[C320-list] Reefing Block inside boom

[drshoffner at aol.com]

Bill,

The pulley system inside the boom does nothing but add friction to the system while adding little if any mechanical advantage.  The block in my boom was very low tech with the sheave just running on a pin without any type of bearing involved. The best solution is to remove the block and run each line straight through.  I did this as well as running the line through small blocks attached to the cringles rather than throough the cringle itself, and the force now required to reef the sail is about 20% of what it was previously.  There are pictures of this set up on the web site, though I don't have the exact address.

Bill:
One way to check to see if the other reef has the block inside the boom
s to see if there is a knot protruding at the aft end of the boom.  As I
ecall, the line was knotted at the end of the boom, then extended to the
lock and then up to the reefing cringle and back down to the boom it
elf.  Another way would be with the sail flaked on the boom, pull on the
eef line at one end of the boom and see if you get the same amount of
ravel in the line at the other end.

 I used an electrician's snake sucessfully yesterday to feed my first

 line through the boom. I pulled the internal pulley inside the boom 
 out the
 back end of the boom, looped the line through it and snaked it back 
 to the
 mast end. Mission accomplished, my first reefing line works.
 
 What I can't figure out is whether the second reefing line is set up 
 the
 same way with an double pulley block inside the boom.  It does not 
 appear so
 as reefing to the second point requires much more force to pull the 
 sail
 down.  If this is not the case, it seems that it might be a good 
 idea, if
 there is enough room inside the boom for both pulley blocks.  Has 
 anyone set
 up their second reef point like that?
