Sailing Foundation
The Safety at Sea committee of the Sailing Foundation in Seattle, Washington decided in 1998 to conduct an objective study into the common safety of harnesses and tethers used in sailing.
The dynamic test results were the most dramatic because 8 percent of the 21 harnesses and 47 percent of the 21 tethers that were then available on the market failed the test.
Water Test
The first test was an in the water test. Here a Crew Overboard wearing different brand harnesses with 3ft and 6ft assorted tethers, were towed through the water. The reaction of the wearers was noted, i.e. if they were comfortable, their ability to breathe easily when towed and also how easy it was to reboard the yacht. It was also noted how easily the snap shackle at the harness could be released when under load.
Static Test
The second test was a static one where the examiner conducted a physical inspection of the harness and tether. Here comfort, ease of strap adjustment, the width of load bearing straps, magnetic properties and the weight of the harness, were recorded. The workmanship in the construction of these items was carefully examined
Another phase of static testing and trying to keep it as real as possible in summer or winter sailing weather, crew were timed as to how long it took them to don the different harness with and without foul weather gear. Weight of harness, degree of difficulty strapping it on, ease of adjustment, pinch points, uncomfortable strap rubbing etc. all came under their consideration.
A test was carried out by hoisting the wearer by his harness off the ground with a dingy hoist. Points noted were again ease of breathing and also what happened with the harness when the wearers raised their arms when trying to climb back onboard.
The Dynamic Load Test
The dynamic load test was done to see how the harness and its tether would react when attached to a 220 dummy and dropped 6ft 6 inches. To eliminate the tether as a variable when testing a harness, each harness had its own brand new tether attached. The same when testing tethers, a same type of new harness was used so as eliminate the harness as a variable.
To improve the shock loading qualities of nylon webbing, the tethers and harnesses were first soaked in water.
Buy With Confidence
Since these test were carried out back in 1998 the quality, comfort and safety of these product have been greatly improved and well known brands can be bought with confidence.

Frank has been living the dream for close on 30years. It started when he built his own 34ft sailboat(took 8 years) and launched Footloose in 1994. He has been working as a sailing charter boat captain for 8 years in the Caribbean Windward, Leeward Islands and BVI's. Having sailed over 40,000 sea miles in Footloose, and on other yachts around the world, through his web site http://coolboatingsupplies.com he hopes to encourage old and new boaters, by reviewing marine products, to enhance their boating experiences.
Sailing, fishing and surfing is his passion and he has always believed that with the right equipment, life is a breeze.
