Take a look at this new sheaveless block by Ronstan.., extremely light. Only can handle line up to 3/16" or 5mm. Could be utile for some lightweight rigging stuff.

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?

Back on the imaginary boat build I see. Please keep us updated with pictures.

I'm freaking hilarious!

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-cell
I've used it, nothing super fancy but easy to use. I'd love to try it on the F18 one of these days.

I think it could be a good alternative to small stainless rings like we use under the tramp and inside the beam, or anywhere else some line guidance it needed.

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.

Sure, I'll pick one of those up <img src="<>/crazy.gif" alt="crazy" title="crazy" height="15" width="15" /> ... $4,500? I would rather have a set of sails.

Closer than you think if the bank dude wasn't such a pr*ck

I'm too fat for an F18 anyway...

?

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).

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

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. <img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

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.

Argument? Nah..that never happened. I just got tired of the endless drivel of hateful political stuff in my newsfeed.

The French solo racers started using these where possible a few years ago on shallow angle leads (barber haulers and the like) to replace blocks with moving parts that could fail. These are lighter too. There are a couple of different varieties now - Hall makes a version as do Schaefer and Holt. It's a polished aluminum ring.

What he said. Great for low angle or high load cascades.

All ya gotta do is take me out of your newsfeed, bonehead. A tech savvy guy like yourself is bound to know that. You must be sniffing to much t shirt ink and vinyl fumes. Schneider doesn't have that excuse.

I went the extra mile when you reposted ridiculous stuff we'd already agreed was false and hurtful. Are you noticing a trend? Reckon we all have poor character and swelled heads? There's a difference between busting your buddy's balls and stoking the coals of discord.

Todd.... Perhaps I am just old school. I don't do well with the Push technology that facebook provides... It demands that I opt out out of particular news feeds to have any fun factor with FB.. I did not find the entertainment value high enough to go to the trouble and manage you. So, whether it's your political rants or somebodies drivel about cupcakes and babies, or all of the marketing BS that comes through... it is a PIA to manage.

Obviously, people could manage what they post on their own.... That old social rule... No politics or religion at dinner would work for me in this context..

So, at the dinner table, you can't just get up and leave when the politics and religion piss you off... I would much rather pull the information that I want to read when I want it. I can go argue politics on political sites when I want.... and leave when I want.

Mark, You did the right thing. you don't like what I have to say , go away as far as Facebook goes.
Dubs, Extra mile, Please.Yep, I see a trend . The socialist sailors that I know don't want to hear my opinion, 'cause it chuffs 'em. As far as your concerned you won't recognize any truth that doesn't agree with your progressive view, which you constantly deny having (

I'm not a liberal

). If you can't even stand for what you believe in and wear that badge ( rather I agree with it or not), I've got no use for you, so good riddance, twice. I've had the same view for decades, if you never bothered to find out, and it took Facebook to clue you in, well I guess you never knew me.
This is not the place for this . I was called out I answered. I'm done typing about it. Keep harping,troll away, as I know you will, but don't expect a response....Unless you're Ding.

Oh man, here we go....the only reason I get chuffed at your opinion is because it is totally inflexible, un-researched, and you won't quit trying to ram it down everybody's throat. For instance; if you were to study the true meaning and history of socialism you would understand that not only are we not experiencing it but also that to be liberal is not to be socialist. I'm sorry we destroyed this thread...I won't bother with this topic anymore.
