Which Force Required for Winch at Mast Raising Pole?

I´m going to change the mast raising system of my

to one with a cable winch attached to the raising pole as it is for

. Now I´m not sure about the power the winch must be able to handle. I ordered one which can pull 350kg (about 940 pounds). But with 4 kg (11 pounds) this seemed to be way to heavy to me. What are the winch-size and approximated weight of Your "home made" mast raising mechanism? Does anybody know the size of the winch of the custom made raising pole?

Call the factory and ask Mike Inmon. He has experimented with MANY!

Hi Ranier
I upgraded mine also and found that finding a wwinch small enough was a problem
I also came up with a 350kg winch which is way too big.
I think the M size that I have seen was around the 150kg
It is not a heavy mast and does not take much effort

I used a 1000lb winch or about 450Kg winch when I converted my X original mast raising system to the M type. I choose it because it mainly because had the most reliable direction switching cog mechanism. Some of the winches I looked at had very poor functioning of the reversing mechanism. The tension in the raising system is a function of the geometry created by the mast attach point. I use the jib halyard as my attach point. The farther up the mast you attach the more leverage and lower the tension.

The mast raising kit that I have on my

, has a very small winch (not sure of the capacity). It is a brake winch. No cog mechanisim, just turn one way, or the other. Works very well and easy to crank. I have been using it solo, with a totally useless right shoulder, no problem. It is the mast rasing pole for the

The entire kit is available from
Blue Water Yachts for US $135 +shipping. Part number 3418-1M0. Includes baby stays, pole mast bail, etc. They might sell just the winch, but it is not listed in their catalog.

You are absolutely right, that is making sense however is this the whole truth? How about the length of the pole and the position of the roll at that
IMO when the mast is in the up position the wire/rope between mast and raising pole should be about horizontally (if not on a sloped ramp

) or slightly sloped down toward the mast. Good guess?
Thank You all for the helpfull responses. Up to now the smallest at a reasonable price I made out was a trailer winch with a pull of 270kg. A new question now came up, what is to be preferred between mast and winch, wire or rope?

On the

system it is a rope/line...about 1/2" I think. The baby stays are 3/16" wire cable.

When using the M system on my X, there is a fixed length of line from the pole to a forward cleat. This fixes the pole at a 45 degree angle forward. The line from the winch attaches to the mast where the bay stays are fixed. turning the winch handle brings the mast toward the mast raising pole and the pole never moves. A little extra tension on the winch allows the forestay with roller furler attached, to be pinned to the forward chain plate/tang with no problem. Very easy to use solo, even when I only have one good arm.

I'd say that the bwy price $ for the kit is most likely the cheapest way to go considering you get all equipment needed just depends "their's that word again" how much it will cost to ship Germany

You could go to their
Parts Catalog and follow the instructions. I have done this in the past and it is an exercise in patience. In the end, you have to deal with them on the phone, or by email for payment. I think it will be easier for you to just email your request to
[email protected] and be done with it. Describe what it is that you want and that you want to mount it on a 26X. Good luck.
