[Rhodes22-list] Chet about Mast raising question

[Hank]

-Chet,

Despite Ed's doom and gloom predictions, raising the mast from the bow
without a gin pole or anything else is not that difficult.  Once the mast is
balanced on the pulpit, it takes little force to bring it down to the
tabernacle and install the bolt.  If you do it according to Stan's
instructions, you connect the forward stays and the upper shrouds prior to
raising.  Once they are connected, you can then raise the mast and it will
not fall side to side or go past vertical.  Once it is up, connect the aft
lowers and then you can let go and connect the rest of the stays at your
leisure.

Check out Raven's 1988 owners manual at http://www.rhodes22.org/doclib/.  I
used this method with no problems what so ever and no elephants.  Just two
normal sized guys of average strength.  Like I said before, the mast crane
is great if you do it ofter and an unnecessary luxury if you don't.
