The Zone Snapshot — Mark-Room Is Decided Three Lengths Out (Rule 18.2)

Your rights at the mark are a photo taken at the zone — the mark itself is too late.

No Mark-Room on Opposite Tacks at the Windward Mark (Rules 18.1 & 10)

Rule 18 is switched off on opposite tacks upwind — it's plain port-starboard.

The Tack You Were Forced Into Doesn't Count Towards Your Penalty (Rule 44.2)

Count the turns only after you're well clear — the forced tack is not yours to claim.

Clearly Overlapped at the Zone — The Outside Boat Gives Room (Rule 18.2)

Overlapped at the zone — starboard tack doesn't buy the outside boat a way out.

You Touched the Start Pin — Here's the Turn That Actually Clears It (Rules 31 & 44.2)

Hitting the pin isn't fatal — but only a turn with a tack and a gybe clears it.

Does a Penalty Turn Need Both a Tack and a Gybe? (Rule 44.2)

Gybe but no tack? The penalty didn't happen — the foul is still live.

Same Tack, No Overlap — Clear Astern Keeps Clear (Rule 12)

No overlap, same tack — the boat behind keeps clear, full stop.

Opposite Tacks Converging — The Tack Decides, Not the Gap (Rule 10)

Port keeps clear of starboard — the tack decides the crossing, not the gap.

Mark-Room Is Owed From the Zone — Even If the Inside Boat Gets Her Overlap Later

Mark-room owed at the zone stays owed — a later overlap doesn't cancel it.

You Gybed But Never Tacked — The Penalty Turn Doesn't Count (Rule 44.2)

A circle isn't a penalty — the rule counts one tack and one gybe.

Opposite Tacks on the Start Line — Who Gives Way? (Rule 10)

The start line is not a special zone — Rule 10 applies right through the gun.

Returning to the Pre-Start Side — You Keep Clear of Everyone (Rule 21.1)

Turn back to restart and Rule 21 strips your right of way — starboard included.

Hit a Boat and the Mark in One Incident — One Penalty or Two? (Rule 44.1)

One incident, one Two-Turns Penalty — even when you hit the boat and the mark.

Starboard Had to Bear Away — That Alone Proves Port Broke Rule 10

The crash bear-away is the evidence — no contact needed to lose the protest.

You Hit a Mark AND Another Boat — Does One Penalty Cover Both?

Hitting a boat and a mark in one sequence can mean two separate penalties.

You Have Right of Way at the Mark — But You Still Owe Room

Right of way under Rule 11 doesn't cancel a separate mark-room duty under 18.2.

Hit a Mark? The Correct Rule 44.2 Penalty Turn

Touching a mark clears with one tack AND one gybe, taken promptly.

Catching Up Downwind Doesn't Earn You Right of Way (Rule 12)

Closing the gap downwind buys you no rights until an overlap actually forms.

Overlapped Downwind — Rule 11 Still Applies

Downwind isn't a free-for-all — Rule 11 still decides who keeps clear.

It Looks Like a Crossing — But Check the Sails First

Same-side sails mean same tack — Rule 11 governs, not Rule 10.

Same Tack and Overlapped — The Basics of Rule 11

Same tack, overlapped — windward keeps clear of leeward, no exceptions.

Boats Meeting at an Angle — Same Tack, Not Opposite Tacks

Check the boom, not the heading — it decides Rule 10 versus Rule 11.

Someone's Climbing Your Transom Downwind — Who Gives Way?

Downwind, being ahead means nothing — the boom decides who gives way.

Boat Climbing Your Transom on Opposite Tacks — Gybe to Flip It

Being ahead downwind is worth nothing on the wrong tack — one gybe fixes it.

One-Turn Penalty — Why a Tack Alone Doesn't Clear You

A tack alone isn't a penalty turn — Rule 44.2 needs a tack AND a gybe.

Running Side-by-Side Downwind — How to Find Which Boat Is Leeward

Side by side downwind, leeward is found from the wind, not from below.

Pre-Start Overlap — The Windward Boat's Duty Under Rule 11

Pre-start overlap still runs on Rule 11 — leeward can luff to defend her lane.

Two Boats Running Downwind — How to Tell Who's on Which Tack

Dead downwind, the boom names the tack when the heading can't.

Rule 11 — Same Tack, Overlapped: Leeward Has Right of Way

Same tack, overlapped — windward keeps clear of leeward, every time.

Starboard vs Port — Identifying Your Tack Under Rule 10

Knowing which side the wind hits first is the whole of Rule 10.

Rule 12: Clear Ahead vs Clear Astern — Who Keeps Clear?

Same tack, no overlap — the boat clear astern keeps clear.

Opposite Tacks Closing Upwind — Read the Tack, Not the Gap

The tack decides the crossing, not the gap between the boats.

Overlapped Downwind — Why the Leeward Boat Holds Right of Way

Overlapped downwind, the leeward boat is protected by Rule 11.

