Sailing in SE Asia

[worldcitizen365]

My name is Jimmy and i wanted to crew on a boat to spend some time on the sea but just can't find any, i tried nearly all the sites i can find, maybe some of you have read my post on other sites but i think i am gonna have to give up this plan if can't get anything from this website , so i really hope you guys can help me, i will be arriving in SE asia around Feb or maybe early March in 2011 and i wiil be traveling in Thailand , malaysia and indonesia, i have a about 6 months so i can do pretty much anything and i don't really have a plan so i can go anywhere at anytime but i JUST CAN"T FIND A BOAT, it 's frustrating , i was told this on a website that you can actaully go to a bar or the marina and just ask, i mean how do you even start a conversation like that or who am i suppose to talk to ?? , i am really new to this so........ , i am sorry about this long message and Thank you !!!
