Lost Rad Ripper (5'6 - 5'10) FCS Blacksheep

The Lost Rad Ripper surfboard has emerged as one of the most influential shortboard designs of the 2020s, blending nostalgic 1980s-inspired aesthetics with modern hydrodynamic refinements.

Developed by Matt "Mayhem" Biolos through Lost Surfboards, this model redefines small-wave performance with its innovative combination of retro-inspired outline, flat rocker profile, and advanced concave bottom contours. Marketed as part of the "Post Modern Retro" collection, the Rad Ripper achieves a rare balance between user-friendly accessibility and high-performance capabilities, making it equally appealing to intermediate surfers and professionals.

Origins in 1980s

The Rad Ripper directly channels the performance shortboards of the 1980s, an era when shapers experimented with radical tail shapes and rocker profiles to enhance maneuverability in critical sections.

Matt Biolos specifically cites childhood admiration for the "ease of use" characteristic of boards from this period, particularly their ability to generate speed without excessive input from the rider. 

However, the 1980s designs often suffered from excessive tail lift and inconsistent release in smaller waves, limitations that the Rad Ripper addresses through calculated modernization.

From Retro Ripper to Rad Ripper: Key Modifications

As an evolutionary development from the Retro Ripper model, the Rad Ripper incorporates three critical design adjustments:

1. Rocker Reduction: Entry rocker decreased by approximately 12-15% compared to the Retro Ripper, facilitating faster paddle acceleration and earlier wave entry.
2. Tail Redesign: Replacement of the Retro Ripper's rounded pin tail with a wide squash template (increasing planing surface area by ~18% in equivalent lengths) to improve speed retention through flat sections.
3. Concave Optimization: Aggressive double concave transitioning to vee in the tail replaces the single concave of predecessor models, creating 23% greater water displacement under the rear foot during turns.

These modifications position the Rad Ripper as a specialized small-wave tool while retaining the retro aesthetic that defines Lost's Post Modern Retro series.

LightSpeed is our proprietary surfboard construction built with lightweight EPS foam and high strength epoxy resin.  LightSpeed uses a combination of Rapid-Reflex Carbon Fiber as well vibration dampening Innegra-Fibers, woven into the finest custom performance fiberglass cloth. 

Like the name implies, LightSpeed is both light and exceptionally fast, allowing you to take your surfing to new levels of speed and Pro-formance.  Developed in-house, our crew of board builders worked closely with our top Jr and WQS team riders to create the best possible technology for High Pro-formance small wave and every day surfing. After well over a year of testing various versions, and R&D with some of the world’s best young surfers, we are now making this exciting custom surfboard construction available to all. 

Ultra-Light / Ultra-Lively Foam Core: Steam molded, High Strength-to-Weight Ratio, fused cell, water resistant, stringer-less EPS foam core.

High-Strength, Flexible, Impact Resistant, Epoxy Resin System. Woven Carbon Fiber Centerline “Stringer” (top and bottom): Engineered to add both strength and Rapid-Reflex “pop”, with just enough release to feel forgiving underfoot. The Carbon loads up under foot pressure, and springs upon release.

Fused Carbon, Tail Reinforcement Patches: Transfers more direct input into rail and adds strength.

Centerline Aligned Carbon “Exo-Stringers”: Enable natural Torsional Twist, similar to a wood stringer board, but lighter, and with a much faster reflex reaction and more “pop”.

Innegra Infused, Engineered Composite Fiberglass: A multi weave (6oz lengthwise, woven with 4oz, rail to rail) fiberglass, top and bottom, adds significant break strength, while keeping the boards Ultra-light and Ultra-lively.

5oz Warp-Weave Fiberglass: A multi weave (6oz lengthwise, woven with 4oz, rail to rail) fiberglass, top and bottom, adds significant break strength, while keeping the boards

Ultra-light and Ultra-lively.

LightSpeed – Light and exceptionally fast technology, allowing you to take your small wave and everyday surfing to new levels of speed and Pro-formance.

Matt Biolos and the team at LOST Surfboards have introduced their innovation in surfboard construction: Black Sheep Technology.

This groundbreaking approach to carbon fiber construction delivers an electric, lively feel while maintaining durability and performance.

The defining feature of Black Sheep boards is their unique tri-directional carbon fiber deck wrap. Unlike traditional carbon constructions, this specialized layup uses three distinct directional layers: one running nose to tail and two at opposing 45-degree angles. This configuration creates a responsive flex pattern while preventing the board from becoming too stiff.

"We wanted to make a really pliable, forgiving, lively kind of playful construction," explains Biolos. The construction keeps carbon only on the deck, stopping at the rails to maintain torsional flex and prevent the board from becoming overly rigid.

Each Black Sheep board features:

• 1.5-pound EPS core
• Double-layered fiberglass bottom
• Tri-directional carbon fiber deck
• Non-crimp weave technology for optimal strength

The result? A lightweight, responsive board that maintains durability while delivering performance in various conditions. Pro surfers are already embracing the technology, with extensive testing at wave pools and in ocean conditions showing promising results.
