Note · 提示

Items 15–17 (vang, cunningham, outhaul) are the three "sail-shape controls." You'll meet them again in Section 04 — for now just know where they live.

第 15–17 项(压帆器、帆领下拉、帆脚外拉)是三大"帆型控制索"。第 04 节会再次用到,这里先记住它们的位置即可。

02

Rigging, Step by Step / 组装与装配步骤

From a bag of parts on the beach to a boat ready to launch. Always rig head-to-wind (bow pointing into the wind) so the sail flaps freely instead of powering up while you work. 从沙滩上一堆零件,到一艘可以下水的船。组装时务必让船头正对来风,这样帆会自由抖动而不会突然吃风。

UPPER 上节 LOWER 下节 push
STEP 01

Assemble the mast接桅杆

Push the upper mast section firmly into the lower section until the spigot seats fully.

把上节桅杆用力插入下节,直到接头完全到位、不再松动。

SAIL 帆 thin end first 细头朝里 leech 后缘插袋
STEP 02

Batten, then sleeve先插帆骨,再套帆

First slide the battens into their leech pockets (thin end in, snug not forced). Then sleeve the sail's luff over the mast, head first, all the way up.

先把帆骨逐根插入帆后缘的插袋(细头朝里,插紧但别硬顶)。再把帆前缘的套筒从桅杆顶端套下,一路推到帆顶到顶。

mast step 桅座
STEP 03

Step the mast立桅

Lift the mast vertical and drop its base into the mast step in the foredeck. It should spin freely.

把桅杆竖起,将底端插入前甲板的桅座。装好后桅杆应能自由转动。

gooseneck 接头 clew 帆脚
STEP 04

Attach the boom装帆杆

Clip the boom to the gooseneck on the mast, then hook the sail's clew to the boom end.

把帆杆扣到桅杆的接头(gooseneck)上,再把帆的后下角(帆脚)挂到帆杆末端。

vang 压帆器 cunningham 下拉 outhaul 外拉
STEP 05

Rig the control lines接帆型控制索

Connect the three sail-shape lines: outhaul, cunningham and vang. These are the trickiest part — full breakdown below.

连接三条帆型控制索:帆脚外拉、帆领下拉、压帆器。这是最难的环节——详解见下方「帆型三索」。

boom 帆杆 tied off 系死 traveler 缭桥 ratchet 棘轮 to hand 到手中
STEP 06

Reeve the mainsheet穿主缭

Lead the sheet through the block system so a light pull on your end trims the whole sail. How the purchase works is explained below.

把主缭穿过整套滑轮,这样你手上轻轻一拉就能收紧整面帆。滑轮组的工作原理见下方详解。

pintles 舵针 tiller 舵柄
STEP 07

Fit the rudder & tiller装舵

Hang the rudder on the transom pintles and lock it down; slide the tiller forward under the traveler. Tie off the rudder hold-down and finish loose line-ends with a stopper knot (knots below).

把舵挂到船尾的舵针上并锁住;舵柄从缭桥下方向前穿入。系好舵的下压绳,并在松散的绳头打一个止索结防脱出(绳结见下方)。

daggerboard 稳向板
STEP 08

Daggerboard & launch插稳向板、下水

Drop the daggerboard into its slot (leave it half-up near shore), launch, then push it fully down in deep water.

把稳向板放入插槽(近岸先插一半),下水后在深水处再完全插到底。

The three control lines, explained 帆型三索详解 · 装配中最容易搞混的部分

Three ropes, three edges of the sail. Each one tensions a different edge to change the sail's shape. Pull them all on to flatten and de-power in strong wind; ease them all off for a deep, powerful sail in light wind. 三条绳,对应帆的三条边。每条张紧一条边来改变帆型。大风时三条全收紧=帆变平、减力;小风时三条全放松=帆变鼓、加力。

