The suspended Zinc “fish” is BONDED (not grounded).
Clipping it to the shrouds or railing will only work if the shrouds are also connected to the Bonding system.
You shouldn’t require these supplemental zincs, unless you are experiencing rapid zinc loss (½ eroded in less than about 12 months).
In any case, suspending the extra zinc in close proximity to the metals (or mounted anodes) that you wish to protect, will increase efficacy.
