## Mainsail aerodynamic coefficients (calculation)

A mainsail is a sail with the luff attached to the mainmast. The mainmast is the only mast in a una rig, sloop rig, or cutter rig, the fore mast in a ketch rig or yawl rig, or the aft mast in a schooner rig.

## Headsails “Set Flying” aerodynamic coefficients (calculation)

A headsail is a sail set forward of the mast. Headsails may be set on the forestay or set flying, i.e., with no sail edge attached to the forestay. With this template, you can calculate the aerodynamic coefficients of flying headsails as determined by the Offshore Racing Congress (ORC).

## Spinnakers aerodynamic coefficients (calculation)

Spinnakers are sails set forward of the mast where the measurement between the half luff point and the half leech point (SHW) is equal or greater than 75% of the foot length (SFL). There are two types of spinnakers: symmetric and asymmetric.
