If you don't detach your shrouds on one side before you begin to lower the mast you will definitely bend/break something. Chainplates in my case.
You can attach a ratchet block to your jib tack tang and run the spinnaker halyard through it. This is a great way to help lower and lift the mast.
Lowering to the back of the boats is definitely best.
:: Javier,
::
:: How to unstep and step the mast? Carefully :-)
::
:: Since this my first boat and first time of doing this
:: ourselves, take my opinons with a large dose of salt.
::
:: While I think it's possible to do it with two people
:: (with an intelligent arrangement and use of supporting
:: lines), having done the whole thing now, I think it's
:: best to have 3 to 4 people to work together.
::
:: Before you attempt to unstep/step the mast, make sure
:: there is plenty of slack in the shrouds. At the risk of
:: embarrassing myself in public, i actually damaged the
:: mast butt when I tried to unstep/tilt the mast w/o
:: creating enough slack in the shrouds -- that oversight
:: translates into a $250 welding repair job at Anderson's
:: to fix the cracked mast butt. BTW, a new mast will
:: probably run $3k to $4k according to Seal. Certainly
:: worth more than our boat.
::
:: The mast step is nothing but a short extrusion that the
:: mast fits over -- the image at this link is a pretty
:: good representation:
::
:: http://www.apsltd.com/images/gallery/10064-1.jpg
::
:: The fit between the mast over the mast step is not
:: super-tight. That is why you can unstep the mast by
:: tilting it down. Had it been super-tight, I guess you
:: need to pull the mast up straight to get it off the mast
:: step first lest you damage it when tilting the mast.
::
:: We tilted the mast forward when we unstepped it. As the
:: mast tilts, you actually need more slack in the shrouds.
:: I think if I were to do it again, I would detach one of
:: the shrouds and have one person use a spare halyard to
:: keep enough tension from the detached shroud side to
:: keep the mast from falling towards the other side where
:: the shroud is slackened but still attached.
::
:: The turnbuckles on our old shrouds were rusted frozen,
:: so we actually had to detach the shrouds from the
:: chainplates and uses a short line to tie the bottom of
:: each shroud back to the chainplate temporarily
:: (remember, there were only two of us). I wanted the
:: shrouds still attached to prevent the mast from falling
:: sideways to either side as we lowered it. Again, in hind
:: sight, more hands could've helped (and possibly
:: prevented the aforementioned mast butt damage).
::
:: We led the main halyard to the stern and my partner kept
:: a tension on it and gradually let it out as we tilted
:: the mast forward. Now Lesson #2: I was on the bow to
:: 'receive' the mast as it is lowered down; when I finally
:: got a hold on it, my partner slacken her tension on the
:: main halyard even more to lower it completely. At that
:: point the base of mast pops up , because the place I was
:: holding on the mast is to aft of the pivot point of the
:: mast. Fortunately I quickly lowered the mast down and
:: laid it on top of the deck, so it wasn't too much a
:: problem
::
:: I talked to Steve Seal later (I got the new mast step
:: and mast plate from him). He recommended that the mast
:: should be tilted towards the stern. The reason is that
:: the distance between the mast step to the stern is
:: slightly longer than that between the bow and the mast
:: step. You can get to the 'correct' side of the pivot pt
:: of the mast easier from the stern.
::
:: We were going to raise the mast by ourselves, but on
:: that day another S22 owner a few slips from us was
:: around. He helped us stepped the mast. We did it from
:: the stern this time.
::
:: We got the new standing rigging and new spreaders from
:: Svendsen's. My boat partner heard good things about
:: Svendsen's from one of her S22 friends. I got the mast
:: plate and mast step from Seal. Seal definitely is very
:: knowledgable and willing to share info with you (when
:: you buy stuff from him). It's hard to get a hold of him
:: sometimes since he is a one-man shop.
::
:: good luck
::
:: Pei
::
::
::
:: :: Pei,
::
:: :: I plan on swapping out the standing rigging soon also.
:: :: Did you unstep and restep the mast yourself? If so, can
:: :: you tell me how you did it? Also, where did you get your
:: :: rigging made up?
::
:: :: Thanks
::
:: :: Javier
:: ::
:: :: :: Just finished replacing the standing rigging on our Tuna
:: :: :: (1970, #523). Now it's time to get a new set of sails.
:: :: ::
:: :: :: I did a bit of research -- it appears a new sail
:: :: :: (doesn't matter it's a main, jib, or genoa) will cost
:: :: :: about $600-$700. Ka-ching!
:: :: ::
:: :: :: Any thoughts on acquiring new (or used) sails for S22?
:: :: ::
:: :: :: thx

:: :: :: Pei
