About the brand

The SIEVE story started a few years ago on a beach in Denmark. Sebastian was inspired by a desire to combat ocean plastic and began collecting washed-up plastic. He envisioned crafting his own surfing equipment, specifically surf fins, from recycled plastic to prevent plastic from reaching the oceans. This idea aimed to provide a sustainable alternative to traditional surf fins and promote responsible plastic use.

SIEVE is a collaborative effort of a diverse team with a passion for the ocean and surfing. Their mission is to create sustainable surf fins made from recycled materials, while adhering to key principles such as recycling, local production, and circular products. SIEVE firmly believes that sustainability should never compromise quality. SIEVE Fins is committed to both environmental responsibility and top-notch product standards.

FUTURES Thruster Fin Set VECTOR 3/2 L Alpha

WHAT IS A VECTOR FOILVector is a proprietary Futures foil featuring a concave surface on the inside of the front fins. Specifically in the Vector, the concave runs from the base to the tip of the fin, increasing water attachment and lift.WHAT IS A 3/23/2 is a complement to the Vector foil, where the top half of the fin has an additional 3 degrees of cant and 2 degrees of toe. There is a noticeable twist to the foil, changing the planing angle in the turn at sharper angles of attack, creating lift and hold further into the turn.PERFORMANCE BENEFITS OF THE VECTOR 3/2The Vector 3/2 is an amplified Speed Generating fin, as a result of maximum water attachment, over multiple planing surfaces, creating lift and reducing drag. The combined effects of the concave surface area, from base to tip, and the twist in the upper half of the fin net a uniquely positive sensation of grip and projection. In smaller waves, the feeling of speed generation is fluid and obvious. As the surf increases, the water attachment and additional lift properties provide powerful connection in turns and increased speed from one to the next, resulting in faster surfing and better turns.BENEFITS OF THE SCIMITAR TIPThe Scimitar Tip is the flattened edge of the tip on the trailing edge of the fin. By reducing the length of the template, we’re affecting the amount of hold the fin will have. The 3/2 foil is designed to create lift and speed, so the surface area in the tip has been reduced to tighten up the turn arc, as a compliment to the 3/2 foil. This template features a lot of surface area in the base, maximizing the potential of the foil properties through the body of the fin, finishing with this final tip enhancement to achieve the desired feeling of release from the turn.SCIMITAR TIPs a final component to the overall Vector 3/2 set, the center fin template has been specifically designed to provide thrust into turns, while reducing drag and shortening the turn arc. The specific adjustment comes in the tip area, with a more refined Scimitar shape that is narrower than the side fins and has just a touch more rake. The trailing edge has a deeper inward curve, elongating the upper half of the fin for a touch more flex. While aesthetically similar to the side template, the refined center fin adds the perfect amount of response to complement the engineered elements of the Vector 3/2 foil on the side fins.Template Category - Neutral (all-around, versatile)Construction - AlphaSpeed GeneratingSuggested Wave Type - All types, All conditionsSize - Medium (55 – 80 kg)Content: 3 Fins

ROAM Footpad ECO Algae Traction Pad 3-piece - Black

Algae foams are environmentally conscious replacements for traditional petroleum based EVAs. Algae foam contributes two fold to the environment - the source material is algae removed from water ways to improve the quality of the eco-system and re-circulate fresh water. The foam derived from Algae replaces the traditional EVA foam used in pads which is an oil based foam, so less oil is used in making Algae based traction pads. The Algae Foam pad is based on our best selling 3 piece pad, designed for most surfboard shapes. The ROAM surfboard Pad in a cool design provides great grip on your Surfboard, Skimboard, SKiteboard, SUP. The Tailpad has a Tailkick that allows more pressure on the surfboard tail. The ROAM Pad surface is grooved in a special Diamond grooving and sanded and stays sticky and grippy in any kind of water or condition. Original 3M PSA (PSA) insures that your pad will never pull off until you take it off. 3 piece Grip 5mm middle Arch25mm Kick TailDiamond groovingApp 29cm wide x 30cm high3M Marine Grade adhesive (selfadhesive)

Customer questions

What is a Fin cant?

The Fin cant refers to the angle at which the fin is positioned on the board. A straight-on position (0 degrees cant) optimizes fast straight-line driving but compromises responsiveness in turns. A larger angle (cant) enhances drive in turns, providing a balance between speed and maneuverabilit

What is the Foil in a fin?

Similar to the aerodynamic shape of airplane wings, surfboard fins have a foil – a tapered design that varies from thick at the center to flatter at the edges. This 'bulbous' shape provides lift and influences the board's performance. The fin foil differs based on the type of fin (single, twin, thruster), with side fins often having a flat or slightly inward-curved profile. Center fins typically feature a symmetrical or 50/50 foil on both sides. The diverse foil designs cater to different surfing styles and board configurations.

What is the significance of Rake and Sweep in surfboard fins?

Rake and Sweep play a crucial role in surfboard fin design. Rake refers to the length of the leading edge, while Sweep is the angle from the base center to the highest point. A smaller rake, with a shorter leading edge, offers stability and a straight appearance, limiting pivot for a controlled feel. In contrast, a longer rake allows for more turns, providing a looser feel. These factors influence how well the board turns on a point. For a comprehensive guide on Rake and Sweep, check reputable online sources for detailed insights into optimizing your surfboard's performance.
