Line Starts and Shore Starts

When the fleet does not freely cross the start line in the pre-start area but is held on lines or sets sail directly from shore, different rules, different risks and different organisational requirements apply. Line starts (also called held starts) and shore starts (beach starts) are established procedures for dinghies, catamarans, windsurfers and kiteboarders – especially with large fleets, confined venues or events with a high spectator share. For the race committee (RC) this means: precise SI wording, clear line or beach organisation and consistent safety planning. For sailors: anyone who does not know the procedure not only loses seconds but risks protests, penalties or dangerous situations immediately after the start signal.

What distinguishes line starts and shore starts

Both procedures have in common that boats do not manoeuvre classically in the pre-start area in front of the start line. The difference lies in the holding position and the release moment.

Line start – boats fixed on the line

In a line start the RC or helpers on shore or on boats hold starters on lines or warps along a start line. The boats typically lie head to wind or slightly off the wind and wait for the start signal. At the signal all lines are released simultaneously – the fleet sets sail without having crossed the line beforehand.

Shore start – boats start from the beach

In a shore start the boats are ready on the beach, pier or ramp. At the start signal sailors run or push their boats into the water and set sail. There is no classic start line in the Olympic sense; instead the SI defines a start zone or an imaginary line parallel to the shore.

When which procedure makes sense

Organisers choose line or shore starts for pragmatic reasons – not because they are easier, but because they solve specific problems.

1. Confined venue: Without sufficient room for pre-start manoeuvring in front of the line, a line start is the safer alternative to an Olympic mass start.
2. Large fleets: With 100 or more Optimists, ILCA or 420s a line start prevents chaotic crowding in the last minute before the start.
3. Spectator proximity: Stadium and short-course formats benefit from line starts because the entire fleet sets sail synchronously and is clearly visible.
4. Beach venues: Catamarans, Formula Kite and windsurfers start from shore anyway – a shore start is the logical consequence here.
5. Wind conditions: In very light wind or strong onshore a line start prevents boats from crossing the line too early or lying stationary in the pre-start area.

The broader context for start procedures in general is covered in Start Procedures. For Olympic mass starts with a free line see Olympic and Match Race Starts.

Line start – procedure and organisation

A professional line start requires more personnel, clear communication and a practised release sequence. The RC must not improvise – any ambiguity leads to unfair advantages or safety incidents.

Setting up the start line

The start line connects two fixed points, typically the committee boat at the leeward end and a pin-end boat or mark at the windward end. Along this line the boats are positioned in the order specified by the RC – often by sail number, age class or draw.

Important parameters:

• Line length and strength: Lines must not break in gusts and crew movement but must run freely immediately on release
• Spacing between boats: At least one boat length plus safety margin, more for large fleets
• Wind orientation: Boats lie so they can sail away without collision after release
• Helper position: Each line needs a responsible helper with radio or hand signals to the RC

The technical equipment of the RC is described in Committee Boat and Mark Boats.

Signal sequence for line starts

In most cases the RC uses the classic 5-minute sequence – adapted to the SI. The difference from an Olympic start: boats must not cross the line because they are physically held. OCS problems arise only after release when a boat passes the line from the wrong side.

1. Positioning (before warning signal): RC and line team arrange boats along the line. Sailors trim sails, check equipment, stay calm.
2. Warning signal (−5 min): Class flag hoisted, one sound signal. Final position corrections allowed as long as the SI provide for them.
3. Preparatory signal (−4 min): Flag P hoisted, one sound signal. Boats are fixed – no position changes unless the SI allow otherwise.
4. One-minute signal (−1 min): P lowered, one sound signal. Line team takes tension, helpers ready to release.
5. Start signal (0 min): Sound signal – release all lines simultaneously. Boats set sail.
6. After the start: RC watches for OCS, sets recall signals if necessary, documents delayed release of individual lines.

The meaning of the flags is explained in Start Signals and Flags.

