The Helm

A boat, a breeze, and a chart that means what it says. No score, nothing to win — only trim, stream, soundings, and the slow business of getting to know a rig.

Force 3, steady · no stream · deep water — Trim, the points of sail, and the tack.

Rigging her…
The word TG

Call the crew before the boat crosses the wind.

The hand on your shoulder

The water will tell you what it thinks of your trim; when it matters, you will read it here.

Sailing directions

The Sound

Open water and a kind breeze. Nothing here will hurt you; everything here will teach you.

Work to windward to the North Cardinal and run back to the pin. Watch the luff: ease until it lifts, then sheet until it just sleeps.

Try both tacks. In the lug, feel the difference the mast makes on port.

North Cardinal — Dead upwind of the pin — you cannot sail to it in a straight line.

The Pin — Home. Come back downwind and mind the gybe.

The boat

Standing Lug Daysailer

The boat of Plate I — light, quick to answer, and honest about every mistake. She has a good tack and a poor one, and she will capsize if you let her.

Port tack presses the sail on the mast — expect her a shade slower and lower than on starboard.

The board is her grip on the water. Up, she slides; down, she draws a metre.

She is a dinghy. Past thirty degrees of heel you are borrowing time.

10.5 m² working sail · 320 kg all up · hull limit 5.1 kn · draws 0.25–1.05 m

Reading the instruments

Two winds, two speeds, one bottom

The dark needle is the true wind, over the water. The orange one is the apparent wind — true wind bent forward by your own motion — and it is the only wind the sail ever feels. The faster you go, the further forward it draws.

Speed through the water is what the hull feels; speed over the ground is what the land sees. In a stream they part company, and the dashed blue line on the chart is your real track. The sounding is the water under you; the draft is how much of it you need — and the parts you are handling are the ones drawn and named in the Rigging Atlas.
