A clause in a charterparty may allow either the charterer or the owner to load cargo over the original cargo, if there is available space and deadweight capacity available. However, overstowing may cause problems with the time for discharge of the original cargo as occurred in the case of The Maxico I, 1990. (See the last paragraphs in Optional cargo clause above.) Overstowing by the owner may also lead to claims if the cargo beneath is damaged.