FIG 2.AEach line tensions one edge of the sail · 每条索张紧帆的一条边
Line · 控制索
改变什么
What it does & when to use · 作用与使用时机
Outhaul
帆脚外拉索
foot 下缘
Pulls the clew out along the boom, tensioning the foot and flattening the lower third of the sail. Pull on for flat water / stronger wind; ease off in light wind or waves for more power.把帆脚沿帆杆向外拉,张紧下缘、使帆下三分之一变平。平水或大风时收紧;小风或有浪时放松以加力。
Cunningham
帆领下拉索
luff 前缘
Pulls the luff (front edge) down, smoothing wrinkles and dragging the sail's deepest point forward. Pull on as the wind builds to de-power and keep the helm light; ease off in light air.下拉帆前缘,抚平褶皱并把帆最鼓的点前移。风变大时收紧来减力、让舵变轻;小风时放松
Vang / Kicker
压帆器
leech 后缘
Pulls the boom down, tensioning the leech and controlling twist (how far the top of the sail falls open). The most powerful of the three — keep it on downwind and in gusts; ease when sitting in light air. It also stops the boom skying when you let the sheet out.下压帆杆,张紧后缘、控制帆顶的扭转(帆上部张开多少)。三者中最有力——顺风和阵风中保持收紧;小风静坐时放松。它还能防止你放缭时帆杆翘起。
Remember · 口诀

Three lines, three edges — outhaul = foot, cunningham = luff, vang = leech. More wind → pull all three on (flat sail). Less wind → ease all three off (full sail).

三索对三边:外拉=下缘下拉=前缘压帆器=后缘。风大全收紧(帆平);风小全放松(帆鼓)。

How each line is actually tied on 三索如何用绳连接 · 接到哪里、怎么走线

Each line attaches at the sail/spar corner it controls, runs through one or more blocks to multiply your pull, and finishes at a cleat you can release. Below: where each one starts, where it leads, and which way you haul it. 每条索都接在它所控制的帆角/桅杆部位,穿过一个或多个滑轮来放大拉力,最后落到一个可随时松开的角索上。下面分别给出:从哪里起、走到哪里、往哪个方向拉。

clew 帆脚 block 滑轮 cleat 角索 pull out → 向外拉=张紧下缘
OUTHAUL · 帆脚外拉

Clew → boom-end block → cleat帆脚 → 帆杆端滑轮 → 角索

Tie the line to the clew, lead it around a block at the aft end of the boom, then forward along the boom to a cleat. Pulling the tail draws the clew out and flattens the foot.

把绳系在帆脚,绕过帆杆末端的滑轮,再沿帆杆向前引到角索。拉绳尾就把帆脚向外拉、压平下缘。

luff cringle 帆领孔 block 滑轮 cleat 角索 pull down ↓ 下拉=张紧前缘
CUNNINGHAM · 帆领下拉

Luff cringle → gooseneck block → cleat帆领孔 → 帆杆接头滑轮 → 角索

Thread the line through the cringle (eyelet) low on the front edge, down through a block at the gooseneck, then to a cleat. Pulling down stretches the luff and flattens the sail.

把绳穿过帆前缘下部的帆领孔,向下穿过帆杆接头处的滑轮,再到角索。下拉就拉伸前缘、使帆变平。

mast base 桅座 on the boom 帆杆上 block-and-tackle 多倍省力滑轮组
VANG · 压帆器

Mast base ↔ boom, many parts桅座 ↔ 帆杆,多段绳省力

A block-and-tackle runs between a fitting at the mast base and a fitting under the boom. Many rope falls multiply your pull, so a light hand hauls the boom hard down — controlling leech tension and twist.

在桅座接点与帆杆下方接点之间装一组滑轮组。多段绳放大了拉力,所以轻轻一拉就能把帆杆狠狠下压——控制后缘张力与扭转。

How the mainsheet works 主缭工作原理 · 你的"油门"

The mainsheet is the rope in your hand that pulls the sail in and out. It runs through a set of blocks (pulleys) so a light hand-pull controls the big load on the sail. 主缭是你手中收放帆的那根绳。它穿过一组滑轮,因此手上轻轻一拉,就能控制帆上巨大的受力。

boom 帆杆 tied off 系死 traveler 缭桥 ratchet 棘轮滑轮 your hand 手中(油门)
FIG 2.BOne continuous rope, several blocks = a purchase · 一根绳穿过多个滑轮=省力的滑轮组

Pull = power, ease = spill拉=加力,放=泄力

Pull it in and the boom comes toward the centerline — the sail fills, powers up and points higher. Let it out and the sail opens and spills wind — less power. It is your throttle.

往里收,帆杆靠近中线——帆吃满风、动力增大、能更贴风行驶。往外放,帆张开漏风——动力减小。它就是油门。

The blocks form a purchase (pulley advantage): the load is shared across several rope falls, so you pull a longer length but with much less force — light enough to hold a powered-up sail by hand. The ratchet block grips under load so your hand doesn't tire.

