• Nearly half (48%) of vessels were 4.8-8m in length, 30% were 0-4.8m in length, 4% were 8-12m in length and 2% were greater than 12m in length. • Half the incidents occurred in the 3-month period November to January (late Spring and Summer); incidents were lowest in Winter (9%). • In all, there were 1,170 recorded contributory factors to response-only recreational vessel incidents. Material factors made the greatest contribution (61% of factors, mostly machinery and electrical equipment failures), followed by human factors (35%, mostly lack of maintenance and lack of fuel), then environmental factors (4%, mostly unfavourable wind or sea conditions). Serious incidents (n=165) • There were 165 serious incidents recorded on the MIR system in 2007/8, an increase of 26% on the previous year (n=131). • There were 9 deaths from 7 serious incidents recorded on the MIR system in 2007/8 compared with 5 deaths in 2006/7 (including two fatalities that were recorded under response only incidents). Deaths in 2007/8 were caused by drowning (3), impact injuries related to collisions (4) and burns (2) • Nine serious injury cases were reported on the MIR system in 2007/8, one more than in 2006/7, compared with 20 in 2005/6. • Grounding (36%), capsizing (18%) and collision (13%) were the leading causes of ‘serious incidents’. • More than one-quarter of ‘serious incidents’ involved open boats (26%), followed by full cabin cruisers (22%), half cabin cruisers (19%), yachts – keel boats (12%) and PWC (8%). • Twenty-two percent of vessels were 4.8m or less in length, 38% were 4.8-8.0m., 15% were 8-12m. and 6% were longer than 12m. • Over one third of vessels (35%) were cruising when the ‘serious incident’ occurred. Incidents also commonly occurred in fishing (19%), when the vessel was at anchor (13%) and during sailing (n=20, 15%). • Overall, 45% of recreational vessel occupants involved in serious incidents were recorded as wearing a PFD, compared with 62% in 2006/7. The wear rate for persons on vessels up to and including 4.8m in length was 58% (26/45), for vessels over 4.8m. in length the wear rate was 45% (69/152) and for vessels of an unspecified length the wear rate was 28% (9/32). • The frequency of serious incidents was higher in December (14.5%), January (17%) and March (17%). There were few incidents in the 4-month period May to August (12% in all). • Recreational ‘serious incidents’ mostly occurred in enclosed waters (73%), followed by coastal offshore waters (12%) and inland waters (10%). Thirty-seven percent of reported ‘serious incidents’ occurred on Port Phillip (n=61). Other common locations were Gippsland Lakes (n=28, 17%), Bass Strait (n=19, 11%) and Western Port (n=18, 11%). • Most ‘serious incidents’ occurred in clear weather with good visibility and wind speeds up to 8 knots. High proportions of swamping (62%), capsizing (50%) and vessel loss (60%) incidents occurred in choppy, rough or very rough water conditions. 8
• Human factors made the greatest contribution to recreational vessel serious incident (65% of factors, most commonly errors of judgement, inexperience, failure to keep proper lookout and navigational errors). Environmental factors (19%, mostly wind or sea state, tidal and bar conditions) and material factors (17%, mostly machinery, inadequate stability and electrical equipment failure) were less commonly implicated. Fatalities and hospital-treated recreational boating-related injuries recorded on injury surveillance databases (2006/7) Overall • There were three boating-related drowning fatalities recorded on the National Coroners Information System (NCIS) and 902 hospital-treated recreational boating injury cases (223 admissions and 679 ED presentations, non admissions) recorded on hospital injury surveillance databases over the period July 2006 to June 2007. Deaths • One fatality was a fisherman who drowned after falling into the water from a powered half-cabin vessel when putting out craypots. He was not wearing a PFD. The other was a fisherman who was found dead in the water with his life jacket tangled around his wrist. The only recorded contributory factor to the fatal incidents was non-wearing of PFD. Hospital-treated injury (n=902 cases) • There were 223 hospital admissions and 679 ED presentations (non-admissions) for boating-related sport and recreational injuries recorded on the VAED and the VEMD respectively. • Males were grossly over-represented in both admissions and ED presentations, accounting for 74% of all hospital-treated recreational boating injury cases. • Young adults aged 15-29 years, closely followed by adults aged 30-44 years, were more likely than other 15-year age groups to be admitted to hospital and to present to ED for boating-related injury. Age groups 15-29 and 30-34 years accounted for 35% and 29% of admissions and 41% and 26% of ED presentations, respectively, for boating-related injury in 2006/7. • Hospital-treated injury cases mostly occurred in water skiing and other towed water sports (41% of admissions and 44% ED presentations), general boating (15% of admissions and 36% ED presentations) and PWC riding (13% of admissions and 8% of ED presentations). Waterskiing and wakeboarding together accounted for 95% of towed water sport admissions and 81% of towed water sport ED presentations. • The major specific causes of injury were: falls (24% of admissions and 32% of ED presentations) and hit/ struck/crush injuries involving objects (13% of admissions and 32% of ED presentations). There were 9 non-fatal drowning/submersion hospital-treated cases in 2006/7 compared with 22 in 2005/6. • The lower extremity was the most commonly injured body site for both admissions and presentations, accounting for 32% of all hospital treated injury, followed by the upper extremity (25%) and head/face/ neck (22%).
