This is an answer to Brian ,or rather another scheme I was witness to . 1968 we had just loaded about 10000 tons wheat in B C Canada ,a gift to the starving in I ndia , we docked outside Columbo ,couldnt get in ,disbute over who unloads , next thing we are told to give it to the fish ,it had got wet and was dangerous ,this was because of waiting for 7 days ,with the hatches open waiting for the barges . Needless to say the good people of B C were never told .sad innit ,and these things still happen .
