Adding a bow thruster to 42 GB twin screw. Reading up on this the experts advise a larger tunnely unit - like 10" and 130+ KgF thrust - if you use a joystick. This is because people tend to overheat the thruster with a joystick control. Also, because of electrical efficiency, the norm is to stick two 12 volt battery (24 vdc) forward with the thruster.
I don't want batteries way up in my bow, under the berth deck. Perhaps I should use a more typical 95 KgF thruster, 8" tunnel, and forego the joystick control.
What do you experienced people advise on running cables from my house bank battery 12 vdc and a transformer to get 24 vdc?
Is the joystick unnecessary?
