Open Water attempts are those attempts carried
out in a body of water which allows for an uninterrupted trajectory
throughout the whole dive, which means that no turns are allowed.
These attempts may take place in either a Salt or Fresh Water
location, and F.R.E.E. recognizes this category as a single
category, regardless of the composition of the water.
- The Freediver must keep at least his/her face submerged
in the water throughout the dive.
- The Freediver must swim at a depth always shallower than
the Guide-Line.
- This is the line that runs along the intended trajectory
of the Freediver, from the Zero (0) mark to the Goal-Depth
or Goal-Length.
- The line must be of constant length and material, thickness
is not a factor.
- The Judges must inspect and certify the suitability of
the line no later than twenty-four (24) hours before the attempt.
The Judges must also measure the line and assign the Zero
(0) and Goal-Depth or Goal-Length marks no later than one
(1) hour before the departure to the site of the attempt.
- The Supervising Officer must be present during all these
procedures and F.R.E.E also recommends the Freediver to be
present during this procedure.
- For the measuring procedure, the Judges must first completely
soak the line in water for a minimum of twenty (20) minutes
and then stretch the line until it reaches a tension equal
to the amount of Bottom Ballast that will be attached to it.
After this point, the line remains under the custody of the
Judges, and until the time when the line is to be laid into
the water.
- The Zero (0) mark on the line must be leveled with the
surface of the water or below it, but never above it.
- The line can be attached to a fixed structure or a floating
device.
- The line must remain straight throughout the duration of
the attempt and its maximum allowable angle of inclination
is fifteen (15) degrees.
- The Guide-Line must be placed at a depth no deeper than
3 meters/9.84 feet from the surface and this depth must be
kept constant over the whole length of the line.
The judges
must measure the line and attach the confirmation tags to
it once the line has been laid in the water, to provide the
most accurate and fair measuring. If Scuba equipment is needed
by the judges to perform this duty, the Organizing Committee
must provide it.
- This is the ballast that attaches to the end of the Guide-Line
with the aim of keeping the line straight throughout the attempt.
- The ballast must be placed at least five (5) meters/ 15
feet below the Confirmation Signals or Bottom Plate.
- The ballast must signal the end of the Guide-Line and it
must be positioned no farther than five (5) meters/ 15 feet
from the bottom of the site. In the case the inherent conditions
of the chosen site prevent this guideline from being followed,
the Judges and the organizing Committee can agree on the use
of a site where the distance between the Bottom Ballast and
the bottom of the site varies from the above specified.
- The minimum required amount of weight for the Bottom Ballast
is 0.7 kilograms/ 1.54 pounds for one (1) meter/ 3.28 feet
of line, from the Zero (0) mark to the Goal Depth.
