AI-generated summary
A 62-year-old woman drowned after a recreational fishing boat sank in Port Phillip Bay. The vessel, a modified 1980s Huntsman, had multiple structural deficiencies including corroded hull below bungs allowing water ingress, poorly sealed deck areas, and unsealed cable/fuel line penetrations. The bilge pump lacked automatic activation. The boat became stern-heavy due to weight and aft loading, reducing freeboard. Rough conditions (1-1.5m waves) and the sudden wave impact caused capsizing. While immediate rescue efforts were commendable, the preventable factors were vessel-related: lack of mandatory seaworthiness inspection at registration, poor maintenance, and inadequate bilge pump design. The coroner highlighted that modified vessels in Victoria are typically detected as unsafe only post-incident, representing a systemic preventability opportunity.

Error types
Contributing factors
- Vessel structural deficiencies including corroded hull and worn bungs allowing water ingress
- Unsealed cable and fuel line penetrations through transom
- Bilge pump without automatic float switch requiring manual activation
- Re-glassed deck allowing water to enter watertight void beneath, creating free surface stability issues
- Aft weight trim reducing freeboard and stability
- Rough sea conditions (1-1.5m waves) with wind gusts 26-30km/hr
- Absence of mandatory vessel inspection process at registration in Victoria
- Inadequate vessel maintenance and lifting laminates on hull
- External platform modifications affecting vessel righting ability
Coroner's recommendations
- Develop and implement a vehicle inspection process at the time of vessel registration and acquisition or transfer of ownership, akin to Road Safety (Vehicles) Interim Regulations 2020 (Vic), to proactively identify deficiencies and require remedial work
- Ensure all boats fitted with electrical bilge pumps in enclosed bilge areas have automated switches or floats, or alarms if a manual bilge pump exists
- As part of seaworthy inspections, retrospectively attach builders' plates which determine the number of people, the conditions for which the vessel is suited, and the maximum engine capacity