这些滑轮组成省力滑轮组:受力被多段绳分担,你拉的绳更长、但用力小得多——小到能徒手拉住吃满风的帆。棘轮滑轮在受力时会"咬住",让手不易累。

Never cleat the mainsheet in a dinghy. Hold it in your hand so you can dump it instantly in a gust — releasing the sheet is your fastest way to stop a capsize.

小艇上绝不要把主缭固定(上夹)。始终握在手里,阵风一来能立刻松手放掉——松缭是阻止翻船最快的办法。

Essential knots 必备绳结 · 图示捆绑方法

Six knots cover almost everything on a small boat. In each illustration below one rope is shown in orange, and the second rope — or the post / rail you tie onto — in green. 小船上常用的就这六个结。下图中主绳为橙色,第二条绳(或你系上的桩、栏杆)为绿色。图示来自 Wikimedia Commons(公有领域)。

Figure-eight stopper knot
FIGURE-EIGHT · 八字结

Stopper at a rope's end止索结 · 防止脱出

The non-jamming stopper. Put one on the end of the mainsheet and every control line so it can't run out through its block.不会卡死的绳头结。在主缭与每条控制索的绳头各打一个,防止绳子从滑轮中脱出。

Bowline, a fixed loop that will not slip
BOWLINE · 单套结 / 布林结

A loop that never slips or jams不滑、不卡死的固定环

The sailor's most useful knot — a fixed loop for sheets, painters and dock lines that unties easily even after heavy load.水手最常用的结——打出固定大小的环,受力后仍易解开。

Clove hitch around a post
CLOVE HITCH · 卷结

Quick attach to a post or rail快速系到桩或栏杆

Two crossing turns — fast to tie and adjust. Good for fenders and lashing to a rail; back it up with a half hitch if it must hold hard.两道交叉缠绕,打、调都快。适合挂防撞球或绑栏杆;受力大时再加一个半结更保险。

Round turn and two half hitches around a ring
ROUND TURN + 2 HALF HITCHES · 双半结系桩

Tie a boat to a ring or post把船系到环或桩上

The round turn takes the strain while you tie; two half hitches lock it. The go-to for painters, mooring rings and dock posts.先绕一整圈承力,再打两个半结锁住。系缆绳、系泊环、码头桩的首选。

Reef (square) knot joining two rope ends
REEF / SQUARE KNOT · 平结

Join two ends of equal rope连接两条粗细相同的绳

Flat and tidy for bundling a furled sail or tying in a reef. Not for a heavy load or two different-sized ropes — it can capsize and slip.平整服帖,适合捆扎收起的帆或扎缩帆。可用于重载或粗细不同的绳——会松脱。

Sheet bend joining two ropes of different size
SHEET BEND · 接绳结 / 双套结

Join two ropes of different size连接两条粗细不同的绳

The reliable way to bend two lines together — works even when they differ in thickness, where a reef knot would slip. Double the tuck for slippery rope.把两条绳系到一起的可靠方法——即使粗细不同也牢固,而平结在此会松脱。绳子滑时多绕一道更保险。

Safety · 安全

Rig with the bow into the wind and the mainsheet loose. A rigged boat left side-on to a gust can power up and flip on land or knock you down.

组装时船头要正对来风、主缭放松。已装好帆的船若侧对阵风,可能突然吃风,在岸上掀翻或撞到人。

03

Points of Sail / 各点航法(风向与航向)

A boat cannot sail straight into the wind. As you turn away from the wind, the angle of the sail changes — this map of headings is the single most important concept in sailing. 帆船无法正对风行驶。随着航向逐渐偏离风,帆的角度也随之改变——这张"航向地图"是帆船运动中最核心的概念。

NO-GO ZONE 顶风死区 ~45° each side · 两侧各约 45° WIND 风 CLOSE-HAULED 迎风 / 抢风 · ~45° BEAM REACH 横风 · 90° BROAD REACH 顺侧风 · ~135° RUN · 顺风 · 180° PORT TACK 左舷风 STARBOARD TACK 右舷风

