Boats in that part of the world do have special power needs to handle the mandatory air conditioning loads. It will be interesting to follow your decision making path to boat ownership.

In your area what is the electrical volts and how many amps on the dock?
If you have enough AC electric, 50+ amp 120 volts, or 25 amps 240 volts, and the boat is not over 50 ft you should be able to have enough power for air conditioning on the boat. Might be able to get by with 30 amps 120 volts, 15 amps 240 volts.
