Product Information
The SEAC BM30 Composite Blade is a short-blade fin built around SEAC's FRC (Fully Responsive Compound) technopolymer, a material developed to reproduce the elastic response of carbon and glass fiber blades without their fragility, with the blade set at a 30 degree angle and small stabilizing fins at the tip to stop lateral drift. It is made 100% in Italy at SEAC's solar-powered facility in San Colombano Certenoli.
Who it is for
These fins suit scuba divers and freediving enthusiasts who want a compact, reactive blade rather than a long carbon one. The 30 degree blade angle follows the natural inclination of the ankle and helps with surface finning, while the ergonomic foot pocket geometry is aimed at comfort over longer dives. Because the blade delivers quick response and efficient propulsion without being fragile, it works for beginners learning kick technique as well as experienced divers who want agility and control.
Key details
- Blade: FRC technopolymer, ultra-thin and differentiated in profile for optimal flexion, with no reinforcing ribs or added protection needed.
- Blade angle: 30 degrees.
- Stability: small stabilizing fins at the end of the blade, where water flow is greatest, plus short water rails that optimize technopolymer reactivity.
- Foot pocket: dual-material build, a stiffer compound in the sole for stability and a softer compound in the upper for comfort.
- Durability: high resilience, yield and tear strength, with shape memory that returns the blade to its original geometry even after being rolled up, and no risk of permanent deformation at low temperatures.
- Materials: free of toxic elements and with a reduced carbon footprint compared with common industry technopolymers.
Compatibility and sizing
Offered here in Black/Blue and Black/Green, in US sizes 3-3.5, 4.5-5.5, 6.5-7, 8-8.5, 9.5-10, 11-12 and 12.5-13.5. The BM30 foot pocket is also compatible with other SEAC fin lines such as the Shout series.

- FRC technopolymer blade Fully Responsive Compound material engineered to deliver carbon-fiber-like elastic response without the fragility.
- 30 degree blade angle Follows the natural inclination of the ankle and aids surface finning.
- Ultra-thin differentiated profile Thinner than previous technopolymer blades thanks to the material's fluidity and specific weight, for optimal flexion.
- Tip stabilizers Small stabilizing fins at the end of the blade, at the point of greatest water flow, prevent sideways drift.
- Short water rails Channel water while keeping the technopolymer's reactivity intact.
- No reinforcing ribs needed Blade geometry exploits carbon and glass-fiber-like performance without added ribs or protection.
- Dual-material foot pocket Stiffer sole compound for stability paired with a softer upper compound for comfort.
- Shape memory blade Returns to its original geometry even after being rolled up, with no permanent deformation.
- Cold-resistant toughness High resilience, yield and tear strength with no risk of breakage, even at low temperatures.
- Cleaner materials Reduced carbon footprint versus common industry technopolymers and a total absence of toxic elements.
- Made in Italy Produced at SEAC's solar-powered facility in San Colombano Certenoli.
- Color and size choice Black/Blue and Black/Green, US sizes 3-3.5 through 12.5-13.5.

Frequently Asked Questions
What sizes and colors are the SEAC BM30 fins available in?
This listing offers the BM30 in Black/Blue and Black/Green, in US size ranges 3-3.5, 4.5-5.5, 6.5-7, 8-8.5, 9.5-10, 11-12 and 12.5-13.5. If you are between ranges, call or chat with our Irvine, California shop and we can talk through fit.
What is FRC and how does it differ from a carbon fin blade?
FRC stands for Fully Responsive Compound, a technopolymer SEAC developed to replicate the elastic response of carbon fiber and glass composite blades without their fragility. It offers high resilience, yield and tear strength with no risk of breakage or permanent deformation, even at low temperatures. The blade even has shape memory, returning to its original geometry after being rolled up.
Does the BM30 blade need reinforcing ribs or extra protection?
No. The BM30 blade geometry is designed to exploit carbon and glass-fiber-like performance without reinforcing ribs or added protective elements. The profile is ultra-thin and differentiated in thickness for optimal flexion, and it is thinner than earlier technopolymer blades because of the FRC material's fluidity and specific weight. Short water rails and small tip stabilizers handle tracking instead.
Is the BM30 foot pocket compatible with other SEAC fins?
Yes. The BM30 foot pocket, also sold by SEAC as the Scarpetta BM30 / BM30 Carbon, is compatible with other SEAC fin lines such as the Shout series. It uses a dual-material build, with a stiffer compound in the sole for stability and a softer compound in the upper for comfort. Contact us at 888-701-4017 to confirm a specific blade pairing.
