Sizing around weight rather than age
Spinlock's central message is that a child's lifejacket should be selected primarily around the wearer's weight rather than a broad age description. The Junior Collection spans products intended for very small children through to junior sailors weighing up to 50kg.
That approach matters on family cruising yachts because children of similar ages can differ significantly in body size and buoyancy needs. Correct fit also determines whether straps, collar and flotation panels remain in the intended position after a child enters the water.
NEMO, NEMO+ and CENTO cover different stages
The range includes the Deckvest NEMO, Deckvest NEMO+ and Deckvest CENTO rather than trying to stretch one design across every size. Spinlock lists the foam NEMO for children in the 15–30kg range and positions the wider collection to cover smaller and larger users around it.
Features across the range focus on secure fitting, comfort and ease of adjustment so children are more likely to keep the equipment on while aboard. That is particularly important on longer passages where a poorly fitting lifejacket can quickly become uncomfortable.
Family cruising has different equipment demands
Adult offshore lifejackets are often specified around harness integration, sprayhoods, lights and inflation systems, while children's equipment has additional fit and support requirements. A family yacht therefore needs more than simply smaller versions of the adult jackets carried for the crew.
Owners should also plan for growth because a jacket that fitted at the start of one season may not fit correctly a year later. Regular fitting checks are a sensible part of pre-season safety preparation for families who cruise frequently.
The product is only one part of child safety afloat
A correctly sized lifejacket is an important layer, but supervision, guardrail discipline and clear cockpit rules remain essential. Harness or tether arrangements should also be considered separately where children are on deck in conditions that create a genuine fall-overboard risk.
Spinlock's collection helps make the equipment choice more structured by presenting defined products across the weight range. The useful takeaway for yacht owners is to inspect each child's fit individually rather than assuming one junior size will suit everyone on board.
