Greg, if I could pull the stack pack out of the way I'd be wholeheartedly in favor. I'm probably going to have to make new lines so I can do that.
I found this photo that may help explain what I do…
On my pack, I can unhook the top 2 securements to the mast, which lets my pack drop down. Then I uncleat the line that tensions the lazy jacks. Once it is loose, I gather the 4 lazy Jack lines ( only 3 showing in this photo), starting with the aft-most line, walking towards the bow, and gathering them as I move forward. The lazy Jack line is long enough that I can collect all 4 lines and lead them parallel to the boom.
I roll the mackpack cover down to the boom level, and wrap the end of the lazy Jack line ( or a bungee or whatever) to keep it from falling on the deck. Repeat on the other side.
This gets the jacks and cover out of the way, and the loose-footed sail can have a full shape all the way down to the bottom edge.
Admittedly, I only go to the trouble of moving the Mack Pack out of the way on light wind days when I need all of the draft in the sail. If it is windy, I don’t bother.
Greg