In Ironsno-go
顶风死区
0–45°
Pointed into the wind: the sail just flaps and the boat stops. You must bear away to restart.船头正对风:帆只会抖动、没有动力,船会停住。必须转向离风(bear away)才能重新起步。
Close-Hauledbeating
迎风 / 抢风
~45°
Sheeted in tight, boom near the centerline. The closest you can sail to the wind — zig-zag (tack) to make ground upwind.帆收到最紧、帆杆贴近中线。这是能贴风行驶的最小角度——靠左右折线(抢风/换舷)一点点驶向上风。
Beam Reach
横风
90°
Wind straight across the side; boom out about 45°. The fastest, easiest, most comfortable point of sail.风从正侧方吹来,帆放出约 45°。最快、最省力、最好掌控的航法。
Broad Reach
顺侧风
~135°
Wind over the back corner (quarter); boom well out at 60–70°. Very fast and planing-friendly.风从船后侧角吹来,帆放出 60–70°。速度很快,容易"滑行"加速。
Rundead run
顺风
180°
Dead downwind; boom right out near 90°. Feels calm but is unstable — watch for an accidental gybe.正顺风;帆放到接近 90° 的最大角度。看似平静但其实不稳,要小心帆突然甩到另一侧(意外转帆 gybe)。
Key idea · 核心

To go toward the wind you cannot sail straight at it — you tack, zig-zagging at ~45° across the no-go zone. To go away from the wind you gybe, swinging the stern through the wind. As you turn away from the wind, let the sail out; as you turn toward it, pull the sail in.

逆风前进不能直冲,而要抢风换舷(tack),以约 45° 的"之"字形穿过死区。想顺风离开则要转帆换舷(gybe),让船尾扫过风。口诀:向风收帆、离风放帆

04

Sail & Rudder Control / 帆与舵的操纵

You drive a Laser with two hands: the tiller (steering) in your back hand and the mainsheet (power) in your front hand. Two simple rules cover almost everything. 驾驶激光级靠两只手:后手握舵柄(控制方向),前手握主缭(控制动力)。掌握两条简单规则,几乎够用。

heading 原航向 pivot 舵轴 you hold this end 你握这一端 move it to one side 推向一侧 blade swings 舵叶摆向另一侧 bow turns 船头转
FIG 4.1One rigid arm pivoting at the rudder · 舵柄是一根绕舵轴转动的硬杆

Steering — the opposite rule舵——"反向"法则

The tiller is one rigid arm clamped to the top of the rudder; you hold its forward end (usually through a hinged extension, so you can reach it while hiking out). Because the whole arm pivots at the rudder, the end in your hand and the blade under the boat always swing to opposite sides.

舵柄是固定在舵顶的一根硬杆,你握住它伸向船内的那一端(通常再接一根可转动的延伸杆,让你压舷在外侧时也够得着)。整根杆绕舵轴转动,所以你手里那端和船底的舵叶永远摆向相反的两侧

So the boat turns the opposite way to your hand: move the tiller end to port (left) and the bow swings to starboard (right). Move it gently — small nudges, then bring it back to centre. A hard-over rudder just drags like a brake.

于是船的转向和你的手相反:把舵柄末端推向左舷,船头就转向右舷。动作要轻——小幅修正后立刻回中。舵打得太死只会像刹车一样拖慢船速。

An easy memory hook: move the tiller toward the sail/boom = bear away (turn away from the wind); move it away from the boom = head up (turn toward the wind).

一个好记的口诀:把舵柄推向帆/帆杆那一侧=离风转向(bear away);把舵柄拉离帆杆=向风转向(head up)。

Trimming the sail — the flap rule调帆——"抖动"法则

For any course: ease the mainsheet out until the front edge of the sail just begins to flap (luff), then pull in just until the flapping stops. That is perfect trim. Re-check every time you change course or the wind shifts.

无论哪种航向,方法都一样:放出主缭,直到帆的前缘刚开始抖动(luff),再收回到刚好不抖为止——这就是最佳帆型。每次改变航向或风向变化时,都重新调一次。

Telltales tell you faster: both yarns streaming straight back = perfect. Windward (inside) yarn lifting = ease out or bear away. Leeward (outside) yarn fluttering = pull in or head up.

风向毛线更灵敏:两侧毛线都顺直后飘=正确;迎风侧(内侧)毛线上飘=放帆或离风;背风侧(外侧)毛线乱抖=收帆或向风。

WIND 风 luff 帆前缘 windward 迎风侧 leeward 背风侧 both stream aft 两侧都顺飘 = 正确
FIG 4.2Telltales: both streaming = correct trim · 毛线两侧顺飘=帆型正确
Coordinate · 配合

Sail and steer together: as you head up (turn toward the wind) pull the sail in; as you bear away (turn from the wind) let it out. Hands move in opposite directions — front hand and back hand working as a pair.

