The International Convention on Load Lines (ICLL) is an international agreement, under the auspices of the IMO, which aims to mitigate the dangers of overloaded vessels traveling on the high seas. It applies to vessels traveling internationally between the ports of signatory nations.
The first ICLL was adopted in 1930, aiming to ensure adequate reserve buoyancy. The 1966 convention expanded provisions to consider the watertight integrity of the hull and minimum stability levels. This convention was adopted April 5, 1966 and entered force two years later on July 21st.
Amendments were made in 1971, 1975, 1979, 1983, 1988, 1995, and 2003. Of these, only the 1988 and 2003 amendments received enough support to enter into force.
