The Lost RNF Kingfish 6'7" Surfboard is a high-volume performance fish designed for surfers who want easy wave entry, plenty of glide, and a loose, lively feel without stepping all the way into a traditional mid-length. At 6'7" x 20.88" x 2.7" with 41.5 liters, this version gives you substantial paddle power and stability while keeping the board responsive enough for drawn-out turns and faster surfing.
High-Volume Fish Performance
The RNF Kingfish is built around the idea of making a fish-style board easier to paddle and more versatile across a wider range of surf. The extra length and volume help with wave catching and speed generation, while the overall outline keeps the board feeling much more performance-oriented than a traditional cruiser.
This 6'7" size is especially appealing to surfers who want more foam underfoot without giving up the drive and maneuverability that make fish-inspired boards fun.

Thruster vs. Twin with Trailer
Running the RNF Kingfish as a thruster gives it a more planted, controlled feel with predictable turning and solid hold through the pocket. This is the better choice when you want the board to feel more balanced and familiar in stronger or more structured surf.
Switching to a twin with trailer opens the board up and gives it a faster, looser feel with more release through turns. This setup works especially well when you want to maximize speed and flow while still keeping a little extra control from the trailer fin.
Who Is the Lost RNF Kingfish 6'7" Best For?
This board is a strong choice for surfers looking for a higher-volume fish-inspired board that paddles easily and catches waves early while still offering real performance. It is especially well suited to riders who want something more forgiving than a shortboard but livelier and more maneuverable than a traditional mid-length.
