320cc weights

[conehead39]

I AM REFERRING TO THE 320 CC ..............Scott Ellis,What is the difference (or WCC definition)in the total weight between the 320 CC with Suzuki Power DF300 and Yamaha 4.2L V6.
One uses the term estimated weight as tested ;the other something like approximate dryweight.( ???? ) What is that exactly?
I think the Yam/suz had a hard top.

How and why do we have different values when you test.

I am use to the FAA methods of weighing airplanes and airliners. There is no confusion there.
FAA Basic operating weight includes BOAT/Plane/Seaplane ,the engines mounted on the vessel,battery(s),engine oil,hydraulic fluid installed.
NO FUEL. Example A Dc10-10 weighs less than A Dc10-40 because the 40 has heavier Pratt Whitney engines.

Why can't we give a 30 mph cruising speed rpm and mpg for the two boats when they weigh the same amount,or as tested.Actually I would like data on ALL your cats at 30 mph=mpg?)

I really don't care how far it will go a 15 mph ,unless I am in an emergency,then it would be probably one engine out(failed)
Like I just stole it and was taking it to mexico.

Why can't a World Cat representative respond to meaningful posts on this site?

Our definition of dry weight is base boat(NO OPTIONS) plus the weight of the heaviest engine available for the particular model. This weight doesn't include any fluids meaning fuel or water. Our published dry weight is 9,600 lbs so the dry weight that Yamaha has is incorrect and should be 9,600 lbs and not 8,484 lbs.

Weight as tested = dry weight plus estimated weight of fuel, water, options, people and gear. This is a estimate as we do not actually weigh each item of gear we have on the boat during the test.

When a Engine manufacture performs a test on our boat they all will do the test based on performance at every 500 RPM. This is pretty much a standard procedure that they all will perform in a outboard application. Doing the test in this fashion will allow you to look at the data and determine a pretty accurate speed and fuel burn through out the whole RPM range based on how the conditions where that particular day.

Is this true .
Dry weight for 320CC is 9600 lbs and includes the engines.
this includes the base boat. OK what does the base boat include at WCC.
Hull and Cap obviously. Both Suz and Yam 3200cc had hardtops.Are they considered options?
How about Sea Star stearing ,helm(s) hoses ,rams ,and Sea Star fluid(8 lbs). is it included in the base boat.
How about those 4 batteries,Battery system switches,wiring harness,Instrument panel,throttle and shifts

you stated the "Our defefinition of dry weight is the base boat ( so I am asking what does the base boat entail)
plus the heaviest engine in this case 3200cc is 300 hp . Longest,shortest ,or mid size shaft (25In ) which is normally used.
Propellers, are they part of the base boat or do they come under optional equipment (hard to run a boat without one)

How about the ~7-8 quarts of engine oil.~ weight of `15 pints oil is ~ 15 pounds.According to your statement it is not in the basic dry weight
Gasoline.weight is determined by its tempurature . Lets say it weights 6.3 lbs /gal at 15C or 59 F standard day seal level.
At 90 deg F maybe 6.1 lbs/gal.
Now you can see 300 gal of gasoline in a 330CC is 18830 lbs at 91F. Water lets just use 8 lbs per gal. and we don't carry a lot of water .

How did the Yamaha Test get weight as tested? Is it wrong also.
It is not hard to weigh a boat. we weigh our 330CC everytime when haul out at Coral harbor Marina ,Islamorada on the motor boat carrier.
You just read the front strap strain gage and the aft strap strain gage ,combine the two . Our 33 bridge battlewagon CONTAGIOUS has weighs from 14,700 to 15,000
lbs.....

Here is the link to our Standard items and optional items listed on our website. http://www.worldcat.com/boats/center_co ... _equip.php

Base boat is the boat with power and all standard items. no options. Power includes rigging, props, steering and batteries

Yes the Yamaha test should be 9600lbs as dry weight. As I said before it needs to be changed and the weight as tested should also change with it. We will work on getting that changed.

thanks for your quick reply.I am beginning to see some clean water at the bottom of the bucket.

Do you have a WAG for what all the standard equipment weighs. I know there are lots of items.

Also from your above reply then new term "BASE Boat" and estimated,"APPROXIMATE dry weight boat,"are the same ~ 9600 lbs for both zuk and yam.
Includes engines,batteries,rigging,props,and steering.

"Estimated weight as tested" 11,511 Yamaha boat now wrong, could be varied by passengers,fuel on board,water in holding tank,safety equipment,etc.

I would prefer to just weigh the damn thing just prior to testing it.

You got to be kidding me!

Someone has WAY too much time on their hands!

Scott,
Thank you for all your support.
Like Capt Jim said ,I got carried away .
However the(weight) subject was always on my mind for numerous years.
Hopefully ,some other forum members learned something.I certainly did.

My aviation career influenced my judgement ,because of the aviation term Basic Operating Weight.
It is an FAA regulation term and it does NOT matter who makes the airplane.

On a side note, what did you do in aviation? Sounds like you flew DC10s. Were they KC10s?
