Speed Calculator
1. Wheel Size Input Propeller Input
Measure the wheel from top to bottom at the widest point, mounted and inflated. Section width is unknown in this mode, so only the diameter is drawn.
Only pitch and slip change the speed, not diameter or blades.
A displacement hull this long cannot exceed about 0 knots however much power is added. The figure below is what the propeller would deliver, not what the boat will do — it applies only to a hull that planes.
For inch-based motorcycle tyres, sidewall height is assumed equal to the tyre width, so outside diameter = rim + 2 × width.
2.Drive Input
3.Results
Gear ratio, motor speed and the wheel size all have to be above zero before a speed can be worked out.Gear ratio, motor speed and the propeller pitch all have to be above zero before a speed can be worked out.
Speed is calculated from the entered values. Tyre deformation, slip and motor load are not included.Speed is calculated from pitch, gearing and the slip you entered. Hull resistance, load and gearbox losses are not included, so this is the speed the propeller would deliver in ideal conditions.

What each propeller figure does
| Field | Unit | Changes the speed? |
|---|---|---|
| Propeller Pitch | inch / mm | Yes — directly |
| Slip | % | Yes — directly |
| Gear Ratio | : 1 | Yes — divides propeller RPM |
| Motor Speed | RPM | Yes |
| Propeller Diameter | inch | No — sets thrust and load |
| Blades | pcs | No — sets thrust and smoothness |
| Waterline Length | m | No — only checks the hull-speed ceiling |
Why pitch and not diameter
A wheel travels one circumference per turn. A propeller travels its pitch — the distance it would advance through solid water in one revolution. Diameter decides how much water the blades can push, which is thrust; it does not change how far one turn carries the boat.
Why slip matters
Water is not solid, so the propeller always advances less than its pitch. That shortfall is slip, and ignoring it overstates the speed by 10–45%. Pick the hull type to load a typical figure, then adjust it if you know your own.
| Hull | Typical slip |
|---|---|
| Displacement / heavy | 25–45% |
| Semi-displacement | 18–25% |
| Planing, matched prop | 10–15% |
| Racing | 5–10% |
The formula
speed = pitch × (motor RPM / gear ratio) × (1 − slip)
Hull-speed ceiling
A hull that does not plane cannot outrun its own bow wave, whatever the propeller delivers. That ceiling is about 2.43 × √(waterline length in metres) knots. Enter the waterline length and the calculator will warn you when the propeller figure passes it.

9,548.8 × Power (kW) / Speed (RPM) = Torque (N.m)
63,025 × Power (HP) / Speed (RPM) = Torque (lb.in)
Torque (N.m) × Speed (RPM) / 9,548.8 = Power (kW)
Torque (lb.in) × Speed (RPM) / 63,025 = Power (HP)
