Range anxiety is just missing information. Pick your boat — or type your waterline length and displacement — and see the real relationship between power, speed and range for your hull. The curve bends hard: that’s physics, not pessimism, and it’s exactly why a quiet 3 knots costs almost nothing while hull speed costs everything.
The honest curve: power grows with the cube of speed — the last knot costs more than the first three. Estimates come from the Radical Flux general propulsion model (validated on the FY25 1,000 NM trial) with a reference bank of 12 × 170 Ah × 12.5 V and a 60% usable “balanced” budget. These are planning estimates for a first conversation, not quotes — every hull, prop and installation differs, and we size conservatively before we spec.