Two Boats, Opposite Tacks — Who Gives Way? (Rule 10)

On opposite tacks, port keeps clear of starboard — every time.

Beating Upwind on Opposite Tacks — Who Gives Way? (Rule 10)

Beating upwind on opposite tacks — port keeps clear of starboard.

The Wall of Boats at the Start — Who Owes You the Gap? (Case 117)

The wall of boats before the gun — the gap belongs to nobody until you take it.

The Right-of-Way Boat Aims at the Wall — Who Owes Room?

Rule 19 owes no room until the right-of-way boat picks a side — but Rule 11 never waits.

Who Owes Room at a Wall? Rule 19 at an Obstruction

The right-of-way boat picks the side — and that decides who owes room.

Forced Over Early — and Still Scored OCS (Case 140)

Exoneration clears the breach — it doesn't give back the start.

When Covering Becomes Cheating — Rule 2 (Case 34)

Covering to win is legal; covering only to ruin a rival is Rule 2.

Two Ways to Lose a Finish (Case 128)

Crossing the line isn't always finishing — two different ways to lose it.

Rule 17 — You Can't Force the Leeward Boat Above Proper Course

A leeward overlap from astern locks you to your own proper course.

Right of Way, No Lookout — Still Disqualified (Case 107)

Right of way is not a substitute for keeping a lookout.

Don't Force a Boat Into the Mark (Case 114)

Luffing a boat into a mark is your breach, not hers.

Rule 16 — Right of Way Is Not a Licence to Chase

Chase a boat with your course changes and Rule 16 throws you out.

Hold Your Course and Still Get Disqualified (Case 125)

At an obstruction the outside boat owes room for the whole group.

"Barging" Isn't Even a Rule (Case 146)

Compelled in: protected. Chose to barge: not.

Starboard Luffed Into You, Then Protested — and Lost (Case 147)

You can't luff a boat into a breach and then protest it.

The Room-to-Tack Hail Must Relay Down the Line (Case 113)

The room-to-tack hail must ripple all the way up the line — or nobody gets out.

Who Chooses Which Side of the Obstruction? (Case 124)

The right to choose the side belongs to whoever has right of way right now.

Inside at the Mark Isn't Room for the Whole Corner (Case 118)

Mark-room is room to round, not room for the whole corner.

Short-Handed? You Still Don't Get Extra Room (Case 103)

A small crew doesn't earn you extra room.

Right of Way Won't Save You From Rule 14 (Case 123)

Both boats disqualified — right of way doesn't cancel Rule 14.

She Said "You Tack" — Then Won the Protest (Case 101)

"You tack" gives you room — not right of way.

One Radio Call Got Her Disqualified (Case 100)

Ask for tactics on the radio and you're out.

Must You Dodge an Out-of-Control Boat? (Case 99)

Right of way doesn't mean you must risk your own boat.

One word — sheet vs guy — makes it legal.

The Black Flag Mistake That Ends Your Series (Case 96)

Race the restart and your black flag becomes permanent.

The Windward-Mark Mistake That Disqualifies You (Case 95)

Tack inside the zone and every line afterwards loses.

He Touched Your Boat on Purpose — and You Got DSQ'd? (Case 73)

Fake a foul by touching a boat — that's the foul.

New Right of Way? Give Room First (Case 93)

New right of way? Give room before you luff.

Case 105 — Luffed Downwind: Why Holding Your Course Gets You DSQ'd

Running on port, luffed by starboard — hold your course and you're out.

Keep Clear Means Their Gear Too (Case 91)

Clear astern means keeping clear of her gear too — even a kite that's flogging.

The String Rule: Did These Boats Start? (Case 90)

Pull your track tight like a string — it must leave every mark on the right side.

Avoiding the Crash Isn't the Same as Keeping Clear (Case 88)

No contact isn't proof you kept clear — if she had to swerve, you broke Rule 10.

Even the Right-of-Way Boat Must Avoid Contact (Case 87)

Right of way doesn't excuse you from avoiding a crash you still can't prevent.

When You Can Cross the Finish Line Either Way (Case 82)

A finish line you can't read lets you cross either way — first crossing counts.

Your Mark-Room Doesn't Survive Your Own Tack (Case 81)

Mark-room gives you room to round — it doesn't survive your own tack.

The Late Recall and Your Right to Redress (Case 79)

A recall flag forty seconds late earns you redress, not last place.

Is Covering a Rival Cheating? (Case 78)

Covering to win is fair. Covering out of spite breaks Rule 2.

Two Contacts at the Mark, One Penalty (Case 77)

Two contacts at the mark — only the mark-touch is penalised.

Mark-Room Is a Floor, Not a Cap on Right of Way (Case 75)

Giving mark-room doesn't take away the other boat's right of way.

When the Other Boat Isn't Racing, the Racing Rules Switch Off (Case 67)

Meet a boat that isn't racing? The racing rules switch off.

