For a cruiser a hybrid electric system has a lot of benefits. Basically it uses the conventional diesel engine, prop, gearbox, and adds an electric motor that bolts on. So if something goes wrong, all of those parts can be serviced worldwide. The electric motor is a form of redundancy, and can also be used as a starter if the starter fails, and the diesel motor can function even if the electric motor fails. At low speeds the electric motor only is used. The electric can be used at the same time for some extra power. For short trips with shore power you can get around without using any fuel. And you can recharge while cruising with the electric motor working as an alternator, allowing you to spend most of the time on only electric, extending your range.