帆与舵要协同:向风转(head up)时同时收帆离风转(bear away)时同时放帆。两只手往相反方向动,前后手配合成一对。

Changing sides — tack & gybe 换舷——迎风转 (tack) 与顺风转 (gybe)

At any moment the wind is on one side of the boat and the sail is set out to the other. To zig-zag upwind, or simply to turn onto the other tack, you have to swap the sail across — and there are exactly two ways to do it, depending on which end of the boat you turn through the wind. 任何时刻,风都从船的某一侧吹来、帆张向另一侧。要想迎风之字形上风,或只是换到另一舷,你都得把帆换到对侧——根据让船的哪一端穿过风,方法正好有两种。

WIND 风 through the eye 穿过风眼 TACK 迎风转 bow passes through the wind 船头穿过风 · 帆轻轻换边 boom slams across 帆杆猛甩过来 GYBE 顺风转 stern passes through the wind 船尾穿过风 · 帆猛烈换边(小心)
FIG 4.3Tack = turn the bow up through the wind · Gybe = turn the stern down through the wind
TACK · 迎风转

Bow through the wind船头穿过风(上风时用)

  1. Sail close-hauled with good speed and look around for room.先在迎风航向上保持速度,环顾四周确认有空间。
  2. Call "ready about." Steer smoothly toward the wind (tiller away from the boom).喊"准备转向"。平稳地向风转舵(舵柄拉离帆杆)。
  3. As the bow crosses the wind, the sail flaps and the boom drifts gently across.船头穿过风时,帆开始抖动,帆杆轻轻地飘到对侧。
  4. Cross the boat facing forward; swap tiller and sheet hands behind your back.面朝前移到新的一侧;在身后交换握舵柄与主缭的两只手。
  5. As the sail fills on the new side, straighten up and sheet in.帆在新一侧吃满风后,把舵回正并收帆。
GYBE · 顺风转

Stern through the wind船尾穿过风(下风时用)

  1. Sail on a broad reach / run with the boom right out; check for room.在顺侧风/顺风航向上、帆杆完全放出时,确认周围有空间。
  2. Pull in some mainsheet so the boom is more central — it will swing a shorter, gentler arc. Keep the vang on.先收一点主缭让帆杆靠中——这样它甩过来的弧度更短、更温和。保持压帆器收紧
  3. Call "gybe-oh" and steer the stern through the wind (bear away).喊"转篷",把船尾转过风(离风转)。
  4. As the boom flips across, duck, cross the boat, and let the sheet run back out.帆杆甩过头顶时低头,移到对侧,并把主缭放回去。
  5. Swap hands, straighten the tiller, settle low. The boom comes over fast.换手、回正舵柄、重心放低。帆杆甩过来很快
Safety · 安全

The gybe is the move that most often capsizes beginners: downwind the boom carries full power and slams across head-height. Pull the boom in before you turn, keep your head low, and never gybe in a strong gust if you can bear away and tack around instead.

顺风转(gybe)是新手最容易翻船的动作:顺风时帆杆带着满满的力量、在头部高度猛甩过来。转之前先把帆杆收近,低头通过,大阵风中如果可以,宁可绕大圈用迎风转代替。

05

Force Analysis / 受力分析

Why does a push of wind from the side make the boat go forward? Because two forces team up: the sail turns wind into a push, and the daggerboard stops the boat sliding sideways — so the only way left to go is forward. 为什么侧向来的风能让船向前?因为两股力在协作:把风变成一个推力,稳向板则挡住船的横向滑动——于是剩下唯一能走的方向就是"向前"。

Wind 风向 / wind force Aerodynamic force 帆受的气动力 Hydrodynamic force 水的反作用力 Hull & weight 船体 / 重力
forward 船首 / 航向 ↑ WIND 风 F_air 帆气动合力 drive 推进 ↑ side 侧向 → F_water 水反作用合力 drag 阻力 ↓ ← 稳向板横向阻力 F_water = − F_air 等大、反向 → 合力为零,匀速直航
FIG 5.1Bird's-eye view · at steady speed the water force is equal and opposite to the sail force · 俯视:匀速时水的合力与帆的合力等大反向

From side-push to forward drive侧向推力 → 向前的动力

The wind's total push on the sail (F_air, coral) points mostly sideways. Split it into two parts: a small drive straight forward and a large side force to leeward.

