I even blew the lights in my laptop screen with a 12-19v inverter! So would suggest great caution with laptop. I think I would charge the boat battery then plug in a 240v inverter then the laptop 240 volt charger. I think noise levels are quoted at a specific distance often different makers use different distance. The decibel Db figures may be unweighted (higher number typically 91 Db @7m ) or "A weighted" (lower number reflecting human audio perception typically 60Db @7m)