Common mistakes in line starts

Shore start – procedure from beach to race

Shore starts are typical for disciplines where boats start from shore anyway: beach catamarans, Formula Kite, windsurf classes and some dinghy events at beach venues. The RC defines in the SI a start zone, start order and the moment from which a boat is considered „started".

Elements of a shore start

1. Start zone: The area between two marked points on shore or between shore and an offshore mark.
2. Start line: Often an imaginary line perpendicular to the shore or parallel to the beach line – described exactly in the SI.
3. Start order: With large fleets boats start in flights (groups) at minute intervals.
4. Launch zone: Area where boats may be launched – separate from the start zone to avoid collisions.

Signals and countdown

Shore starts often use a shortened sequence – e.g. 3 or 5 minutes – depending on SI and discipline. At kite and windsurf events the RC may additionally use visual signals (traffic light, flags on shore) because sound signals are harder to hear on the beach.

Typical procedure:

1. Boats ready in the start zone, sails still furled or partly set (SI-dependent).
2. Warning signal: sailors prepare launch.
3. Preparatory signal: take position in the start zone, no premature entry into the water.
4. Start signal: boats may enter the water – anyone who starts before is OCS or disqualified (SI-dependent).
5. First boat to cross the start line correctly serves as reference for subsequent starters.

Safety in line and shore starts

Safety takes priority over fairness and pace. Both procedures carry specific risks that the RC must address in the SI and safety concept.

Line start – safety aspects

• Line breakage: Keep spare lines ready, define wind limit
• Collision after release: Sufficient spacing, clear give-way rules in the briefing
• Crew in the water: Life jackets mandatory, fix helmsman position before release
• Helper safety: Line team with buoyancy aids, clear escape routes in gusts

Shore start – safety aspects

• Surf and bottom: Start only with sufficient water depth and controllable surf
• Launch chaos: Separate zones for preparation and start
• Kite and windsurf lines: Minimum spacing between starters, observe wind window
• Spectator management: Barriers on the beach so spectators do not run into the start zone

Tactics for sailors

Line start – tactical tips

1. Position on the line: The windward end is often advantageous – clarify order with the RC early.
2. Sail preparation: Trim main and headsail optimally before being fixed – no time for major adjustments after release.
3. Release moment: React to the sound signal, not to neighbours' visual release – otherwise risk of protest for early start.
4. First manoeuvres: Plan course to the first mark immediately after the start – on windward-leeward courses every second counts.

Shore start – tactical tips

1. Launch technique: Get into the water faster than the competition – without violating the SI.
2. Wind window: For kite and windsurf choose the right moment to start when a gust is approaching.
3. Beach choice: Harder ground makes for faster launch; soft sand slows you down.
4. First mark: Set course early – shore starters are often slower to get up to speed than line starters.

Recall and protests

Line and shore starts are subject to the same recall rules as Olympic starts – unless the SI specify otherwise. For OCS after release or premature launch individual recall (flag X) or general recall apply depending on the SI.

Details on recall signals can be found in Individual Recall and General Recall.

Typical grounds for protest:

• Uneven release of lines (early start advantage)
• Boat blocks neighbour after release (rule 11)
• Premature launch in shore start
• Wrong position in start order

Checklist for the race committee

• Procedure (line or shore) clearly described in SI
• Start line or start zone marked and GPS-coordinated
• Line team or beach team briefed and practised
• Radio link between RC, pin end and helpers tested
• Signal sequence and countdown time defined
• OCS and recall rules explained in briefing
• Safety concept (wind limit, rescue forces) agreed
• Practice run with few boats completed
• Documentation prepared for protest committee

Planning in the sailing instructions

Every detail must be in the sailing instructions (SI) – not verbally, not „as last year". At minimum these points are mandatory:

1. Designation of start procedure (line start or shore start)
2. Exact definition of start line or start zone (coordinates, markings)
3. Signal sequence and countdown duration
4. Rules for OCS, early start and delayed release
5. Start order or flight division
6. Wind and wave limits for shore starts
7. Recall system (I-flag, U-flag, general recall)
