WChevron,

Nope. The line would then ride against the mounting hardware rather than on the block. Think about it, you'll see what I mean.

That is the advantage of the Schaefer "Clear Step" and these new Harken OSLBAs. They are designed so the furling line when led outboard is both held captive and runs against the block fairlead.

The benefit is that you don't have a tripping line running across your foredeck!

john, i see what you mean. i just ordered a couple of the garhauer ones. i currently have the clamp on bulls eye type. although a little different than the schafer style. over the years, the plastic has worn a groove in it from the sheet rubbing on it.

Andre-

I was using one of the 4702 stanchion blocks, similar to this one:



Given that I had a sprained wrist at the time and a wrist brace on.. and three of the four screws tightened up just fine, and the last one pulled free without even me straining... I seriously doubt it was my "overtightening" it. I didn't feel the block would work under the loads required of it with just three of four screws holding it in place, since they are the only things holding it to the stanchion. I stand by my previous statement—the stanchion mount on these blocks are a piss-poor design and Harken knows it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Thanks for the cautionary note, SD.

But I want to add that I had no such problems when installing our OSLBAs.

They snugged up nicely with the allen key. I did not use the "long arm" of the key, as I felt the short arm was adequate to the job.

As a matter of fact, I plan to replace the remaining pulpit blocks with the model SD embedded above.

Sorry SD, I must be getting "oldtimers" disease. I was sure I read somewhere in your earlier post something like "You can still pull the insert free by over-tightening the screws".

Must have got it wrong again. Damn!!

Just had EXACTLY the same thing happen to me with this design last week...

The little metal insert on the last bolt I tightened pulled out with little effort.

We installed that nifty Harken kit (#7404) start of last season to replace a more cumbersome failing old set of fairleads and blocks, and did not encounter the insert pullout failure during installation (I hadn't been aware of it), so either it was fixed or not all have it. The furling line is now outboard of the stanchions and has been performing flawlessly.

John and others, thank you for posting all this great information which was quite useful to me for my upgrade. Prior to my upgrade, the line was neatly run through bulls-eyes on the inboard side of the bullwarks...but it had it's issues so I decided on an upgrade. Here is my installation using a combination of the Schaefer stanchion blocks and a Harken furler lead-in AirBlock.

The Schaefer stanchion block....Nice solid construction.



To secure it to the Stanchion, line up the hole in the sheave with the hex bolt and do not over tighten. It doesn't take much to solidly secure it in place.



I'm going to try them up high (7" above the caprail) for now because I want them clearly out of the way of the amid-ship cleats, chocks and headsail travelers but I will likely lower them a bit later.





Harken lead-in furler AirBlock for the pulpit.



I'll remove the old bulls-eyes and fill the holes when I get better weather.
