They fish with pairs of boats like this on the other side of the world in the Indian Ocean. This was drift netting, I think. The Indian method was more 'purse seine', a net between two boats was dragged towards the shore and the opening between the two boats simultaneously narrowed until they were together at the shore line. A whole village full of fishermen would then help haul the net in towards the beach and fish the catch out of it with smaller nets by the basket full. This is dangerous work. I once saw three Queensland sea snakes in one net! And they get those in the Phillipines too. One day I'll find, digitise and upload the whole Goa Calangute Beach fishing slide show from 1970.
I really liked the painting. I rarely favour works that bear the dA water mark because it often ruins them, but your work survived this imposition with nearly all of its charm intact so I simply had to favour it.
