How to attach shock cord to pseudo spongex bouys?

EFW

Paid $9 a bouy w/free shipping. They are 5" across so a little small but before I run down to the hardware store and rig something to attach the bungee do you guys have a tried and true method? (nothing but a hollow center hole top to bottom)
Thanks

This method works well:

Buoy ties

Zman

When I used this type of buoy we would fid a loop on the end of a short piece of poly rope, slide the loop about 3 inches into the hole in the bottom of the buoy, then push a galvanized heavy nail through the spongex and throup the loop. Use a nail not long enough to stick out the other side when the head is pushed flush. Quick n simple.

Like @Zman says... galv nail through the bottom, but we go through a short link of chain.

We used PVC pipe caps- drill a hole, thread a rope loop through the cap, tie a large enough knot that it will stay, goop the cap up with epoxy, and push it in. The correct pipe cap will take enough effort to push in that it might stay with friction, but the epoxy keeps them in. Ours lasted for years without a failure, while the ones with nails sometimes worked loose over time.

We do what @Zman said also. Quick cheap and reliable.

looks like it might work ok.

@Bruce_Butterfield
Thanks Bruce, I was looking right at that and never even saw it

@Zman now I know what that rusty metal was sticking inside

Thanks guys preciate it. Never had these before I'll give them a try. If these start disappearing I'll go back to rubber. The Price is Right

@Nando 's idea works well, and is relatively EZ to do. Just use a PVC endcap that needs
a press fit to go in. Plus glue. I've used solvent glue.

@Edbrazil
Thanks Ed. Appreciate it.

Nando

Of course it works @Edbrazil , I learned from the master...

I also have a way of fidding up a loop of line that goes over and through the buoy, but
it is a bit time-consuming. Method needs to cut 2 notches in the buoy.

I use those style buoys for boat guides on my course.

I go to the hardware store and get 3/4" PCV and epoxy. Lather up the pipe with epoxy and slide it into the hole of the buoy. Then after it drys cut it to the desired length and drill a hole in the end of the PVC.

I hate the ones with metal in them. I always take the metal out and replace it with some PVC.

@BrennanKM, I think it's a MN technique...
