Since you're posting in English, I assume you want to know about life on English East India Company Ships. That, unfortunately, I know nothing about. What I do know, however, is a bit about life on Dutch East India Compnany ships (mostly gleaned from "De omweg van Naporra", a retelling of the diaries of a Prussian sailor on a Dutch East India Company ship in the 17th century. If that's something you're interested in, here goes:

• Ordinary sailors were poor. Captains and officers were wealthy, spent some of their own money on journeys and expected to make a profit on goods they would manage to ship back on their own accounts. Ordinary sailors, however, were drafted for journeys on what often were false pretenses (a sort of indentured servitude, if you will). There's a reason why Naporra is Prussian - the relatively wealthy Dutch wanted nothing to do with life aboard an East India bound ship.

• Even ordinary sailors expected to make a profit. They tried to bring some money along with which they could buy goods in the Indies they could sell back home.

• However, many ordinary sailors died on the journey. Disease was rampant. Malnourishment and plain old violence did the rest.

• Things did not improve once the ships arrived in Bantam and Batavia - Naporra writes about how happy he was to be able to buy rations of rice gruel in the port of Batavia - surely not a sign of wealth!

• A smart sailor could, however, save up enough money to spend on luxury goods in the indies (a not so smart sailor would have spent it on booze in the Cape of Good Hope). If he survived the journey back, he would actually end up with quite a decent sum of money to start up a life in Europe, which is exactly what Naporra did - he became a respected trader in Danzig.

• Most sailors never succeeded in the scheme outlined above, however. Lots of them never made it to the Indies and even if they did, lots of them never made it back.
