The right purchase starts with an approved model suitable for the user and activity. Try the exact version and use the manufacturer’s guidance and applicable local requirements.
Separate product labels from the decision
Spinlock’s Deckvest 6D range includes versions marketed as 170N and 275N, alongside model-specific approvals and instructions. The number on a product name is not enough to establish suitability for every wearer or activity. Ask the supplier to show the actual label and documentation.
Describe where you sail, the clothing and equipment you normally wear, and any fit concerns. Check the relevant Australian jurisdiction’s requirements for the vessel and activity. This guide does not provide an individual flotation assessment or replace that official guidance.
Try the complete wearing arrangement
Compare the exact candidates with the clothing you intend to use. Ask the supplier to demonstrate adjustment and identify the permitted wearer range. Check access to the controls and how the harness, if fitted, sits with other equipment.
Do not turn a showroom fit check into an unsupervised inflation experiment. Use the manufacturer’s instructions and appropriate supervised demonstrations. The goal before purchase is to understand the model, its adjustment and the routine you will need to follow.
Compare versions beyond buoyancy
An apparently similar jacket may differ in harness options, activation system, lights, sprayhood or included accessories. Request the exact product code and written contents. If a harness release feature matters, verify that it is included in the quoted version rather than an optional alternative.
Ask about local service support and the correct replacement components. The useful ownership cost includes inspection and servicing, not just the jacket. Avoid choosing a version that you cannot readily support where the boat is based.
Choose with the supplier’s reasoning recorded
Ask why the proposed model suits the intended use and what assumptions the recommendation depends on. If clothing or activity changes, ask whether that affects the choice. Keep the instructions and product record with the boat’s safety-equipment information.
An illustrative crew buying several jackets should assess the wearers individually rather than simply ordering identical units for convenience. Similar appearance may help organisation, but it does not establish suitable fit for everyone. Agree how each item will be identified, checked and maintained.

Buying questions, answered
Is 275N automatically the best choice?
Do not choose solely from the number. Suitability depends on the exact product, wearer, activity and manufacturer’s guidance, together with applicable requirements.
Does a harness come with every inflatable lifejacket?
No. Check the exact model and included features, including any optional release system and the instructions for its intended use.
