Turning block questions. What are recommended at the mast base (dia; ball bearing vs. carbo)? What is SWL? What are typical load ranges or how do I estimate loads on common lines, e.g. halyards, mainsheet, boom vang...
Thanks

I used Garhauer 25-11SL blocks on my mast base. The SL stands for Stainless Lite. My boat came with two 30-11SL which are much to large, but I continue to use them since I did not want to spend the additional money to replace them. The 25-11's are $18.63 each which is very reasonable.


The large block aft is the 30-11.

Hi Gerry,

Take a look in the tech tips section. Lots of ideas there for running lines aft on the cabin top.

I had Garhauer blocks on my 82 and have mostly Carbos on my 89. Carbos don't scratch things. I was happy with the Garhauers other than that but hated their two line Genoa cars, I now use their single line genoa cars and like them much better. The biggest knock against garhauer is the thickness of their material. Compare to a Schaefer block and you will see a huge quality difference. As long as you do not step on the Garhauers they do fine but they can bend. As for line sizes it is a fairly long discussion based on your objectives. I use a place called Layline.com and if I have questions i call and talk to them. They are sponsors of our Nationals. The point that needs to be made is that technology has made line so strong that you can get any size you like and it will far exceed your needs. Note my halyards are the small lines in the photo below, that keeps weight down aloft, price down, hardware sizes down. There are many photos of my 82 and the lines led back at my site. On my 82 I led 4 lines back per side, on my 89 I am trying for a less cluttered look and am leading less lines back. Remember there are different ways to skin that cat, on my 89 I use a BoomKicker rather than a topping lift to reduce one line. I have left my outhaul on the boom to reduce another, those are some of the choices you need to make.

I have Garhauer at the mast base and genoa cars.Good looking,rugged and inexpensive.SWL is safe working load.I did alot of research last winter on loads for various blocks and it appears that Harken rates thiers on the conservative side.They have an excellent website and catalog that will answer some of your questions.Line angles and whether or not the lines are winched will change your loads considerably.

Frank-I have a few older Schaefer blocks that don't look as heavy as the Garhauer blocks,have you had any problems besides bending?

I cannot agree with you on ruggedness. The shackles that come with the 25 series are an odd size and use really small clevis so if you loose one you are not likely to have one that will work lying around. The springs they ship with blocks do not fit, so they are obviously an afterthought. I think Garhauer is great stuff due to its price and its appearance and I respect what they have done with the Catalina "opportunity". I also like the fact that you can talk to Guido and get things done even though the lady who answers the phone is often more confused than anything else. I do not intend to buy any more of their products. When I was retro fitting the 82 Garhauer products were just the ticket, now that I am working on my 89 I am buying Harken, Schaefer, and Ronstan. The motor mounts from Garhauer are awesome.
