Can someone tell me the the class weight (one design)

of the Hobie Tiger. A boat sailed in the USA at a Hobie Event.



Thanks Fritz

Fritz,

Mininimum wt is 386 lbs. for NAF 18.

Hobie Eu website has the boat @ 180kgs which works out closer to 196 lbs. I have not weighed mine yet but probably will this season.

180kg=396lbs.

180kg * 3.281 = 590.58 Lbs

386 Lbs = 117.6Kg :Light Tiger (no mast and rigging maybe)

First you start with the following fact.

"The Pints a pound the world around"

There are 2 pints in a quart. A quart of beer therefore weights about 2 lbs. Depends on the spesific density of the beer and the temp in the room. Americans drink beer when it is cold and more dense.

Europeans being far less cultured, drink their beer at room temperature, ie less dense. Now Europeans drink metric beer. As we all know, the Germans drink beer from the time they are 8 days old and can drink more then us. Therefore they buy beer by the liter. Now being a practical people and realizing they only had 10 fingers, they invented the Metric system. Since a liter is 1000 ml and a ml of beer at room Temperature weights about 1.009 Grams a liter of beer weighs 1000.9 grams.

Add to this the fact that a fine malt beverage Called Colt 45 was so named because there are 0.45 Liters of beverage in a 16 OZ can, and the following conversion factors can be arrived at:



1 electron = 9.110 e-31KG

1 lb=0.4536 kg

1kg=2.205 lbs

so 180 kg= 396.82 lbs



IF your Hobie tiger was make up of just electrons, there would be a buttload of them.



Eric

Eric-

Very entertaining! The part about the beer, not the electrons!! Pull some strings this weekend!! DCS

where can i go to get the NAF rules? crew weight, tiger weight, other rules, etc. i just bought a tiger and have only raced hobie regattas in the past.

Congratulations with the new boat. You can find the website at http://www.naf18.com/.

Remember, a NAHCA class legal Tiger is a NAF18, but a Tiger modifed to NAF18 is not NAHCA class legal.

If you show up at Midwinters or NA Championships(Mega Event) with a NAF18 modified Tiger you will have to change it back if you want to race in the Tiger class.

Save all your parts.

Hi Sam,

I'm not clear on your post. If a Hobie Tiger meets the NAF-18 rules, what modification would be required?



Regards,



Roger

Hobie Tiger rules don't allow other manufacturers of sails. They also don't allow the self-tacking jib. I'm sure there are plenty of other rule differences but these are the biggies.



These features are allowed in NAF-18 and F18 racing.

Hi Mike!



There is a proposal to add a self tacking jib to the ONE DESIGN Tiger, among other modifications.



These can be found on the rules forum at



www.hobieclass.com



Hope to see you soon!!



Tom

Roger, you have my statement backwards.

A Hobie Tiger Class compliant boat IS automatically NAF18 Class compliant.

I was trying to point out that IF you modified a Tiger to some NAF18 rules, it COULD become non-compliant to the Tiger class rules IE: blades and boards by Hobie Corp., no tapered lines, etc..



Funny thing, I am reading the Tiger class rules and it says that "Replacement blocks or fittings shall not be constructed of exotic materials such as carbon, titanium, etc". Many of us are using the new Harken carbon blocks and they are CHEAPER, lighter and stronger than the old style blocks. EARTH TO HOBIE!!!!!

Hobie Tiger is a one-design class but as soon as hobie decides to go with new spreaders, new squaretop, selftacking jib, new boom outhaul setup and other goodies; Hobie corp itself just changes the rules of the ONE-DESIGN class to allow these changes.



I say "ONE-DESIGN" is only a lip service with respect tp Tiger. So forget this "One-design" crap and go formula all the way.



Wouter

Sam,



What do you mean by your statement, "Many of us are using the new Harken Carbo...", did you get a Tiger? Is there something you aren't telling us?

Anyway, Harken Carbo blocks are not made of carbon fiber. Its just a fancy name for the new type of plastic composite that they mold the blocks out of. My Tiger came from the factory with some carbo blocks, so how could they be illegal? Its my understanding that Harken will be phasing out the old blocks anyway.



Dennis

Wouter,



How does updating equipment on a boat make it no longer one-design? If that is true, then how does the Tornado class consider itself "THE" one design catamaran? They have been updating the Tornado for over 30 years, yet they are still considered one design. Am I confused, or should the Tornado class be called Formula 20 with a hull shape and foil restriction? Because those are the only things about that one-design that haven't changed over the years.



Dennis

Dennis,

You know I don't have a Tiger, but I am using carbon blocks.

And YES, thay have carbon fibers in them. That is why they are called COMPOSITE. I spoke with Peter Harken a few months ago and he explained that they had finally figured out how to mold products with long fibers in them. He specifically stated that you could burn off all of the plastic and end up with a pile of long carbon fibers.

My quote was from from the IHCA Tiger Class Rules website.

My comment was pointing out the fact that their rules don't agree with the boats they sell.

Which is class legal?

Whatever you buy from the dealer or whatever complies with the rules?

If someone without carbon blocks protests you at the Mega Event, can you PROVE you bought the boat with them on it and therefore ARE class legal?

What if you replace just ONE of your old blocks with a carbon, are you still class legal?

Remember, this is the bunch of idiots who wouldn't let us splice smaller lines and now we can't even use the tapered lines.

It's your boat, run what you want.

***From Harken Website

We designed our 75 mm Carbo AirBlocks for speed. Made of high-strength engineering plastics, the single weighs in at a very light 6.9 oz (195 grams) - including the shackle. Doubles and triples aren't much more! The strength-to-weight ration on these blocks is extremely high. They are the first all-plastic blocks with a safe working load of 1,200 lbs.

*** End Harken web site



Note: the last sentence "First All-Plastic Blocks "



I wonder why they would not want to advertise that there is carbon in them? In fact when I do a search for "carbon" on their web site, I only find reefing and furling systems for much bigger boats.... I don't understand? Sam, am I looking at the wrong blocks?



Thanks

The Tornado is often considered to be a Formula class in EU. For example multiple manufacturers can make tornado's and sell them for racing. However Marstrom competed all others out of business. The tornado class has very strickt formula rules and is strcikter than say F18 for it rules on hull shape too.



Wouter

I know what Peter Harken told me.

I guess the phrase "all plastic blocks" refers to the fact that these "Carbo" blocks don't need the steel, load bearing sideplates that the old style blocks have.
