ,N.C. | At least you are alive....was starting to wonder. I'm still trying to get over THart unfriending me on Facebook. It has been a difficult time for me. Oh, I probably started that. I don't think he's gotten over me unfriending him yet. You were probably just there at the wrong place, wrong time. Innocent casualty. (why is beheading the act of removing a head but befriending is an act of friendship?). Think pretty highly of yourself much ? Unfriending me because you can't support your argument with facts doesn't bother me in the least, just shows poor character. Maybe you need to plan another addition to the garage mahal to make room for your swelled head.  Ding, I thought you unfriended me. Damn, NSA spiking sailing buddies now. And to stay on topic, I'd guess these "blocks" are geared toward kite boarding, like their little plastic ones.
