VMG Calculator (tidal, naive)

VMG Calculator (tidal, naive): boat reference frame; BTW held fixed (teaching simplification)

TWA: true wind angle 60°

TWS: true wind speed 15 kts

SOW: speed over water 5 kts

BTW: bearing to waypoint 60°

Tide dir: relative to boat 0°

Tide speed 0 kts

VMG: velocity made good 2.5 kts

AWA: apparent wind angle 46.1°

AWS: apparent wind speed 18.0 kts

SOG: speed over ground 5.0 kts

SOW: boat speed

VMG: toward waypoint

TWA: true wind

AWA: apparent wind

BTW: bearing to waypoint

Tide: current relative to boat
