The British Sub-Aqua Club or BSAC has been recognised since 1954 by UK Sport as the national governing body of recreational diving in the United Kingdom.[3]

The club was founded in 1953 and at its peak in the mid-1990s had over 50,000 members declining to over 30,000 in 2009. It is a diver training organization that operates through its associated network of around 1,100 local, independent diving clubs and around 400 diving schools worldwide. The old logo featured the Roman god Neptune (Greek god Poseidon), god of the sea. The new logo, as of 2017, features a diver with the updated BSAC motto "Dive with us".

BSAC is unusual for a diver training agency in that most BSAC instructors are volunteers, giving up their spare time to train others, unlike many other agencies, in which instructors are paid employees, or self-employed.

Given that UK waters are relatively cold and have restricted visibility, BSAC training is regarded by its members as more comprehensive than some. Specifically it places emphasis on rescue training very early in the programme. BSAC also maintains links with other organisations, such as NACSAC.

Science writer and science fiction author Arthur C. Clarke was a famous member of BSAC.[4][full citation needed]

The current President of BSAC is the Prince of Wales. His father Charles, and grandfather Philip also held that position and his brother Harry also trained with BSAC.[5]

## Recognition

[edit]

BSAC is recognised by the successors of the Sports Council as the National Governing Body (NGB) for Sub Aqua within the United Kingdom. It has held this status since 1954. 'Sub Aqua' (or Sub Aquatics) is a broad term that includes both recreational underwater activities such as recreational diving and snorkelling, and competitive underwater activities including underwater sports such as Octopush. It is also recognised by Sport England as the NGB for Sub Aqua in England.[3][13]

BSAC is one of three NGBs representing 'Sub Aqua' in the constituent countries of the United Kingdom. The others are the Northern Ireland Federation of Sub-Aqua Clubs (Northern Ireland) and the Scottish Sub Aqua Club (Scotland) with the British Sub Aqua Club being the NGB for the United Kingdom as a whole; a role it has held since 1954.[3][13] Wales has been represented by the British Sub Aqua Club since January 2016 when it replaced the Welsh Association of Sub Aqua Clubs.[14]

## Diver Training Programme

[edit]

A chart explaining BSAC diving progression.

### Diving Qualifications

[edit]

BSAC currently has seven diver qualifications (five standard and two intermediary):[15]

* Discovery Diver: Basic skills, supervised diving (depth limit 12 m).[16][a]
* Ocean Diver: Basic skills, non-decompression diving (depth limit 20 m).[17]
* Advanced Ocean Diver: Further Basic skills training, navigation, nitrox (up to Nitrox 36%), non-decompression diving (depth limit increased to 30 m with a series of 5 m progression dives).[18][b]
* Sports Diver: Rescue, navigation, nitrox and decompression diving (depth limit increased to 40 m with a series of 5 m progression dives).[20]
* Dive Leader: Dive leading, dive planning and management, and rescue management (depth limit increased to 50 m by completing a selection of experience dives).[21]
* Advanced Diver: Fully trained diver capable of leading a group of divers in normal club activities.[22]
* First Class Diver: Trained to lead a group of divers carrying out a project. This is nationally examined with a two-day practical test.[23]

### Instructor Qualifications

[edit]

BSAC has eight instructor grades:[24]

* Assistant Diving Instructor: Trained but unqualified. Must be supervised when instructing.
* Theory Instructor: Qualified to instruct unsupervised in the classroom.
* Assistant Open Water Instructor: Qualified to teach open water under supervision.
* Practical Instructor: Qualified to instruct unsupervised in open water.
* Open Water Instructor: Qualified to supervise other instructors in classroom and open water training.
* Advanced Instructor: Trained to teach advanced skills, such as boat based skills and group diving techniques.
* Instructor Trainer: Qualified to staff Instructor events.
* National Instructor: Leads Instructor Training courses and BSAC National exams.

### Grades no longer awarded

[edit]

The following grades which are no longer awarded may still be encountered:

* Novice I: A diver who has completed the extensive sheltered-water (i.e. pool) training of the BSAC syllabus of the time, but has not yet dived in open water.
* Novice II: A Novice I diver who has completed two open-water assessment dives.

The distinction between Novice I and Novice II was mostly for practical reasons to do with the difference between hiring a pool and travelling to the coast. A Novice I diver would normally complete the two open-water dives as soon as possible, but if this were not possible straight away (perhaps over winter) they would at least have a specific grade within the club. The lengthy and club-oriented Novice syllabus was replaced with the Club Diver and Ocean Diver syllabuses in the late 1990s. (However, some argue the Novice description was usefully accurate and aided diver safety because nobody with such a qualification would attempt dives beyond their capabilities).

* Club Diver: This is more or less the same as Ocean Diver; originally the two were operated in parallel with Ocean Diver awarded at schools and Club Diver at clubs.
* Club Instructor: An instructor grade junior to Open Water Instructor, but allowing the holder to instruct practical and theory lessons without supervision.
* Third Class Diver: This was the entry-level grade prior to the splitting of its syllabus during the mid-1980s to create the Novice and Sports Diver grades. Divers who held this grade at the time were awarded the Sports Diver grade.[25]
* Second Class Diver: This was the immediate grade prior to the splitting of its syllabus during the mid-1980s to create the Dive Leader and Advanced Diver grades. Divers who held this grade at the time were awarded the Advanced Diver grade.[26]

## Notes

[edit]

1. ^ Discovery Diver is an intermediary course designed to ease people into diving at a slower pace. There is no requirement to have Discovery Diver before undertaking Ocean Diver.
2. ^ Advanced Ocean Diver is an intermediary course designed to held bridge the skill gap between Ocean Diver and Sports Diver. There is no requirement to have Advanced Ocean Diver before undertaking Sports Diver, though the Advanced Ocean Diver to Sports Diver[19] course exists for those who have taken Advanced Ocean Diver to qualify them as Sports Divers without repeating skils covered in Advanced Ocean Diver not present in Ocean Diver but required for Sports Diver.
3. ^ The Dolphin Snorkeller course is an intermediary course designed for children. It contains the practical elements of Snorkel Diver without any of the classroom theory.
4. ^ a b Basic Life Support is not a diving course and can be obtained outside of driving. Sufficient Basic Life Support skills are acquired via BSAC's Sports Diver courses or higher.
5. ^ In collaboration with the Royal National Lifeboat Institution
