(V_A) is only a few degrees from the direction of travel on most points of sail and the sail is close-hauled in each. V_A is generated by the combination of iceboat velocity (V_B) and true wind velocity (V_T).

Attainable speeds

Different classes of iceboat can achieve speeds, as follow.

* International DN: .
* Skeeter: .
* Classic iceboats: While claimed speeds for such craft have been as high as in the early 20th century, other
