When there has been no proper groups of charterers with whom to negotiate a particular charter, for instance. "Gencon" Charter it is issued as a "recommended" charter. The same is the case if the parties with which a charter has been negotiated will not be able to bind their members to use the charter as a clean document. This is the position, for instance, for the "Norgrain" Charter and the 'Nuvoy" Charter. Whereas BIMCO naturally wishes the printed text of a "recommended" charter to be followed by charterers and shipowners. there were no compulsion in this respect.
