The bags differ only really whether they have one or two closing flaps at the top, and I believe they all have two these days. Affects the mounting a little but not much.What are the different types of spinnaker bags? What are the mounting standards? Are there specific types for different sailing techniques?
These are all the same question, really. Or at least there is one answer.Why is 470 gear hard to find/expensive compared to other classes?
Why don’t you see the 470 class out on the lake? I thought it was a pretty popular class, should have seen at least one at home...
Why are 470 races hard to find? I would have to drive a bit to nearest... aren’t they an Olympic class?...
I have! I laminated some extra stringers on my boat when they were allowed at the time. It's not hard to do through the big hatches, but I wouldn't do anything like that to an old boat unless there is something actually broken and in need of repair.Has anyone reinforced a 470 hull by laying glass from the inside?
A furler has always been illegal in the 470, and it would be pretty useless as well. It's not used even in comparable classes which allow it. Adding one would probably throw the tuning off as well. And the jib has battens. Etc.Is it possible to role a 470 jib on a %110 furler or do I need a specific type of sail? .
Get a coach who knows the stuff. Find people in your area who are familiar with trapezeing (most likelly in the 420) and who can watch you sailing and tell you how not to do it. Anyone (such as myself) can give you the basics from a distance, but you need someone next to you to spot your mistakes, which you will be making a lot in the beginning.What’s the easiest way to learn how to effectively trapeze?
Yes. But at or below 60 kg you'll have a tough time.Can a crew of two ~230lbs (~100kg) be able to right a turtled 470? Crew of one?
This is one of the things that you can do, but isn't necessarily smart or even fun except as an occasional stunt. Don't try it while you're still learning the basics, with the spinnaker up, or in anything but light to medium winds.Can you sail solo, single trapeze, on a 470? While flying a spinnaker?
The mainsheet is the first safety valve, the jib sheet the next if it's really blowing. But what you described happens usually slowly enough in a 470 (no "slingshotting" as in cats or skiffs) that the crew has time to unhook... and step directly onto the centreboard.When a 470 becomes suddenly over powered, and the skipper fails to luff the sail, would the crew on the line be brought over the hull and onto the mast/sail? Is there a safety release mechanism for this scenario? ... I can see how this can become very dangerous very quick.
Once upon a time, I got into the 470 because it was the natural next step as a sailor, I had a good helmsman who was in the same situation, the class was active in this country on many levels, and there was a fairly good boat for sale at our club.Why do you sail a 470?
I would say both. The visible vertically-mounted hooks look like they are for the bags, and there's very likely another hook on each side for that, just out of sight under the mast gate.6 hooks around the doors. Are these mounting for the bags, or used for something else?
Yes - do it like other 470 owners do, that is, buy the parts individually. If you're getting a harness from Fogh Marine, you might as well include these in the delivery:Got any suggestions?
Not only is it legal, it's mandatory.a spring steel tongue that covers the top of the gudgeon, and can be released to remove the rudder (picture). Is this legal?
NiceOddly enough I was gifted the entire trapeze system for Christmas
Buy a couple of spare hooks and always keep one on the boat or in a pocket when you're on the water. The hook is supposed to detach completely in an emergency, so tying it anywhere defeats the purpose really. Losing the hook (or any equipment for that matter) is no fun, but it's an acceptable loss in a potentially life-threatening situation.The quick release, when pulled, actually let’s go of the hook entirely. (So in case of emergency, you will lose the hook definitely.)
Are there any other solutions to this that you know of?
I just call it the trapeze elastic... the class rules use "trapeze return system".I need to add hardware (what is this called?) to the hull to take up the slack from the shock chord retaining the wire in place. Do I need a backing board? Do they rivet into the hull? I included a picture of a 420 with the shock chord setup I had in mind. Is there an easier way? (Also, I may tie up the shock chord to the bottom of the for stay instead).
Don't connect the wire and the cleat permanently like that; use a shackle in between them. And slide the handle on the wire before doing the endI plan on cutting and crimping the wire thru and around the camcleat mounting hole (I included a picture of this as well), then slide a trapeze handle on top of that. Would regular ‘hardware store’ aluminum ferrule crimps (3rd picture) work/be strong enough? I’m also debating whether or not if I need a thimble loop as well (4th picture). How long should the wire be?
You might want to watch the Sailing World Cup medal races in Miami tomorrow (28 January): men's 470 start scheduled at 14:35, women's at 15:20. Live video: World Sailing TVThen you can of course watch stuff like World Sailing TV videos on Youtube
Short answer: brand doesn't matter (they all make more or less similar products), type and gauge vary a lot depending on the specific application.Is there a specific brand, or type/gauge of rope that is recamended?
I hope this shows the general idea clearly enough:What does “mounting” look like?
No, they're permanent equipment.Should the bags be removed daily?
Sand it, and then varnish. Repeat that a couple times (and a few more in worn areas), then wet sand it to get a smooth surface.stain, paint or oil?
Great, thanks! Nice to see how it was intended to be set up. Which brings up the question I've had in mind for some time: do you want this boat to be as close as possible to the original, totally modernized, or something in between? It would help in making choices if you had a basic fitting-out philosophy like that.These are a few pictures from a pamphlet that the previous ower had with the boat
It is legal to fit hiking straps anywhere in the cockpit, but it isn't very smart to lead them where a trapezing crew member needs to cross the boat...there looks like a hiking strap for crew attached to the trunk support, that can’t be legal.
With a trolley, down a ramp or a beach.How does this type of boat typically get launched?
The boat weighs 120 kg, so two strong-ish people should be able to carry it for some distance, especially if a third one helps with balancing at the bow. With four it should be pretty easy.Is the boat light enough to pick up without a dolly (with possibly 3 to 4 people)?
If you're going to build a trolley yourself, you will have to take the measurements for it yourself from your hull. The wheels should probably be just behind the traveller; just about any padding that doesn't wear too quickly is good, my Laser trolleys have plastic tube for the purpose and it works.Are there any requirements (such as length of sling, or type of padding) that I should be concerned about?
do you want this boat to be as close as possible to the original, totally modernized, or something in between?
Yes. That sounds very good. Do it.A local club is offering a very reasonably priced program that gives you access to their fleet of twenty 420s, daily and racing on Wednesdays.
Yes. The most important thing would be to get coaching, especially with the basics of trapezing. Does the club have qualified coaches?I figured that this opportunity may benefit me in learning skills about the 470, such as sailing efficiently with crew, and single trapping.
They're very similar - a 420 is like a 470 with half a metre cut off the bow and 25 % less sail area. (Historically it's actually the other way round: it's more like the 470 being an extended 420, as it was designed five years later.) The 420 likes obviously a somewhat smaller crew, and has simpler control systems. If you can sail either you can sail the other. It's not even much of an exaggeration to call them the "grassroots" and "elite" branches of the same class.I realize that the 470 and 420 are different classes... How different are these boats?
Apart from the weird custom of sheeting the jib with both sheets at once, I can't think of any.Are there practices in a 420 that are not suitable for a 470?
As you're in the United States, these boats are most likely C420s, which is a development of the simplified and heavier boat that Vanguard had built for the US collegiate market since the early 1970s. It has a spinnaker and trapeze, but the mast is untapered, and it retains the original deck arrangement (no forward tank) that the International class ditched about 20 years ago.I'm not sure whether the equipment is the "International 420" or the "Club 420" - I asked in an email. What is the difference between these two boats? Are they both single trap, symmetrical spinnaker one design like the 470? (I'm guessing that the boats are Club 420s as thats whats popular here).
