We encourage prospects to evaluate a rescue net on the following:
Vertical length (Should be based on attachment length/freeboard): The freeboard/attachment length is the vertical distance from where the net is fastened on the vessel down to the water line. Nets should be 1.5 meters to 2 meters (60 to 80 inches) longer than the freeboard. This is to provide an easier first step from within the water, and provide enough length to use as par buckle.
Width: We recommend at least 120 cm (4 feet wide). We recommend a wider net where possible. A wider rescue net is preferable for lifting injured persons with possible back, neck or head injury. In addition a wider net will provide more room and strength to allow for persons to use the net as an emergency ladder.
Flexibility of use during different rescue scenarios. Can the net be used as an emergency ladder, scramble net, or a rescue cradle (par buckle)? Can the net be manually deployed?
Weight: The lighter the net, the easier it will be to manually deploy by one to four persons, without the use of a crane or davits
Stowage room required. Typically a net that can be stowed away from the elements will provide a better long term investment.
