I am in the process of purchasing a Beneteau 393, and I am confused by the lack of details on what each option includes. Perhaps you have purchased this option and can tell me more about it, or perhaps there is a resource I cannot find that gives details on :1. "Inverter" Which manufacturer, Model #, output, sine or square wave ?2. "Geneker Gear" What does this include, a port side winch maybe ?3. Air Conditioner. What manufacturer, Model #Also, I am also curious if the grounding system that comes with the boat needs to be improved, or if it is beefy enough to protect from lightning, protects people in the water around the boat, etc ?
