I use my boom vang
On my Hunter 31, using a snap shackle, I disconnect my boom vang from the base of the mast and attach it to the toe rail, then tighten it as needed.

It can be simple or complex
The main purpose of a jibe preventer is to prevent an accidental jibe during a run when an accidental jibe could cause injury to crewmembers or damage your sailboat. The simplest jibe preventer is a line attached to the end of the boom using a bowline knot and run forward to the bow cleat and looped back to the cockpit. If you are running "Wing on Wing" with the boom off your starboard side. The preventer line on the starboard side is attached to the end of the boom using a bowline knot, the other end runs forward to the bow cleat and loops through the bow cleat and down the port side to the port wench not being used. The main sheet and the preventer line (or is it a sheet?) are adjusted using the wenches to lock it place and prevent an accidental jibe. When you want to move the boom to the port side during a run, you let out the preventer line as you pull in the main sheet and jibe. When your boom is on the port side, you tie a bowline on the preventer line on the port side and attached it to the end of the boom and use the starboard preventer line on the starboard wench. As Bob stated in his response, you could use your non-rigid boom vang as a jibe preventer. Or you can also buy a boom brake from Dutchman and attach it to your boom. The boom brake controls the speed that the boom will swing as it moves from one side of the sailboat to the other. The boom brake has three gears, which uses friction to control the speed at which the boom will move from one side to the other. This is the most expensive way to prevent an accidental jibe.

Pretty clever
You inspire a variation. A line that runs from boom to forward portside cleat, then to forward starboardside cleat and back to same point on boom as originally connected. Now two shorter lines bowlined into the loop line about half way between the boom and the forward cleats, one each side. To secure preventer, winch down opposite short line. whaddaya think?

I’ve never seen it done that way.
You could try it and see if it works. For a jibe preventer to work, it must exert a force on the bow side of the boom. When you are pulling on your big loop, you are also exerting a force on the stern side of the boom, since its one big loop, some of the force you are exerting is not being used effectively. If you want to avoid the need to remove and re-attach the jibe preventer when you jibe, than another variation would be to use an "M" style jibe preventer configuration. An "M" style jibe preventer looks like a big "M", it uses two short lines, instead of one long line. The "M" style preventer can be made even shorter by using the toerails closer to the mast and connecting to the boom vang attachment point on the boom. Your mooring cleats and chainplates can withstand a lot more force than your toerail, but on smaller sailboats where the force generated by the wind on the mainsail is manageable, you could use the toerail instead of your bow cleats. On a San Juan 23 owner’s website, he showed a diagram on how he did it. Fair Wind. Clyde

Ditto on the boom vang
No muss no fuss ... Safe, particularly with green crew. And I am usually jibing my gennaker at the same time. *I*, or the crew member I send to midships, just has to loosen the cam on the vang a bit, undo the snap shackle, and *I*, or someone else in the cockpit centers the main while we jibe, and then reattach the vang. Simple, safe and efficient. [And I am lazy! Don't want to deal with extraneous strings
