Naveron Lesch gave up working on traditional fishing boats to work as shark spotter in South Africa. If we sight a shark, we'll radio the spotter down on the beach and, if necessary, set off the shark siren to clear the water. If it's my day for a double shift, I'll move down to the beach and relieve the beach spotter. So you have to know shark behavior and decide how close the shark is going to get to the people in the water. The biggest shark I've seen was at Muizenberg Beach about five years ago, when I had trainees spotting with me.
