Computer for boat
Sorry this topic has been discussed in many forms before.
I need a computer for the boat which I am going to buy ( 45 to 50 ft cruising sailboat). I initially considered a desktop but was scared off by the power consumption. Now I am considering a Laptop. I want to use it to run navigation and other boat soft ware, but I also want to use it for e-mails and for web surfing when I have access and also to watch DVD's and CD's, so I feel I need a Pentium 4 with Windows XP. There is a bewildering choice of brands. One way to narrow the choice is again power consumption from the house batteries since the computer will be on a lot. I can get an inverter and then plug in the power supply to that. But that route looses about 20% of the power. The better option is to have a DC to DC converter like one that is used to connect a Laptop to the cigarette lighter in a car. But how much power does that consume? Third choice, is there a brand of Laptop eg Toshiba or others which accepts power stratight from the House battery, ie a voltage anywhere between 10 and 15 volts? |
