Orange II (dye)

Orange II is a vat dye is a dye that has the mordant and the dye added together and so the final reaction between them produces the dye. The chemical structure for orange II is C17H14N2O The structure of orange II has double bonded oxygen and this has a negative charge and it means that the carbon that it is bonded to has a positive charge.

This should be sourced and placed at Orange II (dye), this article is about the sailboat. - Eldereft ~(s)talk~ 14:59, 29 February 2008 (UTC)

Sail faster than power?

I assume that a sailboat can go around the world faster than a powerboat because powerboats need to stop for gas? or in order to conserve "gas mileage", powerboats need to operate at a slow speed? or because sailboats are lightweight and on the high seas just go fast? All three? Obviously, the overall speed is a combination of all factors, but which one leads to the unexpected "sail beats power" answer? This article is a good place to put the interesting answer (that I don't know). If the Earthrace powerboat was built to show off renewable resources by setting an around the world record, it sort of gets a renewable resource FAIL doesn't it? —Preceding unsigned comment added by 96.224.171.106 (talk) 16:06, 7 January 2010 (UTC)

The biggest factor is that this boat can't carry enough fuel to get around the globe without needing to stop for fuel. And since they need to stop for fuel, they need to keep near land. Sailboats don't need fuel so they can sail in the southern ocean and end up traveling a shorter distance. Earthrace stayed fairly near the equator and went through the Suez and Panama canals. Orange II sailed south from France, around the Cape of Good Hope, went east to round Cape Horn and then transited north to the starting point. Until someone tries for a record with a boat powered by a nuclear reactor and which is seaworthy enough to tackle the southern ocean, sailboats will dominate. I suspect a nuclear submarine could easily beat the Earthrace record, and perhaps even Orange II's record, and perhaps already has (see USS Triton (SSRN-586)). Addendum: a bit more research showed that Earthrace travelled about 24,000 nm, and that a record circumnavigation for a sailboat must travel 21,600 nm or more. So there is a 10% distance advantage for the Southern Ocean route, plus not having to stop at all certainly helps.--Paul (talk) 16:42, 7 January 2010 (UTC)

Instead of refueling at land, strategically positioned tank ships could be used. Of course, a submarine would still be the preferred vehicle, as it's independent of weather conditions (moderns submarines are faster when submerged than when surfaced, so the journey would be performed "under the sea") and can probably maintain full speed for almost the entire journey, if it's nuclear powered. At a speed of 35 knots (or more), it might be possible to race around the earth in one month (although it would be beneficial to pick a month with 31 days). --62.156.253.205 (talk) 15:42, 21 July 2011 (UTC)
