Dr. Dobbins demonstrated how Human Factors impact on all operations at sea. He showed examples of accidents and explained, ?Navigators cannot be trained to cope with every single possible situation that they can expect to en- counter. If a situation, environment or location is new then the navigator is unlikely to have had the opportu- nity to gain the experience needed to make good decisions based on local knowledge. Even an experienced operator will encounter new situations and in that perspective they are a novice. The DYNAV methodology / System supports good decision making in new or unique situations for all levels of operators.? The helmsman?s task of driving the boat alters with higher speed. There is a greater responsibility for own craft and other craft that is controlled by the Internation- al Regulations for Preventing Collisions at Sea (IRPCS). Slow going vessels may not be expected to keep a lookout to the horizon trying to identify high-speed vessels that they should give way to. Therefore, high speed craft have a greater responsibility when encountering situations with signi cantly slower craft. STANDARDIZED METHODOLOGY = INTEROPERABILITY The use of a standardized methodology also facilitates interoperability between agencies and nations. The DY- NAV process is primarily designed to support Green Wa- ter (littoral / coastal) and Brown Water (riverine / estuary) water environments but can also be used for Blue Water (open sea) operations. DYNAV is designed to work with all vessels in all situations. Due to the nature of current in- ternational operations the focus is on Rigid Hull In atable Boats (RHIB), planning craft, novel hull forms and hov- ercraft. The DYNAV standard is designed to be a robust process that may be adjusted for use with speci c sectors including military, security, Search and Rescue (SAR). Equipped with standardized DYNAV information, the fast boat driver is able to conduct the next turn or ac- tion with con dence. Captain Forsman explained, ?In DYNAV, information is communicated with a standard protocol. The navigator gives the driver a general brie ng about the situation then there is a set of standard instruc- tions that gives answers to fundamental questions; Where are they going now? Where and how to execute the next turn? Where are they are going next? Where should they not be? How do they know they are safe?? The traditional school of navigation recommends know- ing the vessel?s position at all times. This is simply not pos- sible for high speed craft and the problem is accentuated as speed increases. Conventional navigation has a require- ment for Location Certainty. DYNAV recognizes that in high speed operations it can be as important to know where ?the craft is not? as knowing where ?the craft is?. The cross checking of information sources within the Situation Awareness (SA) process reduces the risk of er- rors and enhances the navigators Location Certainty to facilitate the ?Plan? phase of the DYNAV method. Gaining and maintaining SA includes the procedure of checking and cross-checking sources of location and environmental information to inform the navigator and enhance the cer-tainty of the crafts current status within its surroundings. These sources of information may include visual, paper chart, radar, electronic chart, heading, course over ground, depth and GPS.DYNAV C URRICULUM The FRC International DYNAV System covers all as- pects starting with DYNAV PRE learning that can be delivered as eLearning or in the maritime classroom. DY- NAV C2 is on-water training that focuses on Command & Control teamwork skills where the navigator uses the TRAININGCOLUMN?The Swedish archipelago is a complex environment with numerous un-marked islands. Old school navigation was neither safe nor efÞ cient and an alternative methodology was required. The Amphibious Corps high speed navigation system was then adopted by the Swedish Sea Rescue Society (SSRS) and adapted to their circumstances. After a number of serious accidents with commercial high speed craft the Swedish Maritime Authority introduced legislation that called for mandatory high speed navigation training.?
