British marine safety gear manufacturer Crewsaver introduced its line of inflatable PFDs at the Miami International Boat Show. Models range from the basic Crewfit 150 and 165, to the ErgoFit 290, designed for serious bluewater work. Higher end models include pockets for personal locator beacons, hoods and integrated harnesses. The two models I tried on were comfortable and easy to adjust. Prices start at around $225.