Already Disqualified? Covering a Rival Can Get You Banned (Case 65)

Already out? Sitting on a rival anyway can get you banned.

You May Take Inside Room You Weren't Owed — At Your Own Risk (Case 63)

That gap on the inside? You're allowed to take it — at your own risk.

You Owe Mark-Room to the Boat That Overlaps Inside You (Case 59)

Out wide to be fair? You still owe the boat that overlaps inside you.

You Finish At The Line — Limit Marks Have No Required Side (Case 58)

You finish at the line — a limit mark past it has no required side.

About to Hit the Rocks — Room to Tack at an Obstruction (Case 54)

Trapped near the shore — how to hail for room to tack at an obstruction.

"Leeward Boat!" — Do You Have to Move Instantly? (Case 53)

The leeward-boat hail on the line — Rule 15 gives you time to respond.

Boxed Out At The Start — Is That Legal? (Case 52)

Boxed out at the start — why it's legal, and how right of way really works.

Forced to Bear Away at the Start? You're Exonerated (Case 51)

The start-line concertina — Rule 43 exoneration when you're forced down.

No Contact Is Still a Foul — Rule 10 (Case 50)

No contact isn't the test — if starboard has to avoid you, port has fouled.

The Boat That Touched No One Got Disqualified (Rule 19.2(b))

Right-of-way boat as an obstruction — the outside boat owes inside room.

The Fake "Starboard!" Hail Breaks Two Rules (Case 47)

The fake 'Starboard!' bluff breaks two rules — and Rule 2 means DSQ.

She Came From Behind, Then Luffed You Up — Can She Do That? (Case 46)

Leeward boat can luff up TO her proper course — even when she came from behind.

Pinned Between Starboard and the Bank — Can I Call for Room? (Case 43)

Port keeps clear of starboard — even pinned against the bank.

Overtaking a Slower Boat to Leeward — When Does Right of Way Flip? (Case 41)

Rule 12 → 19.2(b) → 11 → 15, in the space of one overtake.

She Answered "You Tack" Instead of Tacking — Is That Legal? (Case 35)

"Room" is what you need to manoeuvre — not a cushion.

She Hailed for Room Too Early — Can I Ignore It? (Case 33)

A bad hail doesn't free you from responding.

OCS But No Horn — Do You Have to Go Back? (Case 31)

No horn doesn't save you if you know you were over.

Clear Astern on Starboard — How Is the Foul Mine? (Case 30)

Blanket the boat ahead and cause contact — that's on you.

Fouled at the Start, Won the Protest — So Why Scored DNS? (Case 28)

Win the protest, skip a mark, still go home last.

You Won the Protest and Still Scored DNS — Here's Why

Winning your protest doesn't excuse a missed mark — you still have to sail the course.

She Dove Into the Gap Below You — Did You Owe Her Room? (Case 29)

A boat under way isn't a "continuing obstruction" — could you have given room from the start?

You Tacked onto Starboard at the Mark and Got Hit — Why Are You Out? (Case 27)

Tack too close and the crash is yours — even when she hits you.

We Collided at a Mark With Damage — How Can BOTH Be Disqualified? (Case 26)

Right of way is not a right to collide — keep a lookout.

I Rounded the Leeward Mark Cleanly — How Am I Disqualified?

Mark-room ends when you leave the mark astern.

How Much Mark-Room Am I Actually Owed? (Rule 18)

No fixed amount — what you need in the conditions.

You Fouled a Boat and Did Your Turns — But There Was Damage (Rule 44)

Take a turn for a foul; retire if you caused damage.

You Tacked in Front of a Starboard Boat — Whose Fault? (Rule 13)

Rule 13 ends at close-hauled — then you owe room.

You Overtook to Leeward — Now Give Room (Rule 12 → 11 → 15)

Overtaking to leeward — take what's yours, but not instantly.

Starboard Squeezes Between Two Port Boats Downwind — Who's Wrong?

Continuing obstruction is not a get-out clause.

The Boat Behind Won't Tack at the Mark — Can She Do That?

A boat behind owes you mark-room — not a tack.

Can the Leeward Boat Head Up On Me? (Case 14)

The leeward boat doesn't owe you a straight line to the mark.

Pre-Start Luff — The Leeward Boat Can Go Head to Wind (Case 13)

The pre-start luff trap — Rule 17 doesn't apply before the gun.

She Came In From a Different Angle — Can I Shut the Door? (Case 12)

It looks like barging — it isn't. Inside the zone you owe mark-room.

Proper course, after gaining an overlap from clear astern.

Room to Tack at an Obstruction (Rule 20, Case 10)

Port tack trapped on the layline. What you're allowed to call.

Mark room: how the inside overlap formed and what you owed.

When the Starboard Boat Still Gets Penalised

When the right-of-way boat still gets penalised.

Rule 11 — Windward Boat Keeps Clear

Same tack, overlapped — who has to move?

Rule 10 — Port and Starboard: Who Has Right of Way?

The most common rules mistake at club level.
