Checking the rigging of my P16 for deviations from the manual (there were some), I noticed a section in the jib rigging area titled "Jib Sheet and Jam preventer". Needless to say, my boat does not have one of those.
What's worse, I am not at all clear on how to rig it. The manual says take a 7' piece of shock cord, "attach center to the mast and tie each end to the dolphin striker bar on either side of the mast". Where should it attach to the mast so that it does not slide down to the base and become useless? No specifics are given and the picture is completely useless. Similarly, how would I tie it to the dolphin striker bar that it would stay at the sides and keep jib lines from getting caught under the mast rather than slide down to the center of the dolphin striker bar and again become useless?
π Any suggestions much appreciated.
Like an upside-down "V". At the mast the shock cord can go through the diamond wires (lower end).
Diamond wires? What's that? Not sure P16 has it. And still, when jib sheet is pushing down on it while it is trying to get itself jammed under the mast, won't the low end of the inverted V slide all the way down to the center of the dolphin striker bar and let the jib sheet get jammed?
run a bungee from bridle wires connecting shackle to mast just above mast base, make sure your jib lines sweep above bungee, this will stop line from wedging under mast. some sailors use a line/bungee forming an inverted "V" in front of the mast, goes from beam up to bottom of diamond wires back down to opposite side beam.

p15 and p16 do not have diamond wires
Diamond wires are steel cables that run up the sides of the mast. they are needed on larger masts to help prevent catastrophic failure of the mast and to give the mast prebend (to optimize sail shape)

You can put an eye strap on the mast. The jamming doesn't happen under tension, so it shouldn't slide on the dolphin striker. A clove hitch knot will do. The jamming occurs when the jib sheets touch the mast on each turn. If you wait until the jib is backwinded before changing sheets, chances of jamming are less, as the jib will go quickly to the other side. That will also help with tacking if you have troubles with that. It won't help win regattas though

Wow.
Use a 7 foot long piece of 1/4" bungee.
Stand in front of the mast and wrap the middle of the bungee around the mast above the boom gooseneck so that the ends cross in front of the mast.
Tie the ends to the dolphin striker on each side, making sure they go underneath the jib sheets as they go to the jib, and slide the bungee ends outboard as far as they can go.
You should now have an upside down V of bungee that will keep the jib lines above and off the mast base and other stuff on the front beam.
Could someone post a photo of what this looks like when completed correctly?

Click on the image to enlarge and you can see a jib sheet preventer. So easy a caveman can do it . . .

here the line (bungee) is attached to my bridal under my furler (i had a shackle there for rigging a spin)
here you can see the see a bungee tied to my bridal that then is tied to my mast
