Understand it.
Choose with purpose.
Choose the correct equipment, then make fit and care part of ownership.
Start with the activity and applicable requirements
Lifejacket selection begins with the activity, people and rules applying to the boat. Transport for NSW publishes its own guidance on approved types; owners elsewhere must use their relevant authority. A product review or brand reputation is not a compliance assessment.
Tell the supplier who will wear the equipment and with which clothing. Keep adult and child requirements distinct and ask for appropriate advice for each person rather than buying one model indiscriminately for everyone.
Make the fitting appointment count
Ask the supplier to demonstrate the exact model’s fit and adjustment with the clothing normally worn. Discuss any accessories and whether they are approved for that model. Try the practical actions involved in wearing and stowing the equipment as directed by the supplier.
A lifejacket may be technically suitable yet uncomfortable for a particular person. That makes a proper fitting conversation valuable. Do not modify straps, attachments or inflation equipment to solve a fit concern yourself.
Keep care and service visible
Follow the exact model’s inspection and service instructions. Spinlock publishes care guidance for its own equipment; use the instructions relevant to the jacket you own. Keep a record for each unit rather than treating a locker of jackets as one item.
Store the manuals, service details and approved accessory information where the crew can find them. Plan familiarisation before a trip. Ownership includes ongoing care, not simply the first purchase.
Compare the approaches
Use these differences to frame a conversation. This is a comparison of project approaches, not a ranking of brands.
| Approach | When to consider it | What to resolve |
|---|---|---|
| Individual regular-use jacket | A person wearing it frequently | Prioritise correct suitability and fit. |
| Guest equipment | Different people using the boat | Plan appropriate sizes, familiarisation and records. |
| Accessory-equipped arrangement | An approved combination for a specific use | Confirm compatibility and servicing together. |
A new cruising crew buys equipment
Two adults expect to wear different clothing across the season.
A considered approach
Arrange fitting with representative clothing, confirm appropriate equipment and record care requirements for each unit.
The best comparison happens on the wearer, not only in a catalogue.
Two mistakes worth avoiding
Using a review as a fit assessment
A reviewer’s experience cannot establish your own fit.
One service record for every jacket
Track each unit and its exact requirements.
Know the terms
- Approved type
- A type recognised under the applicable authority’s requirements.
