Reefing and heavy weather trainer
Reefing is a judgment call, not a bravery test. Practice the beginner loop: notice gusts, heel, weather helm, crew comfort, and forecast trend; depower early; reef while the boat is still under control.
Saved reefing mastery
Scores, weak calls, saved plans, and sequence practice are stored in this browser as asa101.reefingHeavy.v1. Use weak review after a run to repeat missed heavy-weather calls.
Heavy-weather tactics simulator
Choose skipper actions as wind, sea room, crew condition, and forecast risk change. Misses save into the same weak-call review as the reefing cards.
Reefing and heave-to checkoff
Prove the full sail-reduction loop: trigger, crew brief, sea room, sequence, control check, and exit plan. Weak checkoffs can become drill-library repairs.

Sequence builder
Build the sequence in order. The exact sequence is boat-specific, but this drills a conservative slab-reef and heave-to mental model for ASA 101-style practice.
Beginner reefing rules
Reef early
If you are thinking about reefing, that is a signal to prepare. It is easier to reef before the boat is pressed, the crew is tired, or sea room disappears.
Depower first
Ease the main, traveler, or vang; feather briefly; flatten if your boat has the controls. If the condition persists, shorten sail instead of fighting the helm.
Weather is a gate
Thunderstorms, cold water, lee shores, and small craft advisories are go/no-go issues for a beginner day sail. Reefing is not a lightning plan.
Heave-to to pause
Heaving-to can create a stable pause for instruction, rest, or troubleshooting. Practice only with instructor approval and sea room.
