[C320-list] boom problems

[Chris Descher]

While looking at the owners' manual yesterday, I realized that I probably
have a problem with the blocks on the inside of the boom, too.  I was
referring to the one at the end of the boom.  If something's not missing or
broken, I don't see how it ever could have worked.

Chris,

There are sheaves at the end of the boom and then there is a floating double
sheave in the middle of the boom that the reefing lines go around. The
sheaves at the end of the boom, maybe the axles need to be blocked to stop
from sliding.The floating sheave in the middle of the boom, you have to make
sure the reefing lines are going through that.  If they are not, you need to
use something like an electrician's fishing tape to rethread this middle
block.  This is what I had to do when I reassembled my boat after purchase.
