Mares Avanti Quattro Power: complete review and analysis (2026).

In tropical coastal currents where reef passages require constant fin power to navigate safely, the length and responsiveness of the blade provide a guarantee of serenity. The Italian manufacturer Mares offers with the Avanti Quattro Power a long-blade version of its legendary four-channel fin. We rigorously analyze its hydrodynamic structure to advise you.

This detailed evaluation report is based on our documentary analysis conducted on August 6, 2026. Our ranking system maintains its neutrality, and no affiliated links are active on our website.

To analyze the effectiveness of this standardized reinforced shoe design, we examine five evaluation criteria with equal weighting. No field tests were conducted by us for this particular pair. This overall score of 4.15 out of 5 represents its theoretical design quality but does not guarantee individual comfort.

The Mares Avanti Quattro Power is a high-performance fin with a shoe design, intended for recreational scuba diving and sporty snorkeling in warm water. Its enveloping shoe is designed for divers who seek a direct connection with the blade.

Its long sail provides excellent propulsion in areas with currents. However, the shoe size limits its use for diving in cold water that requires insulated booties.

The fin incorporates four "Channel Thrust" channels made of Techralene material and massive rubber side rails to channel the flow of water. This profile provides an excellent "flutter kick" propulsion with powerful thrust.

Imagine a track cyclist on a monocoque bike where the bottom bracket has been reinforced with carbon fiber plates to prevent twisting during sprints. This heavy reinforcement allows every watt of power generated to be transmitted without deviation. This is the advantage of this long fin, which features thick rubber ribs that stiffen the sides to optimize power transfer. The frog kick and back kick styles remain very good.

The ergonomic, soft rubber bootie snugly wraps the foot without generating painful friction during acceleration. The transfer of force between the leg and the blade is immediate.

Muscle fatigue may appear more quickly than with a softer model due to the length of the blade. This model is ideally worn barefoot or with thin neoprene socks.

The construction combines a flexible, nerve-like material for the blade and dense elastomers for the foot pocket and reinforcing ribs. The fin has neutral buoyancy in seawater to maintain horizontal balance.

These high-quality plastic and rubber components can withstand prolonged exposure to salt and sunlight without any issues. The rubber rails effectively protect the sail from deformation.

The rubber side panels protect the blade from impacts with rocks and reduce the risk of accidental breakage. The one-piece, boot-compatible design is very durable.

The sole provides reassuring grip on wet rocks and the smooth surfaces of boats. The absence of straps eliminates the main traditional mechanical failure point of this type of equipment.

The table below classifies the suitability of the Mares Avanti Quattro Power based on your profile:

The Mares Avanti Quattro Power is an excellent choice of fin for dynamic divers looking for a strong propulsion in warm water. Its comfortable boot and long, robust blade justify its very good rating.
