Unfortunately, the freeboard measurements for PFD's are very much dictated by body composition so we would not be able to offer a blanket recommendation in regards to the freeboard measurements for each use case. What we can say is that quite obviously, the higher the buoyancy and the type classification, the more freeboard a PFD will have. Type II PFDs – or offshore buoyant vests – are designed and developed for environments where wearers find themselves in isolated or rough waters. Offshore PFDs offer high buoyancy, and are suitable for most water conditions, and are designed to prop you quite high up in the water. If you are looking for an inflatable, a Type II vest is what you will want. If you are comfortable in Foam, Type 1 will give you the highest freeboard.
