- HENK GRUNSTRA - The costs of an electric ferry operation are impossible to defi ne due to all the
variables already discussed above. However, there is often a case to be made that,
although initial capital outlay can be considerable relative to a conventional ferry
operation, the operating expense can be signifi cantly lower over the lifetime of
the vessel.
