Isn't it worth more than most small nations?

Worth and cost are not the same thing. Both may be true though.

very light for its size being constructed almost entirely out of carbon fiber and epoxy resin, and exhibits very high performance being able to sail at 2.0 to 2.5 times the true wind speed

On November 8, 2009, the team announced that a rigid sail wing had been built for the yacht.[12] The wing was initially 190 feet (58 m) tall and some 80 percent larger than the wing of a Boeing 747 airplane; it was later extended to 223 feet (68 m).[13] The wing has a very high aspect ratio, meaning that it is very tall and narrow. It can change camber to adjust lift in order to optimize performance. The wing consists of two main elements, separated by a vertical slot through which air can flow. The rear element is made up of several separate sections, whose angle can be adjusted separately, much like the flaps on an airplane's wing. Thus the lift of the sail can be controlled very finely, both overall, and for each section.

On February 14, 2010, USA also won the second race, and thus the America's Cup, again by a considerable margin. USA was ahead by 0:24 at the start, by 0:28 at the windward mark, by 2:44 at the gybe mark, and by over 4 minutes at the finish. Its official finish time was 5:26 ahead of the defender because Alinghi had to perform a penalty turn, having entered the pre-start area too soon.[19]
Winds were 6 to 9 knots. USA reached the windward mark in 59 minutes, so its velocity made good was about 13.2 knots, about 1.65 times wind speed. The course was a triangle, so the velocity made good downwind was only 11.5 knots, about 1.4 times wind speed. USA averaged 26.8 knots, about 3.35 times the wind speed, on the faster first triangular leg

I grew up racing sailboats and cannot seriously imagine going 26 knots in one.

is shaft horsepower different too

How is it possible to sail faster than the wind?

1271's? I'm curious about the drive arrangement on that boat. The car ferries we built for Shelter Island in the 70's have a single shaft running through the center of the boat, with a prop and rudder at each end. The engine sits on a floating tensioner next to the shaft, and turns it with some sort of belt drive system.



Good to see that bilge alarm panels haven't changed in the last 30 years!

I don't care how big or expensive your yacht is. I don't care how fast your carbon-kevlar speedboat is. Somewhere in the Mediterranean, a man wearing Persol sunglasses is at the helm of one of these, and as long as that's true, you've lost.

Not sure of the engine model of these, but it's just one engine per shaft so there's three props at the stern. I haven't spent too much time in the engine room, though.

This is a Moth:



It's slowly evolved from a fairly conventional looking sailing dinghy to a minimalist speed machine. It's got only what it needs to have to be a boat, and absolutely nothing more.

They'll foil in about six knots of wind with if the driver is light and knows what they are doing, and I think the top recorded speed is in the 25 knot range. They're a little odd to be around because once they foil they're almost completely silent moving through the water, until the daggerboard hangs up on a big piece of kelp, then you get a lot of splashing and profanity.

Quite a few youtube videos, some of boats being passed like they aren't moving, and a number of demonstrations of their amazing lack of stability when standing still. Apparently they are somewhat tricky to learn to sail, and sadly there isn't really a used market for them in the US yet. Hopefully that will change soon and I'll be able to afford one, right now the cheapest new ones are in the $8-$10k range.

Why is it that all yachting magazines should just be renamed CGI boat magazine? Do any of these things ever get built?

cubicle gangster posted:

This is kind of off topic, but I work in CG and I'm friends with a freelancer who went nautical about two years ago. From all accounts, theres so much loving work out there he cant cope with it and is having to turn down clients regularly.

Anyone remember the Wallypower 118? It looked like a Bond villian's stealth yacht, and the 118 stood for the length... 118 feet.

I'm a little envious of the guys who get to make pretty renderings like that. All the modeling work I do just gets turned into construction drawings.