风作用在帆上的合力(F_air,珊瑚色)大体指向侧方。把它分解成两部分:一个朝正前方的较小推进力,和一个朝下风、较大的侧向力

You're right to expect the water force to point the opposite way — it does. The water pushing back on the hull and daggerboard (F_water, teal) is, at a steady speed, equal and opposite to F_air. The two cancel, the net force is zero, and that is exactly why the boat holds a constant speed and course (Newton's first law) rather than accelerating forever.

你的直觉没错——水的合力确实指向相反方向。水对船体和稳向板的反作用力(F_water,青色)在匀速时与 F_air 等大、反向。两者相互抵消、合力为零,这正是船能保持恒定速度与航向(牛顿第一定律)、而不是一直加速的原因。

Look at it component by component: the deep daggerboard supplies a sideways grip that cancels the side force (the boat barely slips sideways), and the hull's drag grows with speed until it cancels the drive. The boat settles at the speed where drive = drag. Pull the daggerboard up and nothing opposes the side force — so the boat just slides off downwind.

逐个分量来看:深插的稳向板提供一个横向阻力,抵消侧向力(船几乎不横移);船体的阻力随速度增大,直到抵消推进力。船最终稳定在"推进力=阻力"的速度上。若拔起稳向板,侧向力就无人对抗——船便被风往下风方向横推走。

Heeling vs. righting — a see-saw倾覆与复正——一架跷跷板

That same side force, acting high up on the sail, also tries to tip the boat over (heeling moment). You fight it with a moment of your own: your body weight hung out to the windward side (righting moment).

同一个侧向力作用在高处的帆上,还会把船往侧面掀倒(倾覆力矩)。你用自己的力矩来对抗它:把身体探到迎风一侧的舷外(复正力矩)。

Balance the two and the boat sails flat and fast. When the wind gusts, the heeling moment jumps — so you must hike harder or spill wind. That is the whole job in Section 06.

两个力矩平衡,船就平稳又快。一阵阵风来时倾覆力矩骤增——你就得压舷更狠,或者"漏掉"一部分风。这正是第 06 节要讲的核心。

Balancing in Strong Wind / 大风中的平衡

A flat Laser is a fast, controllable Laser. When it blows hard the sail's heeling moment shoots up, so you must add righting moment (your body) and shed power (the sail). Keep the mast vertical and the boat sails itself. 船越平,激光级越快、越好控制。风一大,帆的倾覆力矩骤增,你就得"加上复正力矩"(身体)并"卸掉动力"(帆)。让桅杆保持竖直,船几乎能自己稳住。

FIG 6.1Hiking flat · the longer your body's lever, the more righting power · 压舷:身体伸得越远,复正力矩越大

Hiking — your engine of stability压舷——你的稳定性来源

Hook your feet under the hiking strap and straighten your legs so your back and shoulders hang out over the windward side. The further out your weight, the longer the lever and the more heel you cancel.

双脚勾住压舷带、蹬直双腿,让后背和肩膀探出迎风一侧的舷外。身体伸得越远,力臂越长,能抵消的倾覆就越多。

Move in steps as the wind builds: sit in the cockpit in light air → sit on the side deck in a breeze → full hike when it's strong. Come back in the instant the boat sits flat — don't over-flatten to windward.

随风力分级移动:微风时坐在舱内 → 有风时坐到侧甲板 → 大风时完全压舷。船一平就收回身体——别用力过猛把船压向迎风侧。

The gust response — three reactions at once 阵风来袭——三个动作同时做

REACTION 01 · 身体

Hike harder压舷更狠

Throw your weight further out to soak up the extra heeling force.

把身体甩得更远,吸收骤增的倾覆力。

eased out 放出
REACTION 02 · 前手

Ease the mainsheet放出主缭

Let the sail out so the gust spills off it — then sheet back in as it passes.

放出帆让阵风"漏掉",风过去后再收回来。

head up 向风
REACTION 03 · 后手

Feather up借舵向风

Steer a touch toward the wind so it blows off the front of the sail.

轻轻把船头转向风,让风从帆前缘"漏"掉。

Pre-set · 预先调好

Before it pipes up, flatten the sail to shed power: pull on cunningham (flattens the front) and outhaul (flattens the foot), and tension the vang so easing the sheet still spills the top. A flat sail in a flat boat is the goal.

