Abstract
A fin blade for free diving or swimming or scuba diving is described, which has a cross section at one end angled about a yaw, or longitudinal, axis relative to the cross section at the other end. The arrangement is such that a lateral line at a proximal end is disposed at an angle relative to a lateral line at a portion spaced from the proximal end. The fin blade is more closely aligned with the ergonomic complexities of the human body, such that during finning the fin blade provides greater comfort and/or propulsion. A fin blade is also described which includes a reinforced zone in one portion of the fin blade, such that one portion of the blade at the distal end is relatively increased in flexibility to provide a catch zone at one portion of the distal end of the fin blade.
Claims23
A fin blade suitable for free diving wherein a lateral line adjacent a proximal end of the fin blade is disposed at an angle relative to a lateral line at a portion spaced from the proximal end of the fin blade, and wherein the lateral line at the proximal end of the fin blade is elevated from one side to the other.
A fin blade for freediving, comprising:
- a flexible matrix and a reinforced zone disposed on the flexible matrix in a region proximal a foot pocket and adjacent at least a portion of an outer edge of the proximal region,
- wherein a lateral line adjacent a proximal end of the fin blade is disposed at an angle relative to a lateral line at a portion spaced from the proximal end of the fin blade, and
- wherein the lateral line at the proximal end of the fin blade is elevated from one side to the other.
A fin suitable for free diving, comprising:
- a foot receiver and a blade, the blade being configured to fit into the foot receiver,
- wherein a lateral line adjacent a proximal end of the blade is disposed at an angle relative to a lateral line at a portion spaced from the proximal end of the blade, and
- wherein the lateral line at the proximal end of the blade is elevated from one side to the other.
