spotters used where appropriate. There is a similarity to the sport of deep-water soloing, but this would normally be carried out by experienced individuals not wearing equipment suitable for coasteering. Coasteering is not usually intended as an 'always dry', climbing activity. Jumping into water: Coasteering "...often involves a series of jumps into deep water." Guided adventure experience The rocky cliff coasts of western Britain provide the world's principal location for organised guided coasteering, where it is available from over 100 activity centres. Usually half day or one day trips are offered at a variety of levels catering for beginners, intermediates and advanced. Some trips are especially slanted towards study of the coastal ecology. Some centres cater for parties of school children. Adventure races Coasteering may be included as one of the disciplines for a stage of an adventure race. This is especially common in New Zealand, but is also to be found in Australia, Canada, and the USA. Safety In 2015 in the UK a document giving safety advice for coasteering providers was published. Also in the UK, the HSE has an information sheet of good practice for the Adventure Activities Industry. Basic safety equipment Safety equipment reflects the environment in which the sport is performed and often includes: Wetsuit (for cooler waters outside the tropics) Protective clothing and gloves to prevent abrasions - may be provided by the wet suit Buoyancy aid Helmet Shoes to provide grip on rocks Wetsuit boots, trainers or canyoning boots (closed toes) Throw line Communications – hand-held VHF and/or mobile telephone Knife Hazards One hazard is the impact that occurs with the water surface when jumping into water from height and it was reported that, "If you jump from 20 feet (6 meters) above the water, you'll hit the water at 25 mph (40 kph) -- the impact is strong enough to compress your spine, break bones or give you a concussion." When diving and flipping into water along the intertidal zone there is an increased risk of receiving an injury including a spinal injury List of hazards Being swept away by currents Clothing or feet being caught in rocks or objects underneath the water surface Cold Water Shock Drowning Hypothermia Impact with rocks Impact with water surface Submerged objects "...like rocks, fishing gear, mooring lines and other under water hazards [that] may not be visible" Places known for Coasteering Hong Kong Wales England
