The crossing to New France was subject to all sorts of perils: weather, pirates, and illness among the crew and passengers. With these uncertainties, the duration of the crossing varied. In 1665, it took New France's new Intendant, Jean Talon, 117 days to reach Québec; in 1678, the Arc-en-ciel made the trip in 35 days. Taking into account the requirements of the navigational season, it was better to set sail from France before May 1 and from Québec before the end of September. Since ships were not larger than 200 tonnes in the 17th century, accommodations on board were quite modest, and space was limited. Often, food and merchandise were spoiled by water seepage, and passengers had to make do with cold meals and soggy bedding. So great were the risks involved in reaching these far-off destinations, that surviving the dangers and perils of the sea depended as much on chance as on luck. Despite everything, most of the sailors and passengers arrived safely.
