If you fellows ever get a chance to experience an electric motor driven vessel, give it a try. You will be amazed at the significant torque at the low end and the instantaneous forward to reverse capabilities without the need of a gearbox.

If I were repowering one of these older motorsailers, I would definitely look at the new diesel/electric technologies that can eliminate one or two extra aux-generator units and allow for electric motor drive of the props without the need for gearboxes


I talk about some of those subjects, and reference some other websites here under my new motorsailer design
