Joe,

This web site says water is 8.34 lbs/gallon.

This web site says water is 8.33lbs/ gallon and gasoline varies from 5.8 to 6.5 lbs/gallon.

Larry-

I based the conversion on the oversimplified fluid ounce relationship of water volume to weight, which was found to be in error as the history of measurement unfolded. A fluid ounce of weight was found not to actually weigh one ounce, but slightly more, as more exacting measurements were taken and comparisons made between the evolving fluid volume measurement and weight systems.

I once read about the whole messy and quite boring history of the development of the different Western (European/Occidental) measurement systems, and it's about as interesting as this discussion, and something not worth repeating unless one is bored stiff, stiff with boredom, or simply a bored stiff.

I considered the eight pound number to be precise enough for the conversion of the recalled figure of 110 gallons, which wasn't a "for sure" figure, anyway.

The differential ratio of 8 vs. 8.33 lbs is 0.04125 or 4.0125%, close enough for a guess as to the weight of the gas once I had seen the figure of 110 gallons, and realized this was like having two 55-gallon oil drums of fuel in the ass end of the boat along with the motors. The 4.125% difference at approximately 660 lbs =27.225lbs, hardly enough to loose sleep or drop your pants over.

Your statement that "gasoline varies from 5.8 to 6.5 lbs/gallon" still puts my simplified conversion number of 5.9 within the ballpark for our purposes of conjecture since we're not dealing with rocket fuel, science, or mentality here anyway.

Dan-

Thanks for the support and being anal and contributing to the cause. Every little bit adds to the pile of information that threatens to envelop, overwhelm, and enrich our lives. Maybe it will all help us grow beautiful flowers in the end! :rose :rose :rose

I take back my inference that you have too much time on your hands. Just not enough meaningful work, perhaps.

Maybe you, Larry, and I should form a club along with other C-Brats of similar interests in preciseness and perfunctory persuasion. We could resurrect slide rules, pocket protectors, crew cuts, and horned rimmed glasses along the way. Those were the days!

Tucker-

Follow your own advice and keep your life jacket on. It's getting deep around here!

Joe. :lol: :thup
 
lemme get this straight...three pages on the weight of water, and I'm the one with too much time on his hands?:roll:.......... OK, so I really did enjoy it, I admit it.. :?
 
Joe,

I'm not attacking your computations, I just always remembered water at 8 1/3, so when I saw 8, I wanted to be sure I don't have brain fade! LOL :teeth

I find it interesting that gas varies by 0.7lbs/gal which causes a 100gal load to change by 70 lbs! :crook

MartyP,

Come on now, it's only the last 8 posts about water!! :sad
We Brats have come a long way since the beginning of the C-Brats, we can almost stay on topic! :wink
 
Dan,

Does that mean that I need a 'stern lifting' propeller? :lol: :roll:


PS: Perhaps next year you should come 'outside' and join us at the Seattle BS and CBGT! :smile
 
For anyone interested the old incarnation of the 26 Venture had two 55 gallon gas tanks for a total of 110 gallons. I was told that it got "almost" the same fuel economy as the 23 Venture. I'm guessing that would mean 3.25-3.5 smpg in the real world with a 135 or 150 OB.

Another strange spec on the C-Dory sight, they state that the Venture 23 has a 20 gallon water tank and the 26 has a 17 gallon water tank. The old incarnation of both the 23 and 26 had 30 gallon water tanks in the bow. I don't know why CD would change this. I suspect this is another website typo.

Bill
 
Here's an idea, :smilep

C-Dory should hire Dan and Joe to check the specs of things like gas and water tank size, fuel economy, boat weights, etc. The factory could pay their airfair, put them up in a hotel and pay them a consulting fee. :wink

Then their web site could be up to date and accurate, and Dan and Joe could get a vacation in Seattle. :smile

Larry-

I know you're not attacking me because all of us save our attack modes for use on DogOnDan, who, I've just heard, was the Mechanical Engineer who designed the ship that had its front fall off! :smileo (But don't repeat that to anyone, because Dan's in charge of the Alaskan Pipeline and is getting paid a bundle to stonewall it on safety issues like that Austrailian Senator on the video clip.)

By the way, what was the original topic of this thread, anyway? :disgust

Joe. :teeth :thup

Well, when I looked at the V23 at the boat show, I'm sure it's fresh water tank was mounted under the rear dinette seat, not in the bow. So, it looks like at least some things have changed from the old layout. I wonder what else they tinkered with...
 
Are you sure that wasn't the water heater under the dinette seat?

Maybe CD changed the tank for money reasons? Or to save labor? The 30 gallon tank under the V berth was a great idea. It saved space in the cabin and moved weight forward for a better ride and better fuel economy.

Bill
 
The water heater on the V23 that I looked at was an "instant on" 120v unit located under the sink, right next to the inverter. There was no heater tank on board, and the areas under the mattress in the v-berth were all empty.
 
AK Angler, did you get a look at the brand or current draw on the water heater? I am considering removing the water tank type heaters and adding a 750 watt flow thru heater. The tank is fine at the dock or with a 2000 watt generator--but when at anchor, not much help, and considerable weight.
 
No, I don't remember what make or model. Sorry.

But it is interesting that the factory site lists an instant-on heater for the V23 and a 6-gallon heater for the V26. Both are listed as running off of shore power.

V23: water tank = 20 gallons fresh water on board
V26: water tank + heater = 17g + 6g = 23 gallons fresh water on board
 
The 23V that they had at the Portland boat show had an InSinkErator installed for the instant hot. It looked and probably is the same one under my kitchen sink at home. I went to there website, 750 watts/6.25 amps. They also had a faucet that automatically mixes the hot and cold for hand washing. The only thing I was questioning with the standard faucet is if the tank is turned up to almost boiling water it would be hard to use the water for anything other than cooking. I guess you can adjust the tank temp. for what you want. Hope this helps

Bob,

Do you think the Instant Hot would work for the shower as a flow thru device. When I get home I am going to test my unit. Will post the results.

Michael
 
Yes, I do think that the InSinkErator 750 watt would work as a flow thru. I take very brief showers on boats--just wet down, soap up, with the water off, and quick wrinse--usually about a gallon. The water doesn't have to be "hot"--but Warm is nice. We often use a sun shower or heat some water on the stove, and put into the sun shower, if we don't have a generator or shore power. We only have a 1000 watt Honda for the CD 25--and the 750 watt unit would work fine for that. This will also open up more storage space in the 25. I would plumb in before the hot water for the shower is "T" ed off.
 
Now for another twist... The factory has pulled the performance data for the Venture 26 off of their website. The following comment is in its place:

Please Excuse me, the performance chart I just removed was a space saving idea. We will be updating it later.

I don't get it. What is going on over there? Are there any factory reps participating on this site any more? Can we get some real data? Please.
