I still think the club is involved,because its only members can fish the piers
and as such the club enforces the rules and the members are covered by club insurance(included in part of the subs).
If the worst had happened the club and the offender would be liable,so as a near miss it should be investigated so not to be repeated again.This person that did this needs to be spoken to by club officials
Well that's my take on it.
Rules state.............no dangerous casting...... so no pendulum casting is not banned but if any cast is deemed to be dangerous then the club steward can request angler to stop this practice.
Had a look John nothing seen M4.
