Hi For Pete's sake,

You are facing the same dilemma as myself - clevis pin holes 6 mm limit your choice of blocks.
My boat is a 370e and I have 57 mm blocks, except for halyards where I have 75 mm. That is when I have removed the 6 mm limitation. 

Why not do the Bernstein solution? It gives you plenty of blocks to choose from.

Hello

I was reading your post.

I have a 2007 Hanse 315...and wish to replace the mast base blocks.

You mentioned the previous owner replace the blocks  to Harken...would you know which blocks they were?   6106 or 6107 perhaps?   These blocks are listed under Harken's Big Block, cruising ESP category. This block can fit a 6mm hole in the mast foot base pin.   Would you know if this block can handle the Main Halyard?    I looked at US Spars/Z-Spars #261 and the working and breaking load are higher on the Harken 6107....so to me its a direct replacement.    BUT...it never hurts to double check...from a different source.

You mention below that you wish to replace the lewmar block...could the Harken 6107 work for you? 
if not could you explain?


Cheers


Hi "For Pete's Sake "

As I am the originator of this post I cannot answer your question directly.

I would therefore suggest you send a PM to "Borjebus" as he was the contributor of the information you require in post 8.

Cheers
