[2] Leti leti from Giligenting, easily recognized by squared 'doghouse' abaft the main gabled deckhouse, were common sight at the late 1940s in ports all around the Java Sea, from Sumbawa to Riau.
[8] The leti leti was an optimal design of small sailing cargo vessel for the Java sea, stoutly built with great load carrying capacity for its length and draught.
Traditionally Madurese traders brought cattles to East Java from as far as Roti island and Kupang in Timor, they also carried salt, rice, and assembled goods out from Surabaya.
[11] Modern leti leti, nevertheless, is not the right type of trading perahu for Eastern Indonesian islands: This boat couldn't sail through low tide straits or they're needed a long time to pass, or dealing with blowing winds and gusts around mountainous islands, so the type of perahu used there currently is the lambo.
Originally they got it from Madurese living alongside them in the mixed communities around Java sea such as Marumasa, Masalembu, and Kangean islands, but the current Mandarese vessels always different from Madura vessels.
Their difference are Mandar-styled rudder mounting, flat roof on its deckhouse, the absence of paint pattern and black-colored stempost, but always clean, tidy, and organized.
