**Mass in Minimum Operating Condition (mmoc)**

**mmoc** is defined by ISO 12217-2. It is the anticipated minimum weight that the boat will be when in use.

It is composed of Boat Weight plus various additions as follows:

**Weight of Sails**: 0.8 * (LH ^ 2) where LH is Hull Length

**Weight of Stores**: = **Weight of Sails**

**Weight of Crew**:

If LH <= 8 Then **Weight of Crew** = 75

If LH > 8 and LH <= 16 Then **Weight of Crew** = 150

If LH > 16 Then **Weight of Crew** = 225

**Weight of Safety Equipment**: (LH - 2.5) ^ 2

**Weight of Liferaft**: 14 + 2.5 * ((LH - (LH ^ 0.5)) / 0.0106) / 80

**mmoc: Boat Weight + Weight of Sails + Weight of Stores + Weight of Crew + Weight of Safety Equipment + Weight of Liferaft**
