Thank you for your answers, it is a continuous topic as you have mentioned, I trust the answers on YF

The power consumption at anchor is mostly the big fridge, water pump and lights at night. It is a 47 footer sailboat.
At cruise, the autopilot and the 8hp bow thruster come into play however the engine runs mostly at the same time.
