self stowing anchor rollers - have you a good one?

[Martin_J]

Ah.. so the aft of center pivot was more to do with getting the first part of the anchor past the first roller.

As to self righting - If the rollers correctly fit the chain (i.e. groove in the center section) then I'd assumed that you should never get a twist. Twists would only happen on plain rollers or if the chain is pulled by hand and dropped back onto the roller but twisted through 90 degrees or more...

I might take a look at some of the Osculati (or similar) complete units and try and measure their central width. Osculati do some standard ones that are slightly more heavy duty and some even bigger.

PS - I was only thinking about this as a potential future project in case I change to an electric windlass...
Will keep you posted though.

I had several quotes, each time, they were both constructed by Sailspar for about £250, who provided a very helpful friendly service (I have no connection with them).

Hi

Got sorted. Was logged in but was using a Samsung tablet which the site didn't like.
Changed to laptop. All now well.

Really good article. Thanks.

I found, in an obscure French chandlery, a tandem bow roller (I don't know if made by Osculati). While it improved the lead from windlass to anchor it did nothing to make my CQR self-stowing. However, changing from CQR (honourably retired due to wear) to a Mantus, the same set-up results in self-stowage about 90% of the time. The only time it won't work is when the anchor-stock enters the rollers upside down.
I'd therefore opine that anchor design is a more significant factor than bow-roller design for self-stowing. I've found the Delta best for both self-stowing and launching, even if it has some weaknesses in performance.
Incidentally, do not discount the fact that anchor chain always twists, even fitting a chain swivel appears to do little to rectify the problem and unbalances anchor-attitude and therefore set. By the time you have the shackle and swivel aboard many will find the distance from gipsy to roller inadequate for all the clutter.

Some notes about the design.

1. This was for an S&S She 33.
2. The boat previously had a single roller of 50mm width.
3. Make sure your design fits your stemhead fitting with at least 1mm spare.
4. Make sure your existing stemhead is not bent or twisted.
5. The roller reefing and forestay had to be shortened and a spacer inserted to allow the unit to pivot.
6. The rollers shown were designed for 8mm chain.

Some of the above points are obvious, but just in case I include them anyway. Good luck, George

Thanks for posting the details of your design, do you have any photos you can post?

I have attached a few images, the only one I have of the anchor launcher is before we fitted an extension below the roller reefing. I also have a rather poor short vidio which I will try to attach.

Cheers for the photos - interesting to note the furlex drum, and that you had to raise it. My drum is also set quite low and is the main problem I face with a self stow system.
