douse anyone have a breakdown of the weights of the parts on any beachcats?

idealy the the a class, f14, f16 or similar light ones but any other cats may be useful

eg weight of

hulls
mast
boom
sails/batterns
rudders/daggers
beams
and the rest of it

Attached a pdf containing the weights of my boat.
Values are not quite accurate due to a lack of an appropriate weighing scale.
Hull weights are particularly imprecise and the boat total weight is definitely to small. Lighter parts should be more accurate.

According to the class rules (see www.tornado.org) the minimum weight of a ready to sail Tornado is 155 Kg.
New Marstrom Tornados carry 2-3 kg of lead to make the minimum.
So if you own a recent boat your estimates are very likely correct. However a couple of figures are "strange":
1) you state that the stbd centerboard is Kg 4,80 and the port centerboard is Kg 3,40. Is there any particular reason to explain the difference? I cannot believe that Marstrom builds foils so differently.
2) you state that the boom weights 1,70 Kg. Does this figure refer to the bare section? Even in such case the section weights only around 0,70 Kg/m. Hence a "wall" thickness of only 0,15 mm. May you confirm?

For a A Cat here are some datas, according to what I remenber (carbon mast and front cross beam)
2 hulls = 2 x 16 kg
Front cross beam + striker = 9kg
Rear beam + circ track =7kg
Trampoline = 2kg
2 x Centerboards = 3kg
Rudder system = 4.5kg
Front& Lateral stays + trapeze= 2.5 kg
Mast + spreade & diamond= 11kg
Sail + batten + 3.5 kg
Boom =1kg

A HC TIGER has around 45 kg per bare hull and mast is about 23kg

155kg excludes sails.

It is a '97 boat. I am quite sure that hull weights are not correct by 1-3kg each. I just did not have a good weighing scale.

Originally the boat came out too light. In order to avoid putting so much additional weight (lead) under the main beam, the previous owner decided to fill up one of the boards with epoxy.
That's causing the weight difference.

The boom is a cylindrical, circular shape. Outer diameter is 45mm. Wall thickness about 1mm (maybe 1.5 ?), length is 2340mm. Material is aluminium. Weight also includes cleats and blocks for mast rotation outhaul.

I found this online one day, thought it was interesting data. Not sure if it is 100% but seems close.
weights and other data of beachcats to 20'

Interesting compilation. However, I doubt if a Prindle 16 weighs 150 lb. Most others I'm familiar with seem right. Was there ever a Supercat 18 (w/ 12 ft beam)?

They also listed a Hobie 13 and a Hobie 13 turbo

i was not sure of how accurate the list was, but i helped Chris load his p16 on his trailer a few weeks ago and the 2 of us lifted it without any problem.

Nacra 6.0...472??? <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" /> damn, and I thought our boat was a hog! Tell me that's not right.

I would bet it is pretty close, but I know my 5.2 is slightly lighter than the 350 listed.

The finished hull weight of the Alpha Omega F14 is 16kg (per hull), the mast weight rigged is 9Kg, the CF beams are - rear, 6.5Kg, front (with D/striker) 7.5Kg.
The all up sailing weight is 75 to 78 Kg’s

Anyone know when the weight chart was published?
Some of the numbers seem a bit high especially the A cats.
At the 2007 A class Worlds most boats carried correctors to bring them up to the 75kg.(165lbs)limit.

Hobie Cat weighs the hulls and marks (engraves) them prior to shipping. I'm not sure whether any attempt is made at matching heavier hulls to lighter components for the rest of the boat to keep the weight at or near minimum.

The average weight of a single H16 hull is around 70 lbs. A light hull is 68 lbs or less, heavy is 72 or higher. These are rough numbers, working off my last 3 new boats since 1997, and comparing to others over a beer.

The Hobie 16 is 320, not 340 (changed in 1983)
The Hobie 17 is 330, not 300 (never has been 300)
