Summary

The 1982 Radar, Navigation, Echo Sounder and Sonar Course was held from April 27 to May 7. This year's course for professional fishermen was attended by 11 students. It was felt that the smaller number was easier to handle in the compact training areas.

The first week of the course consisted of four (4) days at the Sydney Technical College learning and implementing navigational skills and mastering radar techniques. The College is being remodeled and the smaller number of students was easier to accommodate.

The second week was held at our training centre at Gore Bay and on board our research vessel "Kapala". Two nights of relevant films were also staged.

The course this year included two interstate lecturers and once again students came from all over N.S.W.