风变大前先把帆调平来减力:拉紧帆领下拉(cunningham)使前部变平、拉紧帆脚外拉(outhaul)使下缘变平,并张紧压帆器(vang),这样放缭时帆顶仍能漏风。目标是"平的帆+平的船"。

If it heels · 一旦倾斜

Letting the boat heel makes it round up into the wind (weather helm) and stall — fighting it with rudder only slows you and can trip into a capsize. Cure the heel first (hike + ease), and the helm goes light again.

任由船倾斜,它会自己抢向上风("weather helm 顶舵")并失速——只靠拉舵硬扳,既减速又可能直接翻船。先治倾斜(压舷+放帆),舵自然就变轻了。

07

Capsize Recovery / 翻船后如何回正

Everyone capsizes — it is a normal part of sailing a Laser, not an emergency. The hull floats, and one person can right it in under a minute using the daggerboard as a lever. The golden rule: stay with the boat. 每个人都会翻船——这是驾驶激光级的正常环节,不是事故。船体会浮起,一个人用稳向板当杠杆,一分钟内就能把它扳正。黄金法则:始终待在船边。

mast & sail on water 桅帆浮水面 centerboard 中插板
STEP 01

Hold on, reach the board抓住船,游向插板

Surface and keep a hand on the boat. Check you're free of all lines and the mainsheet is uncleated, then move to the centerboard sticking out of the hull.

浮起后始终扶住船。确认没被绳索缠住、主缭已松开,然后挪到从船底伸出的中插板(centerboard)旁。

grab firmly 双手抓牢
STEP 02

Grab the centerboard抓牢中插板

Take a firm two-handed grip on the board, close to the hull. (If the boat has gone fully upside-down, pull the board to roll it onto its side first.)

用双手抓牢插板靠近船体的部位。(若船已完全倒扣,先拉插板把它拉回侧躺状态。)

stand on board, lean back 站板上后仰
STEP 03

Lean back to right it后仰把船扳正

Get your feet onto the board and lean your bodyweight back. The board works as a lever — the hull rolls upright and the mast lifts off the water.

把双脚踩上插板、身体后仰下压。插板就是杠杆——船体随之翻正,桅杆和帆离开水面。

climb in, sit, sail on 翻进舱、坐稳、起航
STEP 04

Climb aboard & go爬上船、继续航行

As the boat comes up it scoops you toward the cockpit — climb in over the side deck, sit down, sort out the tiller and mainsheet, and sail on.

船立起时会把你带向驾驶舱——从侧甲板翻进船里,坐稳,理好舵柄和主缭,继续航行。

If it turtles · 若完全倒扣

If the boat fully inverts (mast straight down — "turtle"), stand on the upturned gunwale and pull back on the centerboard to bring it onto its side first, then recover as above. The hull floats — never dive under it, and stay with the boat.

若船完全倒扣(桅杆竖直朝下,俗称"乌龟"),先站到翻起的舷边、向后拉中插板,把船拉回侧躺,再按上面步骤扶正。船体会浮——切勿钻到船底下,始终待在船边。

Safety & Glossary / 安全与航行术语

A short pre-launch safety checklist, then the words you'll hear on the water — every term used in this guide, in plain English and Chinese. 先是一份下水前的安全清单,再是水上常听到的词汇——本指南用到的每个术语,中英对照。

Before you launch · 下水前

1. Wear a properly fitted buoyancy aid (PFD).   2. Check the forecast — avoid offshore winds that blow you away from land.   3. Never sail alone; tell someone your plan and return time.   4. Know how to right a capsize before you need to.   5. Dress for the water temperature, not the air.   6. If in trouble, stay with the boat — it floats and is far easier to spot than a swimmer.

1. 穿好合身的浮力衣(救生衣)。  2. 查看天气——避开把你吹离岸的"离岸风"。  3. 不要单独出海;告诉别人你的计划和返回时间。  4. 在真正需要前就学会扶正翻船。  5. 按水温而非气温穿衣。  6. 遇险时始终待在船边——船会浮,比游泳的人好被发现得多。

One-line summary · 一句话总结

Keep the boat flat, keep the telltales streaming, ease in the gust and sheet in the lull — and when in doubt, let the mainsheet go. Everything else is practice.

让船保持平稳、让毛线顺直飘动,阵风放帆、风弱收帆——拿不准时,就松开主缭。其余的,全靠练习。
