Post subject:  Ratchet block for main sheet system
Is anybody here using a ratcheting block for the upper block on their mainsheet?

I have been thinking of getting a Harken #2609 40 mm ratchet block with becket, here is the link...

http://www.harken.com/productdetail.aspx?id=4657

I only sail my wave in winds above 10 knots and I don't usually sail cleated. Holding on to the mainsheet gets tiring and hard on my hands even though I have good sailing gloves. I have no trouble pulling the sheet in tight, it is holding on to it that gives me problems.

I was considering a 6:1 setup, but for me the ratchet block seems like a better alternative.

Being a novice, I thought I would ask for advice here. Am I on the right track?

Two things to consider:

1. This block have only one sheave while OEM system has two. Thus, this block give you 2:1 purchase instead of 4:1 of OEM system.
2. Switching racheting action on and off on upper block could be tricky.

Thanks for the reply.

Here is a pic of the upper block on my Wave. Pretty sure it is OEM. I think I know what you are saying. The OEM has a fiddle block. The Harken I posted above has a becket.
So maybe this Harken would work better? http://www.harken.com/productdetail.asp ... &taxid=420

The switch shouldn't be a problem, leave it in the on position for the stronger winds I usually sail in, switch it off if I go out in light air.

CA Newbie, did you get to the Toronto Boat Show this week? I went yesterday and came away a little lighter in the wallet LOL.

Harken actually makes a upper block for the Wave: http://www.harken.com/content.aspx?id=13778

I tried that system and it worked well, but I found that I was still getting tired holding the main sheet, and I'm fairly strong, so I went to a 6:1 system. I like the high winds with the Wave, so the extra purchase is nice. I posted a write-up on another website see here: http://galeforcehobiecat.freeforums.net/thread/100/mainsheet-block-options-wave

I think it was your write-up that I read and then bought the Harken HSB411 - I kept the stock lower block. Seems fine. I don't have enough constant wind to get tired, so I mostly leave it free running and my wife uses the ratchet.

Thanks for the info Tradisrad. I remember reading your write-up awhile back and had thought if I go to a 6:1 the Nautos was the way to go. Great comparison by the way, and thanks for taking the time to write it. I see another poster in the comments section was using 3/8" rope. Are you still using the 5/16" rope mentioned in your write-up? Is that what you would recommend?

Get a 6.1 setup. cranking down on the main is a breeze, and if you really want to you can cleat in now and again to save your hands. My 67 year old hands are still going strong. See all my videos in YouTube under

Yes, I have decided to do just that.

I have watched, and enjoyed your videos. Even learned a thing or two. Thanks for making them.

Absolutely get the 6:1 for high winds. But, remember 4:1 is the class rule, if you plan to race.

What should be considered when deciding between a 57mm 6:1 system and a 40mm 6:1 system?

The 57 will accept larger Dia line but will take more vertical distance so you can get 2 blocked easier with the larger sheave.

Hi Geoff, love your videos. What 6:1 system did you go with?

The larger diameter blocks also use more line. So more to let out or sheet in, so go with the smallest blocks that accept the diameter line you want to use. Not a big deal with 6:1, but it does start to add up.
