I don't have any pictures of the reefing handy (other than those posted previously) so I will attempt to describe.
1: Clew - The clew setup is exactly the same as the standard except that when the line exits the boom at the mast
end it is lead to a block on the collar on the mast
and back to the clutches/winches (note - 4 additional clutches reqd).
2: Tack - Standard set up : There are 2 s/s lugs on the mast on each side. These are used to attach the standard reefing pennant (webbing strap). Looped through the port side and on the starboard there it a snap shackel attached to the lug to connect the loose end of the pennant.
So - Remove the snap shackels from the stbd side of the mast but leave the shackle on the lug. Fasten the end of the new reefing line to the port side lug on the mast. Feed the line through the reefing eye in the luff of the sail (similarly to the way the clew line is fed.) Then feed the line through the shackle attached to the stbd lug, down to a new block attached to the mast collar and back to the clutch
bank. The shackle is just bringing the line back to the same angle (of pull) as the port side and does not have much load on it.
Obviously the respective top/bottom pairs of lugs are used for 2nd/first reefs
You could have a sailmaker
fit a block to the sail at the reefing point (as recommended by some people) and at the lug on the mast to reduce friction but It works fine as is and is the lowest cost/impact solution.
Note that you can still use the old webbing reefing straps and boom end jammers in a emergency
, especially if you leave the snapshackles rigged (I have not).
I have used a double block at the mast for each set of tack lines and clew lines as there are limited holes in the mast collar. You only ever have tension in one at a time.
The pictures I posted previously show the mast and clutch
arrangement but don't go up as far as the eye in the sail but that is very straightforward.
I hope that helps.
