Have not been able to find any specifications on it as yet as to size, power requirements as yet but joined this group just this morning and am wading through this material over the course of the day. Interesting concept though over conventional prop/shaft propulsion if I could just find out if it would fit on a 26 foot (8M) boat?!

On the other hand the European boat clubs are almost exclusively powerboats and ferries. There are hundreds of daily use electric ferries in active use in europe the european boat clubs would have a lot more experience with ferry question then any answers you will get here. But feel free to ask questions.

The motors drive the propeller through a long shaft (as longtail boat, commonly use in Thailand). We plan to sail from Bangkok to the most south of Thailand for 700 km distance (with 4 passengers). The boat will then operate in Tarutao NP for multipurpose use but maintly to show the ecofriendly boat.
