Mario Celegin is seeing increasing interest in hybrid patrol knots. Integrated diesel drive engines will act to replenish boats. There’s a lot of reasons why: near-silent patrolling in batteries, and electric motor boost will enhance upper end electric mode, emissions-free operation in and out of har- speed performance.
