Hi All, Great to be learning from you all from the posts so far. So I'm a long time listener.....first time caller. :-)

I'm replacing my main sheet blocks on my 375.
The current original (2011) blocks are Lewmar, I think 70mm synchro.
That version didn't have a shackle but a pin to secure it to the standup base.

I'm not keen to unscrew the base, from the coachhouse, which is manufactured with the base of the block integral to the hole unit. The opportunity appears to be to install a new block with the same slide-in pin rather than a shackle.

I was able to easily knock out the pin to remove the pin/swivel.

Any recommendation on a new and current block that has the same slide in pin assembly? The swivel section that inserts into the base is around 15mm.

Would appreciate some experience from previous 375 owners.

go for Harken ESP Blocks. the problem is that the mastfoot pins are basically too small for the loads
