What Should You Do to Deter Sea Lions?

Sea Lion 1

Sea lions like to make themselves at home aboard vessels and docks in the harbor. However, there are rules in place that require boat and dock owners to install deterrent measures to prevent sea lions from getting aboard.

All mooring and dock owners must frequently check to make sure their deterrent measures are in place, effectively preventing sea lions from boarding.

Below, you will find some information and resources regarding sea lions and deterrent methods:
