A Sailor's Guide to the Galaxy

Sailing Basics — a beginner's reference for new sailors

Home
This guide is a reference, not a sailing course. Local sailing clubs are a great place to get on the water, but most — including CLSA — are volunteer organizations, not schools. If you're seeking formal instruction, consider programs such as the American Sailing Association or US Sailing.

Points of Sail

A sailboat can't sail straight into the wind — but it can sail almost everywhere else. Drag the slider to turn the boat and watch how the sail trim changes. The wind is always blowing from the top of the circle.

NO-GO ZONE WIND
← turn to port  |  turn to starboard →
Close Hauled
The big idea: the closer you point toward the wind, the tighter you pull in the sail. The further you turn away from the wind, the more you let it out. When in doubt, let it out — ease the sheet until the sail just stops flapping (luffing), and that's your trim.

Parts of the Boat

Click a numbered dot on the boat (or a name in the list) to learn what each part does. This is a typical centerboard dinghy like the Highlanders, Thistles, and Flying Scots you'll see at Cowan Lake.

Who Has Right of Way?

Two boats meet on the lake — who keeps going, and who keeps clear? Work through these scenarios. These are the basics every new sailor should know; the full rulebook is the Racing Rules of Sailing 2025–2028 (PDF), but it all builds on these.

Racing Basics

CLSA races most Sundays plus holiday regattas. You don't need to be fast to start racing — you need to know where to go and how the start works. Crewing for an experienced skipper is the best way to learn.

1. The Start

Races begin with a countdown sequence of sound signals and flags from the race committee (typically 5 minutes: warning → preparatory → start). The "starting line" is an imaginary line between the committee boat and a mark or flag. Your goal: cross the line at full speed exactly when the start sounds — not before!

⚠️ Watch out: Cross early and you're "OCS" (on course side) — you must sail back and restart while the fleet sails away. When learning, start a few seconds late at a less crowded spot on the line. A safe start beats a brave one.

2. The Course

Club courses are laid out around marks (buoys), usually starting with an upwind "beat" to the windward mark, then reaching or running legs back downwind. The course board on the committee boat tells you which marks and in what order — and which side to leave them on (usually to port: leave the mark on your left as you pass).

Round marks like a pro: enter wide, exit close ("wide in, tight out") so you come out of the turn at speed and on the new course.

3. Racing Right-of-Way Extras

All the basic rules from the quiz still apply. Racing adds a few more you'll hear about: boats overlapped at a mark must be given room to round it; and if you break a rule, you can usually exonerate yourself by sailing clear and doing a two-turns penalty (two complete circles, including two tacks and two jibes). Doing your turns promptly is good sportsmanship — everyone fouls sometimes. The official rulebook is the Racing Rules of Sailing 2025–2028 (PDF) — Part 2 (When Boats Meet) is the part worth reading first.

4. Beginner Strategy (keep it simple)

Three things win club races more than boat speed: clear air (don't sail in another boat's wind shadow), fewer maneuvers (every tack and jibe costs distance), and sailing toward the dark water (ripples = more wind). Ignore the fleet drama, sail your own race, and watch what the boats that beat you did differently.

📋 Before your first race, read the club's Sailing Instructions and the Courses & Flags page — and just ask someone at the club. Sailors love explaining this stuff.

Five Knots That Cover 95% of Sailing

Practice these at home with any piece of rope until you can tie them without looking. That's not a joke — you'll often need them with cold wet hands while the boat bounces. Each knot below has the real tying video from Animated Knots by Grog.

