Constant weight without fins

Constant Weight Without Fins (CWWF) is a discipline in freediving, where the diver descends and ascends using only their own physical strength, without the use of fins or any other propulsion equipment. This discipline is recognized by the International Association for the Development of Apnea (AIDA) and is one of the most challenging and purest forms of freediving.

Overview

In CWWF, the diver descends and ascends along a guide rope, without pulling on the rope or using any other means of propulsion such as fins or sleds. The diver can only use their arms and legs to swim down and back up. The depth reached by the diver is measured and the diver is ranked based on this depth. The use of a dive computer or depth gauge is mandatory in this discipline to ensure safety and accurate measurement of depth.

Technique

The technique used in CWWF is crucial to the success of the dive. The diver must have a strong swimming technique and be able to maintain a streamlined position in the water to reduce drag. The diver must also have a strong breath-holding technique to be able to stay underwater for the duration of the dive. The diver must also be able to equalize their ears and sinuses as they descend to prevent barotrauma.

Training

Training for CWWF involves improving swimming technique, breath-holding ability, and physical strength. It also involves learning to manage the physiological and psychological challenges of diving to great depths without the aid of propulsion equipment. Training often involves pool training, depth training, and dry training exercises.

Safety

Safety is a paramount concern in CWWF. Divers must be accompanied by a safety diver who can provide assistance in case of an emergency. Divers must also be aware of the signs of hypoxia and decompression sickness, and know how to respond to these conditions.

Records

The world records for CWWF are held by the AIDA and are recognized as the deepest dives without the use of fins. The current men's and women's world records are held by Alexey Molchanov and Natalia Molchanova, respectively.
