4.5 Type of water and environmental conditions Six incidents (75%) occurred in enclosed waters (Gippsland Lakes – Lake King and Lake Victoria) and in two cases the type of water was not recorded. Visibility was poor in one incident, wind speed over 30 knots in two incidents, it was raining when one incident occurred and the sea was rough or very rough at the time of two incidents. 4.6 Contributory factors In three incidents the primary contributory factor was environmental (wind/sea state) with human factors also contributing (inexperience, navigational error and insecure mooring). In the other five cases, the primary contributors were human factors (navigational error, inexperience, lack of boat maintenance and ‘other’) with material factors making a secondary contribution in two cases (equipment-machinery failure and ‘other’ material factor). Incidents were described thus: • Hire boat experiencing difficulties in strong winds, blown on shore, and female occupant injured ankle when fending off • Hire yacht grounded, navigational error • Vessel was tied alongside jetty, jetty bollards and vessel broke as a result of strong winds and vessel washed ashore on rocks • Vessel broke mooring and drifted ashore, no damage caused • Broken down motor on tinny, required tow back to his jetty • Hire boat broken down due to fuel line disconnecting from tank • Hire drive vessel ran aground in shallow water • Hire boat ran aground in soft mud, vessel towed off 28
5. Results: recreational vessel incidents (2007/8) and hospital-treated boating injury (2006/7) 5.1 Recreational vessel incidents (2007/8) There were 1091 recorded recreational vessel incidents on the MIR in 2007/8, up from 913 in 2006/7. The 19% increase is possibly due to better reporting. Figure 4 shows the frequency of marine incidents by financial year from 1999/2000.

The inclusion criteria changed in 2005/6 with the introduction of the MIR and the ‘response only’ category covered vessel disablements, persons in trouble, false alarms and non-marine incidents. MSV requested that the ‘response only’ category in the 2007/08 report should be restricted to vessel disablements and persons in trouble and false alarms and non-marine incidents excluded. In this trend graph we have excluded false alarms and non-marine incidents from all years from 2005/6 for consistency. In 2007/8, 85% (n=926) of the recreational incidents were ‘response only’ incidents and 15% (n=165) were ‘serious incidents’. Figure 4 shows the frequency by year and category of incident and indicates that ‘response only’ incidents have increased each year from 2004/5. Serious incidents decreased in frequency from 2001/2 to 2005/6 but in 2007/8 returned to the number reported in 2002/3. Marine Safety in Victoria: July 2007 to June 2008 29
