🪁 Windsurfing Gear Selector

Choose the right sail size and board volume for your session using wind speed, rider weight, and skill level.

Typical planing range: 12–35 knots.

Recommended Sail Size

5.5

Typical range: 5.0–6.5 m²

Board Volume

130 L

Adjust for wave boards (-10 L) or freeride (+10 L)

Carry multiple sails (±0.5–1.0 m²) to adapt to changing wind. Heavier riders or gusty spots may need slightly larger gear; lighter riders can size down.

How to Use This Calculator

1

Input wind speed & level

Use forecast or on-spot measurements to gauge the conditions.

2

Select your weight & experience

Weight impacts sail power; skill level dictates board volume and sail control.

3

Review sail & board recommendations

Use results as a baseline for your quiver selection.

4

Adjust for style & spot

Freeriders, wave sailors, and freestyle riders may adjust board/sail sizes accordingly.

Formula

Sail Size ≈ Base × Weight Factor × Experience × Wind Adjustment

Empirical rule-of-thumb scaled from common quiver charts; board volume scales similarly with rider weight and skill.

Experienced sailors adjust by feel. Use this as starting guidance when building a quiver or traveling to new spots.

Windsurfing Tips

Always rig for the strongest expected gusts. A well-tuned sail and board pairing boosts control, planing, and safety.

Quiver Strategy

  • Maintain at least two sails and boards to cover local wind ranges.
  • Use larger boards for learning jibes and waterstarts; smaller for high wind.
  • Invest in adjustable outhaul/downhaul systems for on-water tuning.

Frequently Asked Questions

How accurate is the sail size estimate?

It’s a baseline. Adjust for sail brand, mast stiffness, personal power preference, and spot gustiness.

Do wave boards need smaller sails?

Wave sailing often uses smaller sails for maneuverability. Reduce sail size by ~0.5 m² if riding technical waves.

Can I use this for foiling?

Foiling requires much smaller sails and larger boards with foil-specific volume. Use foiling-specific charts.

What if wind drops mid-session?

Choose a sail slightly larger than needed for gusts or keep a backup sail rigged for quick swaps.

Do wetsuits impact board volume?

Wetsuits add buoyancy; minimal impact on board choice, but colder water may require thicker suits affecting agility.
