TACK LAB / SAILING PRACTICE
Coming to iPhone
From your first sail trim to finding your way home. Practice the small decisions that make sailing feel more familiar, aboard a small keelboat.
Short lessons. Complete voyages. Your own pace.

From wind to water
01 / LEARN BY SAILING
You don’t have to learn every term at once. Start with where the wind comes from, then explore how your heading, sail trim and speed work together.
Recognize the wind direction. Try sheeting in and easing out. Your first two lessons are free, with room to revisit the basics as often as you like.
Wind awareness · Sail trim
Practice tacks, gybes and wind shifts before taking on an independent voyage. Each lesson adds one more decision for you to make.
Tacks & gybes · Wind shifts · Independent sailing
Connect leaving the berth, sailing offshore and a controlled return across nine passages in three harbor worlds.
Departure · Passage · Return & berth
02 / ROOM TO TRY AGAIN
Rewind up to 12 seconds and try a different decision in the same voyage. Or open your local logbook, replay a passage and find a moment worth practicing again.

Tack Lab is simplified virtual sailing practice, not a nautical chart or sailing qualification. Learn on the water with a qualified instructor before sailing for real.
