    Hi.

    I am new to the world of yachts. I am interested in "Hybrid Yachts". Hopefully in the 60' to 70' size. But the only one I found in that range was the Greenline brand. Are there any other hybrid yachts out there that are not catamarans or super yachts? I want to be able to cruise long distances without burning too much fuel. and I am not interested in Sailboats.

    Thanks

    LOLOLOL, well Catamaran hulls are very efficient for that speed. Your best bet would be to just get a traditional long range displacement hulled trawler.

    Thanks Capt J. But do trawlers burn less fuel than a flybridge cruiser?

    Typically, yes.

    Typically a little less. However, if you ran a FB cruiser at 8 knots you'd get almost the same mileage. You would have to run at cruise 30 minutes every 6 hours to clean things out.

    The answer depends on why you're interested in hybrid yachts and what you want to do with the boat.

    If you're just trying to save fuel, just go slower, as Capt J says (essentially). There are other benefits to hybrids, assuming the Greenline-like powertrain of diesel engine-->generator/e motor-->marine gear-->propshaft ...coupled with large batteries and inverter(s) and no generator fitted. I like...
    Silent, smokeless docking and departure - easier for the crew to hear each other and not waking an entire anchorage at 4am.
    Hours of 120v/220v without running a generator - e.g. A/C all night at anchor
    A twin screw boat with only two internal combustion engines, yet twin generators

    I'm sure there are more, but you get the idea.

    I don't see hybrid as a fuel saver except maybe as a short trip dock-and-dine/sandbar boat behind your house that you use mostly in electric mode.

    We may never see the expense of a hybrid system pay for itself in the original purchasers lifetime.
    Generators will have to run. Shore side grids can not recharge a yacht cheaply.
    Electric cars can not be supported by our outdated power grids already.
    Diesel will out live us.

    Capt Ralph - A few thoughts regarding your comments...

    1. Perhaps not, but as I mentioned, the benefits are boating pleasure first, IMHO.
    2a. Sort of, but not standalone, and avoidable for long periods of time, or non-existent while motoring under diesel power.
    2b. Hybrid doesn't depend on shore power, you're thinking of plug-in electric boats, which are NOT hybrids.
    3. I'm hoping they're working on power grids...
    4. Hybrids use diesel. (except sailboats with electric propulsion)
    5. No need to panic.

    One other benefit, btw, is that if you have a fuel issue, you still have some propulsion available. Limited but greater than zero.

    Of course any propulsion system has to be wrapped up in a package that is otherwise desirable to boat buyers.

    Check Hugh Elkaims article on wing sails 'Catalyst' autonomous sailing vessel there are many wings based on his design being developed now. Perhaps a good compromise.

    Don't we all......

    The laws of physics always apply. The only vessels that have achieved what you want used solar, were very lightly built and the skeleton crew had a personal luggage allowance of 2.6 pounds. And oh, it was a catamaran because.... physics.
