Lots of guys at CX live on boats but it is not really a cheaper option. You get more space for the money but have a boat to upkeep. You would not be allowed to live in a camper in HKG, water? Sewage? Elec? Again don't think you have thought it through or researched it.
Your Indian and got several scholarships to go to ER for a flying course. That is a good effort, I have a friend who is just starting to look for the way forward into a career in aviation. Could you give me the details of these scholarships so I can pass the info onto him and he can try to get some financial support.
Thanks.
