Yup! That is what I am up to for my I-28. It looks simple enough. I have the tabernacle scale mockup ready to take to the fabricator. The boat is stored adjacent to the fabricator's and they think it a great idea! Ha! They have offered to hand carry the mast across the lot and weld on the cheek plates on for me. They want to see it work. Me too! I am a little anxious about doing it the first time but what can go wrong if I measure everything correctly and follow Ed's instructions. If things go as planned the "first time" will be a stepping. We will lift the mast onto the boat and start with it down. I am designing a crutch to support the bow rail and the mast when it gets lowered (and raised). I don't have the bow pulpit "extension the Nor'd Sea 27 does so the weight distribution I need to plan for is a concern. I am working on a roller that will make bringing the mast aft easier. Perhaps a roller that captures the base, too. When you remove the pin at the tabernacle, what kind of upward force do you experience at the base of your mast while it is sitting on the bow rail? I am expecting to have to "capture" the base of mine. Calculations next. I should be able to build a simple aluminum crutch with a couple of struts intersecting the bow rail and extending a couple of feet forward and a little higher. I like the idea of carrying it a bit higher than you do.
Thanks for the videos. How did you get the boat back on the trailer?
When you get down to it, it is simple. Like a LOT of the jobs I learned on our boat, the work up to it, metal & physical, is harder than the job itself. At least it seems that way to me.
Our mast does not have a foot welded to it. The mast step on deck has an elongated hole on each side in it for the bolt. As the mast goes forward, the loosened bolt slides up a bit in the mount. The forward bottom of the mast also has a rounded area to it. One thing that we have to watch out for is that once the mast is lowered, (or as you prep for raising) is that as it's base is ready for the bolt to go in, the top of the mast is far forward and tends to drop, so I have to hold the base down. Sit on it and then put the bolt through the sides of the mount and the mast base.
I made a board that fits across our bow pulpit with a large trailer roller in it. Once the mast is down sitting on it' it's easy to just allow the base to rise up a bit (under control) and roll it back. I then support it on the bow pulpit (without the roller) forward, on the boom gallows aft and I use one of the wood 4x4s trailer chucks, that I special cut to to mount where the mast step is and it supports the middle of the mast for transport.
As chicken as I am, I had the mast raised for me the first time to make sure everything fits and is secure. Lowering is then easy and setting up the 4 part bridal is easy, and if not taken apart, the correct size for the raising.
If you need any close up photos, just ask and the next time I go to the boat I will snap a couple.
