Product Information
The Seac Motus Carbon Fin Blade is an interchangeable replacement blade for Seac's Motus freediving and spearfishing fin system, built from unidirectional pre-preg carbon fiber for a lighter, more reactive kick than Seac's standard thermoplastic Motus blades. It mounts to the Motus foot pocket at the same fixed 22-degree blade-to-foot-pocket angle used across the entire Motus line, and is sold as a single replacement blade.
Who it is for
This blade suits freedivers and spearfishers using a Seac Motus foot pocket who want a lighter, more reactive carbon blade. It also works for divers who need a spare or replacement blade for an existing Motus fin, since Seac designed the Motus system so the blade and foot pocket can be swapped independently.
Key details
- Blade material: unidirectional 100% pre-preg carbon fiber, pre-impregnated without glass fibers
- Internal reinforcement: carbon weave set at 45 degrees
- Made in France
- Fixed blade angle: 22 degrees between the blade and the foot pocket
- Seac describes the carbon construction as "ultra light, high performance"
Compatibility and sizing
This Motus Carbon blade is built to attach only to the Seac Motus thermoplastic foot pocket. It is not sold with a foot pocket; it replaces the blade portion of an existing Motus fin or lets a current Motus owner switch from thermoplastic to carbon.
What's in the box
- 1 replacement fin blade

Frequently Asked Questions
Does the Seac Motus Carbon blade fit any fin foot pocket?
No. The Motus Carbon blade attaches to the Seac Motus thermoplastic foot pocket as part of Seac's interchangeable blade system.
What makes the carbon blade different from Seac's standard Motus blade?
The carbon version uses unidirectional 100% pre-preg carbon fiber with an internal 45-degree carbon weave reinforcement, made in France, instead of the thermoplastic material used on standard Motus color blades. Seac describes it as ultra light and high performance, giving a more reactive kick at the same 22-degree blade angle.
Do I need to buy a new foot pocket to use this blade?
No. This listing is for the replacement blade only; it is designed to attach to an existing Seac Motus foot pocket. If you already own a Motus fin, you can swap the blade without replacing the foot pocket.
What angle is the Motus Carbon blade set at?
The blade mounts at a fixed 22-degree angle relative to the foot pocket, the same angle used across the Seac Motus fin line.
