Attaching fairleads to mast boot

[patrscoe]

One of my projects (one of many...) is running my outhaul, main halyard and reefing lines aft. I have just started this project and figuring out the best way to attached the fairleads / blocks to the bottom of the mast.

I don't want to haulout the sailboat, step the mast and install a mast plate as it is costly to haulout, relaunch and step the mast.

I don't want to penetrate the cabin deck. Less penetrations, less likely it will leak overtime, also I don't want to put any additional stress on the cabin deck.

I have a steel (I believe it is cast iron or similar) mast boot that is mounted on the deck cabin. It is approximately 2" high. I would like to install pad eyes to the boot, install fairleads/blocks to the eyes so that the lines can run down from the mast to the bottom fairleads then head to a deck organizer, etc... to aft. I would like to avoid attaching pad eyes to the mast.

Any thoughts or previous experience?

your boot is the mast step!! suprized it is made out of steel. you should be able to get mast collars for what you want to do, that clamp to base of mast and or are made to be attached to mast. these collars have multiple holes are perimeter for block attachment

Miss used words. My mast is supported by my cabin deck and there is the original mast collar where the mast sets on. It is metal and has a flange that is attached to the cabin deck.
I have seen mast collars that have attachments for blocks and fairleads but they all require stepping the mast and they either go under the original collar or it's a replacement.

Wrapping a custom made collar around will work. Just need to figure out how to do it and ensure that it is strong enough. I will be running my main halyard, outhaul and two reefing lines back. Unfortunately, all on one side due to certain reasons.

I would figure 1/8th or 3/16th inch material would work because you would be getting a diagonal pull. I would use a full rap collar with a flange welded where you need it with a appropriate holes. just walk around the marinas there has to be something similar to what you want/need. I would use S.S. and put polyethylene film between it and mast, or a rubber band under it to stop or slow corrosion with dis-similar metals. you need to figure what the pull will be with all lines under lode and in extreme conditions. naval architect or engineer should be able to help

And it has to be attached to the mast, either with rivets, self tappers, or best machine screws in threaded holes to keep it in place.
