Lambo (boat) Wikipedia
The lambo or lamba is a type of Pinisi, Indonesian traditional merchant boat, akin to a cutter.
During the 1970s the Indonesian local vessels were progressively equipped with engines. Since machine installation did not fit well in traditional pinisi designs, lambos became a common alternative. In later years, their load capacities were increased until the current average of 300 tons, with the so-called PLM (perahu layar motor - motor sailing boat). Nearly every cargo boat seen nowadays in the local ports of Jakarta, Surabaya and Makassar are such modified lambos, still retaining some features from the original designs.
