Spot on.
Unfortunately. most fishermen cannot afford such luxuries. They are living hand to mouth.
Even donating life vests to them would not help. They would probably sell them for cash at the local market.
This has happened to me twice when I have tried to help people.
Bought all staff motorbike helmets. One week later - all but one were sold.
Working for a charity, we bought mosquito nets for a few villages. Again, all sold.
