What does luffing mean in sailing?
In sailing, luffing refers to when a sailing vessel is steered far enough toward the direction of the wind (“windward”), or the sheet controlling a sail is eased so far past optimal trim, that airflow over the surfaces of the sail is disrupted and the sail begins to “flap” or “luff” (the luff of the sail is usually …
What is the best shape for a sail?
The best shape for acceleration has the draft fairly far forward. Upwind — When a boat is sailing into the wind, you want sails that are relatively flat. Flatter sails reduce drag when sailing upwind and also allow you to point a little closer to the wind.
Why are ropes called sheets in sailing?
Mostly ropes are used in the rigging of a boat and are called sheets or lines. Rope is the generic term because in days of yore all of the rigging on a sailing ship was made using hemp rope.
Why is a boat rope called a painter?

It is then proposed that the origin of painter lies elsewhere than in a Middle English derivative of Old French or Anglo-French *pendeur, *penteur ‘hanger’.
Where do telltales go on a sail?
Typically, a tell-tail is on a port and a starboard stay. Tell-tales attached to a sail are used as a guide for trimming (adjusting) a sail. On the mainsail tell-tales may be placed on the leech (aft edge) and when trimmed properly should be streaming backwards while on a beat (upwind).
How do you know if your sail is blown out?
Notice if any of these things seem true: 1. The boat seems to heel more than it used to at the same wind speed. 2. It doesn’t point as good or the jib is luffing when you’re trying to keep up with someone else on a higher tack.
How do luff telltales help in sail setting?
Telltales are a very powerful tool to help with sail trim. … Luff telltales show what is happening with the wind as it goes over the luff of the sail. Instead of waiting for the sail to luff and slow you down, using the telltales allows you to correct the sail trim before the sail flaps.
