Talk:Sailing

Initial

I need to shrink the graphic.

• Done, with assistance from a Constable.

"History" and "Racing as a sport" require more work as I know almost nothing about them. But its a start.

Any comments?

Photos

I added one. There are many other wonderful free photos at Flickr of sailing. Here are a few:

line, not rope

I would say we should educate that there are only 2 ropes on a sailboat - "bolt rope" and "anchor rope." Everything else is a line, sheet, or halyard. We should also spell both ways of writing different sailing words. For example both Jibe and Gybe should be listed. -Tom Kelly (Talk) 17:20, 6 May 2007 (CDT)

Excellent start

Just wanted to say that. --Larry Sanger 13:57, 17 May 2007 (CDT)

Approval?

In my opinion this article is not quite ready for approval. Example issues:

• The history section is extremely short; article is not comprehensive
• The discussion of the difference between a boat and a ship doesn't seem important enough to belong in the introduction
• The rigging diagram, [1], uses a formula, a=(vf-vi)/t, which assumes constant acceleration. Also, I seem to recall hearing once that lift is more complicated than the fast-air-is-low-pressure principle; I think a physics and/or engineering editor should look over this section before approval.
• The article consists of a bunch of sections without a coherent narrative flow.

If that formula is wrong (I assumed that was the one), then could you tell me which formula it is so that I might fix it? Or is the formula so complicated that it's not even worth putting in the diagram? (Chunbum Park 14:16, 6 January 2008 (CST))

I guess the problem isn't so much the formulae themselves, but the introduction of symbols without defining them. For example, what's "m" and "a"? I think you mean the mass of the air and the acceleration of the air, but how much air? There's a flow of air, so instead of f = m a you should have something like (Force) = (air mass flow rate) * (change in velocity of air). A medium-level calculus-based physics textbook may help you understand what's going in. See for example section 3.5, "Momentum and the flow of mass", of Kleppner and Kolenkow.

I know that it is much more complicated than the Bernoulli's Principle but that's basically the main part of it - my physics textbook doesn't get better than that. (Chunbum Park 14:20, 6 January 2008 (CST))

I also disagree with approval.

Example of that bad narrative - "There are sailing organisations in almost every country, even when land-locked." - which is bad grammar.

It looks too much like a Wikipedia article. Section, dadada. Section, dadada. Section, dada. This isn't what an ideal Citizendium article should be like. Here, "Articles should be written to be read all the way through"..."they need a unifying plan, or a narrative, which lends coherence and flow and invites readers to keep reading" (not like section by section, as if in a curriculum or a learning course - it should be like a novel). "This means that articles should not be modular or mere collections of facts that can easily be reshuffled."

Also it has no bibliography - no citation. (Chunbum Park 14:29, 6 January 2008 (CST))

I think we should rewrite the introduction before approval. I would enjoy reading more flowing paragraph as an introduction. If we mention the types of sailing referred to - ice, para, regular, etc - we should also link to another article which talks about windsurfing, kiteboarding, and other uses of windpower over H2O.

nomenclature section

in the process of adding: bolt rope, boom vang,

I need to confirm before adding another use of clew. Isn't the corner of the spinaker that is opposite the spinaker pole called the clew? obviously this changes when you gybe. Also, if free flying the kite (shoot, spinaker), are both corners called clew? Tom Kelly 15:03, 6 January 2008 (CST)
