what are the procedures of raising the mast on a 1971 T 27 in order to replace the mast step. It has ratted out and needs to be replaced. Also what is a good material and the dimensions on the block.
I'm not sure if you've proceeded yet or not, but the mast on this boat will be big/heavy enough to use a crane. Most boat yards will have done this countless times. The shrouds and stays will need to be marked so when you re-install the mast, you can tension it the same. I will use electric tape on the stud threads right where they enter the turnbuckle. A black Sharpie marker can work too. The next thing is the electrical connections, make sure they are labled! Other than that, it's not too difficult.....The crane does the heavy stuff. Don't attempt to do this mast manually....gravity is a b_tch!!!!
We pulled the mast on our 1967 Tartan 27' (#328) this past fall using our clubs mast pulling crane. The crane top is above the spreaders and has like a 6:1 purchase. It took 4 guys to move the mast to where it is still sitting once plucked from the boat. Previously I have had the boatyard use a crane to pull the mast.
This past fall we found soil (rotted wood) at the mast step and will also be rebuilding the step. I am also not sure of the original dimensions of the mast step but I am thinking about using Ipe or Ironwood to make a replacement step. One problem is that if the new mast foot is too high (too large) then the existing shrouds and stays may not fit or at least the turnbuckles will need to be totally reset.
Have you joined the T27Owners group we have going over on Yahoo? Someone over there may have been there and done this and knows the height and size of the mast step.
i lifted the mast this past November on my t-29 with a portable manlift (the one I rented was towable) I recommend 3 people for this job, especially if you have a roller furling.
basically you need to lift it under the spreaders and slowly lower it to the ground. the 3rd person is for stabilizing and spotting during the lift. it will drop the time required by 1/3. It was my first time and it took 4 hours for my dad and I to get it to the ground, wrap it up with carpet to prepare it for transport, and then mount it on the deck horizontally.
the lift was easy to operate.
if your boat is still in the water, then perhaps one of your neighbors in the marina can show you the ropes for un-stepping your mast. Up here everyone steps their masts in the autumn and pulls their boats up onto the hard for winter storage.
I appreciate the info. Sorta what I thought, but I may have to have it hauled and let the yard do that. It seems to be more expensive here in Charleston to get anything domne at a yard. No owner projects..
