Mast base blocks SWL 850 kg and 6 mm clevis pin

Message Rating: Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi again 

I have updated the initial message of this thread with:

correct information from Rutgerson 
updates from Garhauer Scandinavian retailer, a hidden block araised on the shopping radar 
Barton added but unfortunately no block with 6 mm clevis pin located
Now do I have a good foundation of information to decide which block to buy, Rutgerson do have a good price but not the best SWL for 6 mm clevis pin. Need to sleep on it before acting....

	Brufan, you can upload photos that are re-sized prior upload or tweak the size of the photo when doing the upload. This is the same photo, tweaked by my at upload click on Preview, wait Width 4288 -> 714 Height 2848 -> 474 I believe it is much easier to see the photo directly in the web browser and not being forced to manually download the photo to your computer to change size of the photo to view it. A friendly tip to you and others that upload too large photos Sparcraft mast collar has a complete different foundation, on our yacht from 2005 are there round mast collar pins around the mast base which limit the selection of possible blocks. The blocks need to support connection to the round pin from the mast base. Photo from internet showing the design I think the Selden system is much better than the system we have so I can only congratulate you to have a Selden system Edited by skipper - 20 June 2011 at 20:36

	Greyghost and others with Harken block are you pleased with Harken 6095 and Harken 6096 (SWL 750 kg, 57 mm sheave) at the mast base? If so a conclusion could be that a SWL of 750 kg is enough for a Hanse 341/342/350 when using welldesigned blocks Rutgerson B300601BF12 (SWL 850 kg,60 mm sheave) would be a good choice from a cost-benefit point of view.

	Skipper, Thanks for sharing your experiences. I'm sure I am not the only one who is concidering replacement of the Lewmar blocks. You asked about Harken 6095 and 6096. I suppose the Harken 6105 might be better choise. It has the swiveling forkhead just like the original Lewmar blocks. I don't know if it is important or necessary, though. The Rudgerson you mentioned doesn't have it, either.

	Merinalle, thanks for your suggestion, I added 6105 to the first message in this discussion thread to get a full overview at the beginning (summary). 6105 do not support 12 mm line which I and others use for the sheets. The swivel function should not be needed on the block due to that the Sparcraft mast collar pin should be able to rotate itself. This can in many cases been stopped by the shipyards method by using to much of sealing/Sikaflex. In this old thread can you see how the mast collar pin is fitted to the mast http://www.myhanse.com/forum_posts.asp?TID=246&PN=3 One possible root cause to block crashes could have been the SWIVEL function that could mean that the block rotate and then under heavy load has 90 degrees from a force direction point of view. I would say that 6 mast collar pins could be set to the right direction and used by 6 blocks with fixed toggleheads due to that the mast and the organizer on most sailboat are fixed:-) If the 2 higher mast collar pins used by lines from the boom can rotate it would also be possible to use blocks with fixed toggleheads. If these 2 pins doesn't rotate blocks with swivel could be a better solution. Rutgerson has 600 block with fixed togglehead and with swivel it is up to the Hanse owner to chose.

	Skipper, I have had no issues with my Harken 6095 and 6096 mast base blocks since installation. So yes, they seem to be working well. First I blew up a 75mm Synchro triple mainsheet block, which I replaced with a Harken equivalent. Subsequently, I blew up a 60mm Synchro mast base block, so I replaced them all with Harkens. Both failed when the line got between the sheave and the cheek of the block. I don't like failures... Be aware that the 6095/6096 blocks do not have a built-in swivel, so you must be sure that your mast base pins are free to move to allow the block to align with the load.Sometimes Hanse puts a bit too much bedding compound beneath the mast collar and the pins do not move freely. :-) Cheers, Doug

	My SELDEN mastfoot blocks are 60 mm (SWL 1100 kg). They seem OK for the job on my H355. By the way, does anyone knows the load on the assym spinnaker (82 m2 approx) tack block.

	MAST BASE BLOCKS Yes it is true that the blocks with fixed troggle-head needs to be aligned but our original mast base blocks with Sparcraft label has since start also needed to be aligned. I can't see a need of swivel at the mast base, at least on our yacht is the mast standing still and the organizer seem also to be rather fixed GENNAKER BLOCK I have a gennaker (roughly 85 sq m) and use Selden PBB 70 single block (SWL 1500 kg) connected with webbing to the aft cleats on both sides. That have I used only this season but so far has it worked fine Edited by skipper - 22 June 2011 at 10:16

	Rutgerson do have a similar block with swivel which I added to the SUMMARY POST, order number B300601BT. Did have a chat with a First 31.7 sailor and according to him is it only stainless steel balls that rotate in ball bearings when the block is under high load. Rutgerson have been very promptly via email and so has the Scandinavian retailer of Garhauer blocks but contact via Garhauer US Web page isn't the recommended path. Lot of companies are using social media like Facebook or supporting customer via different web forums, if you need support by Garhauer US use telephone. Based on feedback/info from: Greyqhost and others with Harken blocks supporting SWL 750 kg Hanse sailor with Garhauer 30-LS SWL 900 kg Spinlock XAS clutch coping with max 575 kg First 31.7 sailor thoughts about ball bearings did I tonight order 8 Rutgerson block B300601BF12 (sleeve bearings SWL 850 kg) via Rutgerson web-page. The future will show me if this decision was smart, today am I strong in the believe that it is the right way for our Hanse 342 used mainly for cruicing and at a few sail competitions. Thx for the discussions Edited by skipper - 22 June 2011 at 10:06

	Yesterday did I bought Rutgerson stand-up spring for 500 series art no B100542 (spring diameter 30-31 mm, spring weight 10 gram, single block B300601BF12 weight 181 gram). The spring end with the largest diameter is towards the Sparcraft mast collar (deck side) and the other end of the spring did I need to increase the diameter just a little to get it over the tooglehead. (Stand-up spring for 600 series doesn't fit to 600 blocks with fixed toggleheads.) When I mounted the springs and blocks did I notice that the 2 mast collar pins closest to the cookpit is higher than the 6 pins closer to the stern. All pins rotated when I moved the blocks, the 2 highest pins must be able to rotate easily due to that they are used by lines from the boom which is moving. (The mast is standing still and so does the organizer.) Looks fantastic, I will upload an image to show how it looks around the mast and also an image showing the hugh difference between the small 45 mm blocks from the shipyard and the new 60 mm blocks.
