Sail Area=Mainsail Hoist×Mainsail Foot2

Variables:

Variable Description
Mainsail Hoist Height of the mainsail (ft)
Mainsail Foot Base of the mainsail (ft)
Sail Area Total area of the sail (ft²)

How To Calculate Sail Area ?

Example 1:

  • Mainsail Hoist: 30 feet
  • Mainsail Foot: 15 feet

1. Use the formula:

Sail Area=30×152

2. Calculate:

Sail Area=4502=225 ft²

Example 2:

  • Mainsail Hoist: 20 feet
  • Mainsail Foot: 12 feet

1. Use the formula:

Sail Area=20×122

2. Calculate:

Sail Area=2402=120 ft²
