Alexander,

Jose Venegas of Ipanema SM2000 Hull #278 posted his bowthruster power consumption data here:  https://amelyachtowners.groups.io/g/main/message/63102

The peak current draw was about 450A and the voltage at the time a little over 26V which makes the peak power draw ~11,700W.

Amel did not fuse the large battery cables going to the bowthruster but several members have since installed fuses.

Read the entire thread for a good discussion on this topic.
