Passage Planning Guide: Straits of Malacca & Singapore IT103565
7th ed. The basic principle of the Guide is to con a ship through the straits, either eastbound or westbound, giving salient information for the each leg of the voyage. The advantage of the new electronic version lies in its functionality allowing for update for company-specific, ship-specific or time-specific differences thus tailoring the hardcopy Passage Plan to a unique document suited to the individual ship for the date and time of transit. The Guide is informed by marine experience form many shipmasters transiting the straits.
