A navigation system using a laptop although cheaper then dedicated systems have two problems.
1. A laptop uses considerable more power, so get a machine that is efficient as possible.
2. Most laptops use Windows. Nuff said.
At maximum you would want a 100 amp alternator. 80 amps would be better considering the size of your engine. Make sure it is a proper marine alternator and not a marinized automotive one. Also a smart 3 stage regulator is a must.
