Oar Length Calculator

This calculator estimates optimal oar length for rowing based on your boat dimensions and rowing style

Input Parameters

Typical range: 60-100 cm based on boat type and rower

Calculation Results

Estimated Oar Length

Standard Oar Length: -- cm

Tiller Extension Adjustment: -- cm

Recommended Oar Length: -- cm

Calculation Formula

L = √(B × E) + E + T

Where:
L = Oar Length (cm)
B = Boat Beam (meters)
E = Effective Rowing Height (cm)
T = Tiller Extension (cm) - varies by oar type

Oar Length Calculator Usage Guide

Learn how to use the Oar Length Calculator and understand the factors affecting oar length

How to Use This Calculator

  1. Enter your boat's length in meters (overall length)
  2. Enter your boat's beam (width) in meters at the widest point
  3. Select the appropriate oar type from the dropdown menu:
    • Coastal Rowing: For smaller boats in coastal conditions
    • Racing: For competitive rowing with longer oars
    • Sea Rowing: For open water rowing (default option)
    • Light Rowing: For recreational rowing with moderate oar length
  4. Adjust the effective rowing height if needed (typically 80cm, but can vary)
  5. Click the "Calculate" button to see your recommended oar length

Understanding Oar Length Factors

Oar length is crucial for efficient rowing and depends on several factors:

  • Boat Length and Beam: Longer boats generally require longer oars
  • Oar Type: Different rowing disciplines use different oar lengths
  • Rowing Style: Heavier crews might need longer oars for better leverage
  • Rower Height: Taller rowers may need longer oars for proper reach

Important Considerations

This calculator provides an estimate based on standard formulas. For precise oar length selection, consider:

  • Trying different lengths in your boat
  • Considering your rowing stroke style
  • Checking with experienced rowers or coaches
  • Measuring your actual stroke length for more precise results
