The only fishing I´ve done is trolling, no beach fishing.
However...one of my friends on the last trip did some shore fishing at night time beneath Martins shack.
He had an Ambassadeur, 12 feet rod and the line was special imported from USA, Martin used a coconut and a handline! Guess who caught any fish!?
Martin can probably provide you with lots of advice on shore fishing, he told me that he goes fishing everyday during the monsoon, and as I understood it it is mostly from the cliffs on Sinqerim end.
You will meet Martin and family before me, i´m going again in march.
Say hi from Chris in Sweden!
