Decided to make a simple pair of mooring whips (similar to dock sticks), using easy to obtain materials:
(2) 3/4" x 18" Schedule 80 PVC pipe
(2) 3/8" x 48" bungee cords with hook ends
(4) 1" rubber chair leg tips/protectors
(2) 1" x 18" foam pipe insulation
Total cost was about $10 for materials.
I cut the pvc pipes to length, then used an X-acto to chamfer the inside edges.
Also cut holes in the rubber chair leg tips with the knife.
Insert one chair tip over the doubled-up bungee, slide the bungee through the PVC pipe, and through the other chair tip. Done!
I added a couple pieces of foam pipe insulation, thinking it will help prevent scuffing the fiberglass.
Haven't tried it out yet, but seems pretty easy to deploy and stow!
Note: I'd go with longer bungees, maybe 54" if available.
