Where it fits
It fits surfers who want fish-derived speed with a more performance-focused direction than a purely traditional twin-fin fish.

Performance Fish
The Lost RNF 96 is indexed as a performance fish with twin-plus-trailer and five-fin setup records.
An exact manufacturer page for this model was not confirmed, so Quivrr has not presented the available variant source as an exact match.
It fits surfers who want fish-derived speed with a more performance-focused direction than a purely traditional twin-fin fish.
Its moderate paddle-support and forgiveness scores keep it between an easy retro fish and a technical conventional shortboard.
The performance-fish classification suits everyday waves where speed matters but the surfer still wants directional control and shortboard influence.
Compared with the Firewire Seaside, the RNF 96 offers a more explicitly performance-fish lane and broader fin configuration choices.
