Lost F1 Surfboard: The Formula 1 Squash
The Lost Surfboards Formula 1 Squash is one of the most talked-about high-performance shortboards of 2025 and 2026, built off Cole Houshmand's personal WCT competition boards and adapted for everyday surfers who want that same explosive, front-foot speed and sharp, driving turns. This is the squash-tail variant of the F1 family, a deliberate design choice that opens the shape up to a broader range of wave types without sacrificing the responsiveness that made the original model famous.
Outline, Rocker, and Tail Design
The Formula 1 Squash carries a refined performance outline with pulled-in rails through the chest and a progressively fuller mid-section that feeds into a squash tail. The squash tail adds surface area right where you need it most, giving the board a livelier feel in weaker, slower surf while still locking in confidently on steeper, more powerful faces. The tail outline is one of the most versatile choices in performance shortboarding: tight enough to release cleanly through a snap, wide enough to generate its own drive out of a bottom turn.
Rocker on the F1 Squash is dialed for speed without sacrificing projection. The entry is relatively flat to pick up waves early and generate paddle power, transitioning into a controlled flip through the back third that allows the tail to release predictably at the top of the wave. The result is a board that feels quick and connected rather than stiff or skatey.
Bottom Contour and Foil
The bottom contour runs a single concave through the entry that transitions into a double concave through the fins. This classic high-performance configuration channels water beneath the board to accelerate speed through the flats and increases lift under the front foot on the face. The double through the tail separates water flow around the fins cleanly, helping each turn feel responsive and committed rather than bogged down. The foil is refined through the nose to keep swing weight down and improve rail-to-rail transitions.
Fin Configuration and Feel
The Formula 1 Squash is set up as a thruster. The three-fin thruster configuration is the benchmark for controlled high-performance surfing: it drives down the line with authority, pivots cleanly off the back foot on snaps, and tracks through drawn-out carves without washing. For a board built around competition-level precision, thruster is the logical choice. The fin box system lets you dial in your preferred fins through the variant selector on this page.
Who Is the Lost F1 Squash For?
The F1 Squash is a performance shortboard. It rewards surfers with a solid foundation of rail surfing and the ability to generate their own speed through turns. Intermediate surfers who are actively progressing their repertoire, and experienced surfers looking for a competition-oriented daily driver, will find the most in this shape. It is not a high-volume paddle machine for beginners, but it is not an elite-only specialist either: the squash tail and the fuller mid-section mean it responds well across a range of wave quality, not just on perfect days.
The shape shines in beach break conditions from knee-high to overhead, punchy reef sessions, and small-to-medium point surf where speed and sharp turns are the priority. Surfers looking for a single board that handles summer slop with the same enthusiasm as a solid winter swell will find the squash tail geometry especially useful.
Construction and Feel in the Water
Lost builds the Formula 1 Squash with their standard performance construction. The board feels lively and responsive under foot rather than stiff, with enough flex through the tail to give turns a natural, springy drive. The glass job is clean and the finish is consistent with what you would expect from a brand that has been supplying professional-level surfboards since the early 1990s. The white deck with red stringer keeps weight low and performance focus high.
Lost Surfboards Heritage
Lost Surfboards, shaped by Matt "Mayhem" Biolos out of San Clemente, California, has shaped boards for some of the most decorated surfers in WCT history. The Formula 1 program represents a direct pipeline from Houshmand's winning competition boards to the production line, with minimal compromise between what works in a contest heat and what works in everyday surf. When you ride an F1 Squash, you are riding a board whose lineage runs directly through a WCT event win.

Frequently Asked Questions
- What is the Lost F1 surfboard?
- The Lost F1 (Formula 1) is a high-performance shortboard designed by Matt Biolos of Lost Surfboards, based directly on Cole Houshmand's WCT competition boards. The F1 Squash is the squash-tail variant of that design, adapted for a wider range of everyday wave conditions while keeping the same contest-ready speed and precision.
- Is the Lost Formula 1 Squash good for intermediate surfers?
- The F1 Squash rewards surfers who can generate their own speed and drive through turns. Solid intermediate surfers who are actively progressing their rail surfing will get a lot out of this shape. The squash tail and the fuller mid-section make it more forgiving in weaker surf than a pure competition narrowboard, but it is not designed as a beginner board.
- What wave types does the Lost F1 Squash work best in?
- The Formula 1 Squash performs from small, punchy beach break up through overhead surf. The squash tail adds surface area that keeps the board lively in softer, mushier conditions, while the refined rocker and concave system hold in on steeper, more powerful waves. It is a versatile everyday shortboard for surfers who want one board across a range of South Florida conditions.
- What size Lost F1 Squash should I ride?
- Size selection depends on your weight, fitness level, and the wave conditions you surf most often. As a general rule, performance shortboard surfers ride a volume that falls between 35 and 40 percent of their body weight in kilograms, but that range shifts depending on your skill level and how much paddle power you want. Check the size chart on this page for the full dimensions at each length, and call us at 954-427-4929 if you want a recommendation based on your specific situation.
- What is the difference between the Lost F1 Squash and the Lost F1 Round tail?
- The Formula 1 Round and Formula 1 Squash share the same core rocker and concave system derived from Cole Houshmand's competition boards. The key difference is the tail shape. The squash tail adds width and surface area in the tail block, which increases drive, speed, and function in weaker or smaller surf. The round tail releases more freely and suits surfers who prioritize pivot and flow on steeper, more powerful waves. Both are thruster setups. Use the variant selector on this page to choose your size.
- Does the Lost F1 Squash come as a thruster or quad?
- The Formula 1 Squash is configured as a thruster (three-fin setup). The thruster delivers the controlled drive and precise pivot that makes this shape work so well for competition-oriented surfing and high-performance turns. The fin box system is compatible with the fin brand of your choice.
- What is the Lost F1 Squash review verdict from surfers?
- Surfers who ride the Lost F1 Squash consistently note its fast, front-foot feel, quick rail-to-rail response, and the way it stays engaged in weaker surf without losing control in better waves. The squash tail gets particular praise for versatility. For a detailed conversation about how it compares to your current board, contact the Island Water Sports team at 954-427-4929.
