I work mostly with a laptop, as a portable device using mobile phone on Android (battery 4000 mah) in order to quickly respond to customers if food, for example, bike or ride a boat. Phone with very bright screen and the matte film which allows you to work even in a bright Sunny day.
There is one problem only - the actual range of tasks with the mobile phone is very limited and actually only talks with clients and planning tasks. On the implementation of tasks, the programming of the question.
In this regard, I would like to take the boat laptop to be able to relax, freelancing and it does not limit itself to the task. But any normal powerful laptop is the problem - battery lasts max 2 hours, in this regard, I want to take the boat uninterruptible power supply (plus a set of charged batteries).
But an uninterruptible power supply essentially converts voltage 12-->220 - in this connection the question arises - and not weird shock - especially if it rains or gets a spray of water (in this case laptop prepared with a sealed bag that protects the laptop from water)?
How likely is that still there is a boat if not of iron, and rubber? And how dangerous it is - because the maximum current given by the UPS is still not the one in the outlet (and much less)?
Normal laptop powerful enough for eight hours, two laptops time has passed.

I don't know what your laptop is and what his included power supply, however, the power supply personally, my laptop outputs 20 volts. What about 220V You say in your question is not clear to me.
A voltage of 20V is quite capable of delivering solar panels. I saw online where the backpacks with embedded solar panels. I think if you give them a little tweak to resolder the output or to connect an adapter, it is possible to power Your laptop. Google for the phrase "Solar charger" and buy a soldering iron.

Put the motor on the boat, and to him pick-up a Dynamo to current to develop.

The battery backup is not needed - convert from DC battery to AC 220 volts, and then inverse transform the laptop power supply. This is just extra loss of energy. Not to mention the fact that the 220 volts is dangerous on the water.
Check the voltage at the laptop power supply.
To assemble the Assembly of batteries of appropriate voltage.
Add stabilizer (sold ready-made in stores electronic components).
If you strongly fear, that can all pour and tightly sealed (battery - alone power supply separately).
If money is small - lead battery (car, motorcycle)
If you have enough money that LiFe
If money is a lot easier brand laptop spare battery (2-3 pieces needed).

If the water is home to electric eels, it is possible to recharge them!
In General, what hinders to buy a laptop with a working time of 8 hours or more? MacBook, Melkomyagkie Surveys to help you.

"any normal powerful laptop is the problem - battery lasts max 2 hours" - Macbook to help you.
When taking your, and in 2014 worked from 7 to 12 hours. Depending on the required task.
Now it is enough for 5-9 hours. But he is 2.5 years and is open every day from morning to evening.
PS current above 0.1 A is already deadly to humans.

Take a normal laptop from Apple, or get a 12V battery and 30Ач Converter with 12V to the required voltage.

If the boat covered, then you can safely take charge for a laptop on a solar panel and using it and a grief not to know)

If the author is a programmer in the boat, then spend your time on stuff he doesn't want.
Option 1 - buy powerbank for the laptop, a message their and use. The fastest.
Option 2 - make powerbank to order, for example in the workshop of electric bikes. Might be usability.

To get a bigger boat, if you like to work. That's how this guy did.
