Ahoy All
Has anyone replaced their self tacker jib block? 
Mine is looking very dilapidated, and I'd like to upgrade it. It is the the original Lewmar HYE standard single with swivel and becket. It seems like the life of plastic here in Australia is about 10 years...
Any suggestions please?

thanks!

thanks for your suggestion.. Looks nice. Does that mean you don't need the becket? ie you have a direct connection to your clew board (no extra block?)?

Since posting I also found this on the forum:

Correct, i do not use the becket. line goes directly to the clew of the jib. The lewmar cabintop winch is more than strong enough to pull the sheet. even if it was using the becket, which would allow for 2:1 purchase it would not be enough to pull by hand. Too much friction.

Dont use the block pictured in that forum. Only use high-load. That block uses Delrin balls which will flatten out under heavy load. They are not made for prolonged heavy tension and will not be round for long.

Thanks so much for that. So needle bearings are the go?

Hi I made the post that you are referring to.
What block are you talking about?
The Ronstan RF64100 has a breaking load of 4000lbs / 2 tonne. And has dual bearingsystem.
This is much better than the original HYE.

Hi I am referring to the Garhauer block pictured in the post in the link. The particular block uses Delrin balls which will lose round shape very quickly with a concentrated high load. This is not to say the block itself will break but its smooth turning ability will greatly diminish.

Hi,
thanks both for your advice.
I ended up getting the Ronstan RF64100...
H8jer do you happen to know the length you needed for the Jib Sheet? I will replace mine when I put in the new block.
I can see you have a H370, but I don't think the length would be much different for my boat. Any measurements welcome!
thanks

Hi

Good choice for the blockWink

Mine jib sheet is 33 meters, but from wesailhanse.se it states 31.27 meters is enough.
I searched the forums and don't really see rope lengths for the 320. 
There are 2 threads about rope length that might help you:
(made by me 13 years ago for my Hanse 311)
I also here claim the Jib Sheet length for the Hanse 320 is 25 meters - But I have no idea where I got that information. Perhaps from here? https://www.yachtdatabase.com/en/review.jsp?id=Hanse+320 
(Think that page has got fixed up the length for the jib sheet and mainsheet?)
