Lost RNF Retro Revamp (5'2-5'4) Double Dart

The Lost RNF Retro Revamp is a 1970s-inspired performance fish built around a dual side-cut outline that lets a flat-rockered board carve tighter and harder than most fish have any right to. If you want drive, speed, and the ability to actually turn — this is the fish that delivers all three.

Key Advantages

🏄‍♂️ Effortless Wave Catching - Generous dimensions, low rocker, flat deck, and wide tail make catching waves easier than any fish Lost ever designed

⚡ Explosive Down-the-Line Speed - Delivers lots of driving speed down the line, especially in small and soft surf conditions

🎯 Revolutionary Dual Side-Cut System - Snowboard-inspired reverse radius side-cut enables sharp turns while retaining speed in tight radius maneuvers

💪 Enhanced Carbon Construction - Double Dart construction with carbon fiber shell provides strength and torsional flex for enhanced performance

Perfect For You If

• You want a board that excels in clean, slopey surf ranging from knee high to overhead
• You're looking for a modern take on a classic 1970s-inspired fish design
• You surf small and soft surf conditions and want maximum driving speed
• You appreciate innovative design that stands apart from typical fish offerings
• You want easy wave-catching abilities with smooth cruising speed through big carving turns

Technology Behind the Magic

The RNF Retro Revamp features Double Dart Construction, incorporating a carbon fiber shell on both the top and bottom of the board. This construction provides strength and torsional flex, allowing the board to bend and twist more freely without becoming too rigid or stiff, offering a unique surfing experience and enhancing the board's overall performance.

Revolutionary Side-Cut Technology: What sets the RNF Retro Revamp apart from endless schools of fish is the use of a snowboard-inspired design element - reverse radius side-cut in the outline. The RNF Retro uses not one, but two side-cut radiuses: one between the feet, starting just behind the wide point, and another shorter/tighter one right under the rear foot, in place of a hip or wing. This outline enables a flat rockered and generally parallel outlined board to turn sharper and retain speed in tight radius turns. They "lock in" to the wave face and carve off the rail without sliding out or digging.

The RNF Retro Revamp pays homage to the low-rocker, high-performance longboards that dominated the surf scene during the sport's golden era, featuring generous dimensions, low rocker, flat deck, steep rails, and wide tail.

Fin Setup Options

The RNF Retro Revamp is built for surfers who want more out of a fish than just straight-line glide.

• Intermediate to advanced surfers ready to bring real performance to a fish template
• Lighter, shorter riders who want a shorter board with high volume and easy entry
• Heavier riders who like the idea of a fish but need something that responds to back-foot pressure
• Surfers transitioning off a hybrid or shortboard who want glide without giving up turning ability
• Anyone who's ridden the original RNF Retro and wants the refined, more precise version

This board rewards surfers who know how to drive off the back foot and engage a rail — it's not just a cruiser, it's a fish with serious performance potential.

The RNF Retro Revamp performs best in clean, open-face waves with room to build speed and carve — knee-high to well overhead. The dual side-cut outline really comes alive when the wave has some shape and slope to it. On a day when your shortboard feels like work, this board turns the same session into something fast and fun. It handles Hawaii's variable surf well — softer days, punchy beach break, and even shoulder-high days with open walls all sit in its wheelhouse.

The defining feature of the Revamp is the dual side-cut outline — two separate reverse-radius sidecuts borrowed from snowboard design. One runs between the feet starting just behind the wide point; the second, tighter sidecut sits right under the back foot in place of a traditional hip or wing. Together, they let this flat-rockered, wide-tailed board lock into the wave face and carve sharp turns without sliding out or catching rail. The Revamp refines the original RNF Retro with a forward-shifted wide point, a slightly pulled-in nose, a deepened rear sidecut, and a hint of extra tail width for horizontal trim. The rocker was also reworked front and back — flatter in the forward third for faster entry, and a low-hanging tail rocker that sweeps up quickly through the fin area, creating more curve under the back foot without adding rocker tip-to-tail. Foil thickness was pushed forward to match.

Double Dart construction wraps the board in a full carbon fiber shell on both deck and bottom, providing structural strength and torsional flex. The board bends and twists more freely than a standard epoxy build — reactive underfoot, fast rail-to-rail, and lively through turns.
