Perhaps we are driving down the wrong road with regard to SOLAS. Maybe we could try to convert the SOLAS law to exactly what it says it is, for Safety Of Life AT SEA. Create a new law for safety on the inland waters and get away from this periodic renewal of an exemption. How about a SOLOR (Safety of Lives On Rivers) law that recognizes such simple physical facts as shallow water, lack of tsunamis, narrow passages, bridges, locks, and all the other trials of river navigation that are different than those on the oceans?
