    Posted: 17 April 2023 at 19:03
We have just purchased a 2011 400 and are delighted. We notice that she is not pointing well and are questioning whether the route through the blocks (no traveller) is correct. A neighbouring owner has told us we are missing a double block. 

 

I can't find any diagram in the official web site or manual, nor on this forum. Would anyone be able to point me to a diagram or provide a photo? The photo below is the best I can find. 

Any advice on how best to tune for upwind would be appreciated.

 

Thank you.

Paul

The starboard block is hidden behind the life raft in the photo, but I would expect there to be a block. 

In that case the main sheet should start from the boom attached block's now empty becket, go through the starboard block, then through boom block to port block ...

I guess the current set up's purchase ratio (? is this the correct term?) is less than 1:3. Adding the starboard block would double it.

I have 371 with the main sheet at the end of the boom with 1:6 purchase ratio, but I've added an additional block that results 1:12 purchase ratio for heavy weather tacking. Your current set up is definitively undersized.

Additional comment: I disliked the Lewmar blocks Hanse installed: their cheeks are soft plastic which bend easily, and the sheet may end up between the cheeck and the rotating sheavel, potentially damaging both the block and the sheet.

I've changed my Lewmar blocks to Harkens, which also have less friction. After paying for the Harkens I know why Hanse installed Lewmars...

I connect lines to the end of the boom and run them snatch blocks attached to the rail and to the primary winches. It allows me to pull the boom further into the center than you can accomplish with the main sheet alone and that helps pointing. At 8 knts we can easily sail a 28AWA. 

Something else to check is your back stay tension. If your mast is raked it will affect your pointing.

Chrisn - I guess my goofing off this summer is why I missed your comments regarding a line off the end of the boom to adjust sail trim. This is exactly what I have been thinking about doing on my 430. 28AWA. I like it! I find that when I get into the low 30s, my boat starts to complain. How do you attach the sheets to get far enough outboard? My toe rails are solid aluminum. Ive considered adding a piece of aluminum machined to fit inside the toe rail and span 3 or so fasteners (hope this makes sense) so I could then drill through the toe rails to attach a block.

I dont have an adjustable back stay but the pre-bend in my mast is pretty significant. Sailor friends of mine are somewhat in awe of it - having a rigger verify it is on the to do list.

My boat is a 2010 407e that came with pad eyes and blocks on the rail and aux winches for the gennaker. I run the lines from the end of the boom, through the blocks and to the aux winches.  

The setup works well and helps us point. Also allows us to fine tune the main.

In this thread there is an alternative way of controlling the boom mounting blocks on strops which I know works well.
