Lifejacket Lifesaver - it's not a lifesaver if you're not wearing it
Personal Flotation Devices - PFD's/Lifejackets
One PFD of suitable size should be carried for each person on board (12 months and over). It is not enough just to have them on board - they should be accessible at all times and be sure you and your passengers know how to put them on quickly.
PFD Type 1
Has sufficient flotation to support the body and head and reflective tape for visibility. The flotation collar keeps your head above water.

Use: For use in smooth, partially smooth and open waters. SOLAS and Coastal Lifejackets are accepted as a PFD Type 1 for recreational safety equipment purposes. Must comply with Australian Standard 1512.
PFD Type 1
PFD Type 2
Will keep you afloat but does not have a collar to keep your head above water. Suitable for use in smooth and partially smooth waters.

Use: Good for waterskiing, PWCs, sailing boats and dinghies. Must comply with Australian Standard 1499
PFD Type 2
PFD Type 3
Has the same buoyancy as PFD Type 2 although colours are not as visible. This may be a specified buoyancy wetsuit.

Use: In smooth waters and only where the user is likely to be in the water for a short time. Must comply with Australian Standard 2260.
PFD Type 3
Coastal and SOLAS (Safety of Life at Sea)
These jackets have more flotation than a PFD Type 1. They are bulky lifejackets designed to keep the body afloat for long periods. They have reflective tape and a whistle to attract attention. These jackets are mostly carried by commercial boats and are recommended to be carried by boats operating long distance offshore.
