Sailing maneuvers, made practical
ASA 101 is not just naming things. You need to steer, trim, control speed in tight water, talk to crew, recover mistakes, back and fill around obstacles, and bring the boat home under control.
Saved maneuver decision drill
Practice the skipper call before reading the guide. Scores and weak moves are saved in this browser as asa101.maneuvers.v1.
Maneuver sequence trainer
Click the exact action order for high-consequence maneuvers: clean tack, controlled jibe, quick-stop crew overboard, reefing, and return/secure. Sequence runs are saved in asa101.maneuvers.v1 and weak sequences feed the weak-area coach.
Choose a maneuver sequence.
Jibe safety lab
Practice the judgment around controlled jibes, accidental-jibe risk, and chicken-jibe choices. Runs save under asa101.maneuvers.v1.jibeSafetyRuns; weak topics can be queued as drill-library repairs and exported to the logbook.
Choose a jibe safety scenario.
Close-quarters control lab
Practice the action order for the on-water skills schools evaluate: slowing under sail, recovering from irons, backing the jib around an obstacle, short-tacking inside a box, and heaving-to. Control runs and weak control mistakes are saved in asa101.maneuvers.v1.
Choose a control scenario.
Closed-course under-sail checkoff
Combine the close-quarters pieces into one instructor-style station: brief the route, sail a triangle or box, control speed, tack, jibe, avoid traffic, recover mistakes, and stop or pause at the target. Saved checkoffs feed readiness, weak-area repair, drill library, and logbook evidence.

The two steering words
Heading up
Turn the bow toward the wind. As you head up, sails usually need to come in. Head up too far and the sails luff; farther still and you are in irons.
Bearing away
Turn the bow away from the wind. As you bear away, ease the sails. Bear away past a broad reach toward a run and watch the boom closely.
Tacking: bow through the wind
A tack moves from one close-hauled course to the other by turning the bow through the no-sail zone. It is controlled and common. The risk is stopping in irons if you turn too slowly, start without speed, or let the crew miss the jib.
- Skipper checks traffic and says, "Ready to tack?" or "Ready about?"
- Crew answers, "Ready."
- Skipper turns and says, "Hard alee" or "Helm's alee."
- Old jib sheet is released as the bow crosses the wind; new sheet is trimmed as the jib fills on the new side.
- Settle on the new close-hauled course and trim both sails.
Jibing: stern through the wind
A jibe changes tack downwind. It is useful, but the boom crosses with force if uncontrolled. ASA 101 crews learn to keep heads low, center or control the mainsheet, and move deliberately.
- Skipper checks traffic and says, "Ready to jibe?"
- Crew answers, "Ready."
- Trim the mainsheet enough to control the boom.
- Skipper bears away through dead downwind and calls, "Jibe-ho."
- Ease the main on the new side, trim the jib if used, and stabilize the new course.
Getting out of irons
In irons means the bow is pointed into the wind, sails are flapping, and the rudder has little or no water flow. Recover by making the boat rotate off the wind:
- Back the jib to one side so it pushes the bow away.
- Push the boom out to help the bow fall off.
- If you have sternway, reverse the tiller logic and let the rudder swing the stern.
- If auxiliary power is available and your instructor allows it, use a short controlled burst to regain steerage.
Crew overboard
ASA schools vary in the exact recovery pattern they teach, but the priorities do not change:
- Shout "crew overboard" immediately.
- Throw flotation right away, even if the person is close.
- Assign one person to point continuously. Losing sight is the emergency inside the emergency.
- Return under control. A close-reach final approach lets you luff to slow or trim to power up.
- Stop beside the person, not on top of them. Recover from the leeward side if conditions and boat layout allow.
Docking and mooring
Docking is slow-speed seamanship. ASA 101 often introduces it even when auxiliary power is optional.
- Rig fenders and dock lines before entering the tight space.
- Know wind and current. The boat will drift sideways when you lose speed.
- Approach no faster than you are willing to hit the dock.
- Step off only when safe. Do not leap with a dock line.
- Use bow, stern, and spring lines. Spring lines stop fore-and-aft movement.
Anchoring basics
ASA 101 does not turn you into a cruiser, but you should know the vocabulary and the safe sequence.
- Pick a spot with room to swing, suitable depth, and good bottom.
- Approach slowly into wind or current.
- Lower, do not throw, the anchor.
- Pay out rode as the boat drifts back. More scope gives better holding.
- Set the anchor gently, then confirm you are not dragging using transits or GPS.
Reefing and depowering
Reef before the boat feels out of control. Too much sail creates excess heel, weather helm, poor steering, and tired crew. Depower in layers: ease sheets, flatten with outhaul/vang/traveler if fitted, then reef or change sail.