1. Figure-Eight (stopper knot)

  1. Make a loop near the end of the line, crossing the end over the standing part.
  2. Bring the end under the standing part, then back down through the loop.
  3. Pull tight — it looks like an "8."
When you'll use it: tied in the end of every sheet so the rope can't escape through its block. First thing to check when rigging the boat. ▶ Video demo

2. Bowline ("BOH-lin")

  1. Make a small loop ("the rabbit hole") with the standing part on the bottom.
  2. The end ("the rabbit") comes up through the hole…
  3. …runs around behind the standing part ("around the tree")…
  4. …and goes back down the hole. Pull tight.
When you'll use it: the king of knots — makes a fixed loop that won't slip but unties easily even after heavy load. Attaching jib sheets to the sail, tying to a ring, securing almost anything. ▶ Video demo

3. Cleat Hitch

  1. Take a full turn around the base of the cleat.
  2. Make a figure-eight over the horns.
  3. Finish with a locking hitch: flip the last loop so the end is pinned under itself, pointing away from the load.
When you'll use it: securing halyards after hoisting sails, and tying up at the dock. The most-used knot at the club hoist and docks. ▶ Video demo

4. Round Turn & Two Half Hitches

  1. Wrap the line fully around the post or rail (the round turn takes the load).
  2. Tie a half hitch around the standing part.
  3. Tie a second half hitch the same way. Snug them down.
When you'll use it: tying the boat's painter (bow line) to a post, rail, or mooring. Holds under load, comes undone when you want it to. ▶ Video demo

5. Square (Reef) Knot

  1. Right end over left, and under.
  2. Left end over right, and under.
  3. "Right over left, left over right — makes a knot both tidy and tight."
When you'll use it: tying sail ties when flaking the main, bundling things up. Never use it to join two ropes under load — it can capsize and slip. ▶ Video demo

Capsize! (It Happens to Everyone)

Capsizing a dinghy is a normal part of the sport — every good sailor has done it many times. Cowan Lake is a friendly place to learn: warm in summer, no current, and a safety boat on duty during club events. Here's what to do, based on CLSA's own procedures.

The moment you go over

  1. Count heads first. Make sure skipper and all crew are accounted for and OK. Everything else can wait.
  2. Stay with the boat. Never swim for shore — a capsized hull floats, is easy for the safety boat to spot, and is your biggest flotation device. (You're wearing your life jacket, because you always wear your life jacket.)
  3. Watch for lines. Don't get tangled in sheets in the water.

Righting the boat

  1. Uncleat everything — main sheet, jib sheet, and boom vang. If the sails are cleated in, the boat will just blow over again the moment it comes up.
  2. Let go of the rudder and let the boat swing bow into the wind.
  3. Get to the centerboard. One sailor swims around and stands on the board, close to the hull, and leans back holding the gunwale or a jib sheet.
  4. Scoop method: in bigger boats like the Highlander, another crew member floats in the cockpit area and gets "scooped" aboard as the boat comes upright — their weight also keeps the boat from flipping over the other way.
  5. Once up: skipper takes the tiller and keeps the bow into the wind while everyone climbs in (over the stern or windward side). Then bear off slightly and bail.
⚠️ If the boat turtles (turns fully upside-down): the centerboard can slide back into its trunk — boards are heavy, keep hands and heads clear as it moves. Crew stand on the opposite gunwale and lean out using a jib sheet for support until the mast comes horizontal, then right as normal. On Cowan's shallower spots, a turtled mast can stick in the mud — that's a job for the safety boat, not you.

When the safety boat arrives

Let them run the show. They'll approach slowly, check that everyone is OK, and talk you through the plan before touching anything — usually approaching from the forestay side and lifting the mast while you handle the centerboard. If the boat can't be righted or sailed in, they'll tow you home (centerboard up, one person aboard sitting aft to steer). There's no shame in a tow; there's a lot of shame in hypothermia.

Sailing Lingo

Sailors have a word for everything. Search or scroll — these are the terms you'll hear on your first day at the club.

A Sailor's Guide to the Galaxy is a volunteer-built reference provided as-is, without warranty of any kind. It is not sailing instruction and no certification is offered or implied. Sailing involves inherent risks; nothing here substitutes for proper training, judgment, or safety equipment. Race scoring tools are provided as a convenience — the Racing Rules of Sailing and your event's sailing instructions and race committee are always the final authority on results. Don't panic.
