DWS uses the
sport climbing grading systems (mostly French sport climbing grades) with an additional S-grading system to reflect the unique risks of DWS on any route; DWS routes can vary from less than to over in height at the extreme end. Competition deep-water soloing has become popular, particularly in head-to-head "dueling" formats, and the "Psicobloc Masters Series" (2011, 2012–2018), which later evolved into the "Psicobloc Open Series" is one of the most notable DWS competitions.

as the DWS climber encounters hazards that are unique to DWS, including injury or trauma on impact with the water or hitting hazards in the water (particularly from higher falls or uncontrolled falls), risk of drowning in rough seas and hitting the rock face before entering the water. Changing tides is a serious risk in DWS, as routes that might be very safe at high tide can become dangerous at lower tide, bringing underwater hazards into play.
[
DWS routes can vary from safe "bouldering-type" overhanging routes that are only a few metres in height above calm clear deep water, where any fall is almost guaranteed to result in clean low-speed entry into the water; which are graded S0-S1 DWS routes. At the other of the scale are DWS routes that are high (e.g. over , and going up to even in height at the most extreme level), and where the climber needs to push themselves off the rock face to ensure that they enter the water cleanly, and control their surface impact as it will be at high speed; which are graded S2-S3 DWS routes.][
]
Types of routes and locations
While DWS can be done on any rock face over or beside the water, it is particularly suited to certain areas that have at least slightly overhanging rock faces (i.e. ensuring the DWS climber lands in the water), have clear and deep water (i.e. so that any underwater hazards can be identified and/or avoided), and are in warmer climates (so the DWS climber does not have to wear a wetsuit, and the water is generally calmer).
Several locations that meet most of the above criteria have become particularly attractive for DWS:[

venue, and as time progressed, Riera moved onto the nearby sea cliffs where they established DWS routes. Riera and his companions named it "psicobloc" (translated into English, means "Psycho Bouldering"),[ and published articles and photographs in climbing magazines on their activities. Towards the end of the 1980s, Miquel, aided by Pepino Lopez, Xisco Meca, Pepe Link, and Miki Palmer, had discovered the short sea cliffs of ''Cala Varques'', ''Cala Serena'', and the impressive cliff in ]Porto Cristo

, which was to become known as ''Cova del Diablo''.[ Three notable routes were established at ''Cova del Diablo'': ''Surfing in the Bar'', ''Surfer Dead'', and ''Surfing Bird''.][
The 1990s saw an explosion in Britain for what was called "Deep Water Soloing" (DWS), starting with Nick Buckley's ascent of ''The Conger'' (1983).][ Britain's southern coast saw new DWS routes from the Cook brothers, Mike Robertson, Steve Taylor, and Pete Oxley.][ In 1996, the British Climbers' Club, published ''Into the Blue: A guide to Deep Water Soloing in Dorset'', the first-ever DWS guidebook in the world, and proposed an evolved S-grading system and climbing style to Britain.][ In 2001, British climber Tim Emmett received an email from Miquel showing ''Cova Del Diablo'' and led to a trip by Emmett with other leading climbers such as Mike Robertson, Neil Gresham, and Austrian Klem Loskot.][ In February 2002, Robertson published an article titled 'Sympathy for the Devil' in ''Climber'' magazine describing ''Cova Del Diablo'' and the twenty-six new routes (from 4+ to 8a) that Emmett's party had added to the existing three routes.][
The publication of Robertson's article led to more international teams coming to ''Cova Del Diablo'' to create additional routes and explore new Mallorcan cliffs such as ''Cala Sa Nau'', ''Cala Barques'', ''Cala Mitjana'', and ''Porto Cristo Novo''.][ These teams also introduced Dutch climber Toni Lamprecht to Mallorcan DWS, which resulted in a vast number of new lines being established, chiefly at ''Cala Barques''.][ DWS became more mainstream and globally recognized amongst climbers when a couple of short films were made by climbing filmmakers such as Udo Neumann in 2001, and Josh and Brett Lowell in 2003.][ The films featured some of the sport's pioneers: Emmett, Lamprecht, Klem Loskot, and a newcomer to the style, Chris Sharma.]
In September 2006, DWS came to international attention when Sharma completed the right-hand finish to a line that climbed the underside of the dramatic Es Pontàs arch in Mallorca and carried a grade of , the hardest-ever DWS grade. Sharma had been looking for a DWS-equivalent to his 2001 sport climb, '' Realization'', also , and his first free ascent was featured in the iconic 2007 film ''King Lines''.[

Competition DWS
There have been numerous competitions held in DWS, the most notable of which is the "Psicobloc Masters Series" that began in 2011 in Bilbao, Spain organized by Spanish climber Finuco Martinez. From 2013 to 2018, the "Psicobloc Masters" was held in Utah Olympic Park and organized by a consortium that included Chris Sharma. In 2019, the series moved to Montreal, and was later rebranded as the "Psicobloc Open Series".
The general format is a circa outdoor artificial climbing wall that severely overhangs a circa swimming pool. Climbers "duel" in head-to-head races on the wall in a series of knock-out rounds until the ultimate winner is decided. Climbers compete in men's, women's, and youth's formats.[

