FV Cassandra: vessel capsize likely whilst retrieving snagged trawl net from seabed hook-up, resulting in drowning. FV Dianne: vessel capsize (cause open finding - either drogue rope fouled propeller or wave-induced instability), resulting in drowning.
AI-generated summary
Joint inquest into eight fishermen lost at sea from FV Cassandra (2016, two deceased) and FV Dianne (2017, six deceased). FV Cassandra capsized while attempting to retrieve snagged trawl net caught on seabed reef; likely crew were on aft deck when sudden release caused violent rollover. FV Dianne capsized in moderate seas; cause uncertain but may involve drogue rope fouling propeller or instability from wave action. Both vessels lacked automatic EPIRB activation and life raft deployment failures occurred. Critical clinical/safety lessons: automatic emergency systems critical in disorienting crisis situations; 12-hour notification delay in Dianne case unacceptable; vessel monitoring system's 'failure to poll' alerts must be implemented immediately to authorities; simple improvements (emergency lighting, grab bags, PLBs, secured equipment) are inexpensive and life-saving; crew disorientation in underwater/capsized scenarios is profound even for experienced divers; manual activation of safety devices often impossible during violent capsize. Systematic barriers (departmental obstruction, grandfathering of vessels without stability reassessment) must be addressed.
AI-generated summary and tagging — may contain inaccuracies; refer to original finding for legal purposes.
FV Cassandra: attempted retrieval of snagged net using high-tension winching method instead of safe alternatives such as snatch block technique
FV Cassandra: possible reduced reserve stability from earlier twin-boom trawler modifications not reassessed after refit
FV Cassandra: vessel operating near limit of safe trawling area close to uncharted pinnacles and reefs
FV Cassandra: life raft painter entangled on wheelhouse structures preventing deployment
FV Cassandra: manual EPIRB insufficient time to activate during rapid capsize
FV Dianne: inadequate securing/lashing of drogue on aft deck during steaming
FV Dianne: drogue rope fouled propeller, eliminating forward propulsion in sea state
FV Dianne: 12-hour delay in authorities receiving distress notification due to failure of manual EPIRB activation and lack of automatic 'failure to poll' alerts from VMS
FV Dianne: vessel monitoring system 'failure to poll' safety function not implemented despite existing capability for nearly 30 years
Both vessels: lack of automatic/self-activating EPIRBs (not yet mandated at time of incident for these older vessels)
Both vessels: absence of emergency exit lighting in enclosed spaces
Both vessels: absence of emergency grab bags with portable air source
Both vessels: crew unable to access safety devices during disorienting capsize event
Both vessels: unsecured wheelhouse equipment (e.g. refrigeration) may have impeded escape routes
Systemic: regulatory inaction on known safety improvements; departmental obstruction regarding VMS safety implementation
Coroner's recommendations
Industry be encouraged to place emergency Grab Bag of necessary basic equipment in sleeping cabin and near helm to assist crew to exit capsized vessel
Self-illuminating LED strip-lighting and emergency exit signs be encouraged in existing vessels within two years; after two years, consider mandating in all commercial fishing vessels
Industry be encouraged to secure all bulky wheelhouse items by restraining straps or bolts to prevent movement during capsize
Fishermen be encouraged to wear inflatable style PFD vest with PLB whilst working on decks or at helm
Regulatory authorities and industry investigate appropriate workable solutions to enable doors to be opened against water pressure whilst maintaining designed purposes
Regulatory authorities and industry review use of quad gear in Sandy Straits area for trawling due to uncharted pinnacles and reefs
Regulatory authorities and industry investigate and proceed towards ensuring all vessels have SMS copy of original plans, modification details, and stability test documentation; duplicates held by owner on land and by regulatory authorities; mandatory stability test report at time of vessel sale if configuration changed from original
SMS should include safe methods for retrieving snagged net from hook-up by snatch block or leaving net for later retrieval
Department of Agriculture & Fisheries immediately implement sharing of VMS 'failure to poll' function to notify QPS by SMS and email of any vessel failure to poll
