If you mean the block on the clew of the sail, I used a Selden block which was the same size as all the rest of the mast-foot blocks (except for the mainsheet which were larger).  I "think" this was a PBB60 but can't be sure.

If I was starting again might use a dyneema strop with a high load / low friction eye.  Something like:

Next April I will be at my 385 after a long time. Does anybody know the size of the block which is directly at the jib? It is from Selden.

I will change the sheet to 10 mm Race XP.

Have changed the sheet for some 10mm dyneema which now seems to furl and unfurl much more easily so thanks for the good advice. The 10mm sheet does slip through the cam which will need changing as the next job!

Thanks again.  I think that ordering 32m of dyneema, replacing the sheet but having enough for the 2:1 option will be the job to get done.

I'm really grateful of the replies, which if nothing else, reinforce my view that I have a lot to learn!

@samuel. The H385 is supplied without a 2:1 jibsheet (or at least my 2015 model was) and the OP is asking about installing one.

@Goat. I can see I ordered 32m of Race XP from SVB24. From memory, the owners manual specified 27m and I measured the furled clew to track as 4m and added another metre for spare.

The Race XP is very stiff but has proved a good and relatively economic choice.

I have changed the spinlock cams for my three dyneema halyards to larger cams (6-10mm?) but have not needed to do this for the 10mm jib sheet.

If you remove the 2:1 sheeting arrangement that many boats are fitted with when supplied you increase the load on the pulley in the mast plus the load on the turning block at the mast foot & on the clutch at the winch.. If you also reduce the diameter of the sheet then you may risk slippage at the clutch which may (note: may) mean changing the inside clutch mechanism.
Conversely, if you add 2:1 you greatly reduce the loading
There is a fair load on the jib. I do not know how much, but I do know that this year i had the wheel inside a new 50 dia Barton block collapse. (the one shackled to the jib) & my jib is much smaller than the OP's. I think that a 2:1 is worthwhile having.

Oddly enough this year the halyard pulley in the mast head also collapsed so I have had to have the mast dropped to renew it. It has ended up an expensive repair.

I started with the factory supplied 12mm sheet via a block at the jib back to the rail. This made manual furling impossible, i needed a winch.

Since last year I switched to a 10 mm dyneema sheet directly attached to the jib. I can now furl in my jib manually, even my wife can do it.

I swap to a 2:1 very early in my ownership.  
You need a hi-load, light and low friction block... so expensive !
Second : swap the sheet for one size smaller dyneema one (10 mm ?).  Less resistance in blocks
Third : there are hi loads on Jib's block attachement.  Take care of this part.

Thanks both for the speedy and helpful replies.  S&J - can you recall what length of dyneema sheet you required, I can't find this info in my documentation?
