Cetma Composites continues to push the limits of polymer-blade fins with the new Cetma Lotus HD, the latest evolution of the already successful Lotus polymer blade fins presented in our X-Rays column and tested by Davide Tummolillo. Designed and manufactured entirely in Italy through in-house engineering, research and production, the new Lotus HD aims to further improve performance, responsiveness and reliability for demanding spearfishermen and freedivers.
From the Revolutionary Lotus to the new HD Version
The original Cetma Lotus fins represented a true revolution in the world of plastic-blade freediving fins. At a time when traditional polymer fins still offered limited efficiency compared to carbon solutions, the Lotus introduced innovative engineering concepts that changed the market.
One key element was the revolutionary Cetma S-Wing foot pocket, among the first to be developed using advanced engineering and fluid-dynamics concepts. The goal was clear: optimize energy transfer, comfort and hydrodynamic efficiency.
At the same time, the Lotus polymer blade itself delivered performance levels that were significantly superior to traditional plastic fins, approaching sensations and efficiency previously associated mainly with composite blades.
Today, Cetma Composites has taken another important step forward.
New Polymer Compound Developed In-House
Building on the consolidated success of the Lotus line in polymer micro-composite material, Cetma Composites listened carefully to the needs of professional athletes and passionate users to develop an even more advanced solution.
Both the Lotus LS and the new Lotus HD now feature an updated and optimized polymer blend, developed entirely through Cetma’s in-house engineering research. The Italian company has focused heavily on polymer science to improve both mechanical efficiency and long-term reliability.
The result is a blade with improved responsiveness, enhanced durability and more efficient energy return compared to the previous generation.
This is a key aspect because polymer fins are often chosen not only for affordability, but also for robustness, versatility and reliability in difficult conditions.
Lotus HD: More Power for Demanding Conditions
The new Lotus HD version joins the existing Lotus LS model, but introduces a stiffer setup specifically designed for more demanding use.
While the LS remains slightly softer and more progressive, the HD version is aimed at spearfishermen and freedivers who require additional thrust and more immediate response.
The stiffer blade structure becomes especially useful:
- in strong current
- in rough sea conditions
- during fast accelerations
- for powerful surface swimming
- during demanding deep dives
The new micro-composite polymer formula further enhances power transmission, offering a highly reactive feeling during finning.
According to Cetma Composites, the Lotus HD is not simply a harder fin, but a completely optimized solution designed to maximize reactivity, control and propulsion efficiency.
Designed for Spearfishing and Deep Freediving
The target users of the Cetma Lotus HD are clearly advanced spearfishermen and performance-oriented freedivers.
Spearfishermen will appreciate:
- fast acceleration
- precise maneuverability
- stronger propulsion against current and waves
- excellent control during surface swimming
Freedivers will benefit from:
- powerful ascent support
- efficient energy transfer
- high reactivity during dynamic finning
The result is a versatile fin capable of adapting to very technical conditions.
Aggressive Look and Full Size Availability
Visually, the Lotus HD immediately stands out thanks to its bright red blade combined with the black Cetma Composites logo, creating an aggressive and performance-oriented design.
The Cetma S-Wing foot pocket is available in a very extensive size range, from 35-36 up to 47-48, making the fins suitable for both women and men with virtually complete coverage of the market.
As with all major Cetma products, the entire process — engineering, design, research, development and production — is carried out internally in Italy, reinforcing the company’s strong engineering identity and manufacturing philosophy.
Cetma Composites continues its engineering path
Cetma Composites has always differentiated itself through a strong engineering-driven approach to product development, with extensive internal know-how in composites, polymers and hydrodynamics.
The new Lotus HD perfectly reflects this philosophy: not simply a cosmetic update, but a concrete technical evolution developed through material research and real performance objectives.
For divers looking for the practicality and durability of polymer fins without sacrificing advanced performance, the Cetma Lotus HD could become one of the most interesting solutions currently available on the market.