Risks
DWS presents a number of specific risks not normally encountered in rock climbing.
* Water entry: A fall into deep water from a height of over can seriously injure the climber, particularly if the entry is not controlled.[ On difficult DWS routes, a fall can happen spontaneously and from a position where the climber was on an overhang—thus falling onto their back. DWS climbers build up their skills of controlling body position on water entry at the lower S-grades.][
* Underwater hazards: There may be rock features under the water's surface that the falling DWS may hit on a forceful or high-speed water entry. DWS climbers sometimes use an "armchair landing" technique to limit the depth of water they penetrate which involves adopting a quasi-sitting position while falling.][ This technique is very effective and can absorb a fall in just of water, but "armchair landings" are difficult to master and dangerous at greater heights.][
* Effect of tides: All of the S-grades are specific to high tides. A DWS route graded S0-S1 at high tide, can become an S2 or S3 at low tides (e.g. Neil Gresham's 2012 DWS route ''Olympiad'' in Pembroke in Wales, has a DWS grade of F8b S1 at high tide, but is a non-DWS route with a traditional climbing English grade of E10 6c at low tide][); particularly if underwater features come increasingly into play. DWS climbers need to understand the tidal system in the area and plan their climbs accordingly.][
* Rough seas: DWS climbers have drowned, overcome by rough or swelling seas from which they were unable to escape (and often in a fatigued state).][ DWS climbers avoid climbing alone and have a support climber either in an inflatable dingy or in a position to lower a rope from above.][

Equipment
Like free solo climbing

DWS needs very little climbing equipment outside of the chalk bag and rock climbing shoes. A number of additional items of equipment have become common amongst DWS climbers, including:
* Bench seats/ladders. Some DWS routes have makeshift wooden benches and small rope ladders installed at the base of the routes, hanging from pieces of protection, to enable the DWS climber to access the route, and rest/dry-off between attempts.[
* Inflatable dingy. DWS climbers sometimes employ a lightweight inflatable dingy that they can anchor at the bottom of the route and use for both recovery after falls, and resting between attempts; it can also be used by a second DWS climber for stand-by assistance.][
* Tape harnesses. DWS climbers do not typically use a ]climbing harness
A climbing harness is a piece of equipment that allows a climber to tie in (climbing), tie in to the safety of a rope. It is used in climbing, rock and ice climbing, ice climbing, abseiling, and lowering; this is in contrast to other activities r ...
; however, many DWS routes require the climber to abseil down the rock face to access the route (unless they can use the inflatable dingy). For this, they can use a makeshift harness made from a climbing sling.[
]
Grading
French sport grades
The main DWS grade is "technical grade" which reflects the difficulty of the hardest movements or sequences on the route. The French sport climbing grades (e.g., 6a, 6b, 6c, ... 8b, 8b+, 8c, etc.) are generally the most popular technical grades in European DWS. In England, the traditional English grading system is sometimes used, although where French sport grades are quoted in England an "f" suffix is often placed before the grade to clarify that it is a French grade and not a British grade (e.g. f6a to distinguish from the British E4 6a).
S-grades
In circa 1995, British DWS climbers developed the S-grade system to give an additional grade for the objective level of danger that deep water soloing a given route presented to the climber in addition to the "technical difficulty" grade (above).[ British climbers felt that the English E-grade suffix reflected traditional climbing dangers (e.g. how good is the level of protection available to the traditional climber on the route), and not the dangers specific to the DWS climber (who was not going to be placing traditional climbing protection on the route); it is akin to the " R/X" suffix of American grades.][ For example, British climber Neil Gresham's 2012 DWS route ''Olympiad'', has a DWS grade of F8b S1, but a traditional climbing English grade of E10 6c.]
The four levels of S-grade, as described by Mike Robinson in ''Deep Water'' (2007), are as follows:[
* S0: "Safe at most tides, not particularly high crux moves. Avoid bottling out of an S0 if possible. These are essentially safe, so climb until you fall. Commitment normally pays off!"][
* S1: "Care required; either the tide or the water depth needs checking, or maybe there is a highish crux on the route. Remember that, in big-tide venues, a huge tide and good timing can turn an S1 into an S0".][
* S2: "A little more care than S1 required. Possibly spring-tide only (higher water levels). Check your tide timetable. 'Landings' can be more significant – maybe a crash landing into shallow-ish water is required, or a slight 'push' to clear rock or a slight slab/reef below. Likely to have a high crux".][
* S3: "Expect the water to be either too shallow or too far away! You can't really afford to fall off an S3 without a large measure of control or timing. Failure on the route might require a full body-length crash landing into the deepest water available, or a long and scary downward flight. If you're operating in a tidal venue, wait for the biggest high tide possible".][

Notable ascents and milestones
A number of DWS ascents are particularly notable in the sport:
* 2006: '' Es Pontàs'' , Mallorca

( ESP). First ascent was by Chris Sharma who left it ungraded but famously took over 50 attempts to complete the dyno high up on the dramatic sea arch; the DWS route of ''Es Pontàs'' launched DWS to a much wider global audience and its first ascent featured prominently in Sharma's iconic 2007 climbing film, ''King Lines''. Was repeated by Jernej Kruder (2016), Jan Hojer (2018), and Jakob Schubert in 2021 with a consensus that the grade is circa 5.15 (being a high DWS brings additional complexity in grading), which was the first-ever in DWS.
