[C320-list] FW: Outhaul lost in boom (drawing)

[jpmesa at aol.com]

In the new sail magazine there is a nice drawing of inside the boom (reefing article) of the double block purchase system that where installed in the older boats (I think). John Holokai   #112

Irv,
I see the 3:1 double block purchase system.  I'm assuming that there is a
endant that runs from block 1 to the boom end and then to the clew car on
he boom track.  Agree?
So this means that we have double lines for both the first reef and the out
aul and we have three blocks in the boom. Yes?
Best,

Bruce and all,
o to
ttps://mail.google.com/mail/?shva=1#inbox/1293f20e5e10f0cb
nd look at page 13
Th#2 block is fixed where the boom meets the mast.
he Beckett of the #1 block has a line attached that exits the end of the
oom and we use that as the outhaul.
If you look through the C320 website and I think the manu, it showed another
ind of floating block that was a piece of metal with a pulley on each end.
This was a scheme using that double pulley for a single line (Jiffy )
eefing system where the reefing line to the luff reefing cringle went thru
ne  pulley. Then another line that terminated at the end of the boom went
hru the second pully back to the end of the boom up to the leech reefing
ringle. So that when the reefing line from the cockpit is pulled , it also
ulled the luff and leech reefing lines at one time.
 think that scheme has been discontinued and from reading the list over the
ears, most have removed that pully.
n 2001 #851 there was a two line reefing system, where the hook for the
uff cringle could also be used as a cunningham pull down went to a
tarboard side line holder. From the port side a boom straight thru line
ent to the leech cringle.
Hope this may clarify whats in the boom of the C320's

 You got my curiosity going.  On our association web site in the manual
 there
 is a drawing showing the reeving for a single line mainsail reef number
 one.
 It shows that there are two separate lines in the boom and their lengths
 are
 provided on the drawing for standing and running rigging lengths.
 Unfortunately I was not able to find any drawings or discussion on the
 outhaul anywhere.  So I guess I don't know how 671's out haul is reeved.

 Bruce,
 I am not confusing the 3:1 purchase block for the outhaul with the the
 double sheave block that was used for jiffy reefing on some boats..
 #851 does not have that jiffy reefing block.
