Re: Questions I have been asked.

I bought my Acer laptop in the US 2008 it pact in December 2013. On the out side the only damage visible was rust on the USB ports. When I pulled it apart to get the hard drive it looked pristine. The hard drive is still going strong in a USB external case. My new laptop is an acer and I never pay more than $400.

As others have suggested, a fanless mobile PC with SSD drive is the ticket for this.

But even better is a laptop with docking station and external monitor and keyboard. You can take it off the boat with you when you're not on board, reducing salt air exposure. This is what I do, FWIW.

We also sprayed everything metal in the engine compartment. Not a single spot of corrosion in a total of 3yrs cruising in salt water.

Awesome!!! Just what I'm looking for! Thanks!

How often do you need to reapply?

We did it before each trip south from the Great Lakes, not sure that was necessary. When you spray it on it becomes a wax like film, it actually feels like you are touching a wax candle. it probably lasts for years.

Re: Questions I have been asked.

Here in central Florida laptops are on almost every boat in marinas these days. I've only seen one 12 volt desktop PC on a boat and that was an old Prout Snowgoose 37' catamaran which had the room for it.

I recommend a Laptop as I've seen them get wet ( had to turn it sideways to pour the water out of it) and you just dry them out and they fire back up again. If they don't a couple of hundred buys it's replacement. If you just use a computer for email and internet, buy a tablet instead.

I'm surprised this is an actual discussion these days.

Re: Questions I have been asked.

Never had much problem with a laptop on a boat other than batteries. Desktop..hmm ask your buddy...why?

Best thing we did was get a solid state hard drive. The gyroscopic precession of a rolling boat on a spinning disk is a death sentence.
