200 gallons of diesel, about 1,400 lbs, on a 7,000 lb boat with water ballast?

Doubtful.

Not to sweat it, judge has that covered.

No, on a 14.5 ton boat with 3 tons of lead outside, maybe another half ton inside.

[Robatoy]

This from a guy who thinks he can 20 knots out of a 40-foot displacement hull.

And of course you lost interest in anything I had to say because I continually kept whooping your ass by calling your bullshit and bad temper on a regular basis.

[salty]

It's been done. And not even a modern boat. The venerable Cal 40, which was introduced in the early 1960's. Sustained 15 knot runs, and they have hit 25 knots.

Of course, this involves surfing! They are still competitive in the TransPac.

[krw]

Diesel has a density about 70% of water. Negative ballast. ;-)

[Robatoy]

You mean planing.... I was talking about a displacement hull, like Jessica's

[Robatoy]

And here I thought I was haulin ass with a Hobie 16 @ 14.5 knots...

[Leon]

And here I was wondering why you would need 20 knots in something. ;~)

[salty]

Nope, not negative ballast. If it is inside the hull, it is applying downward force.

[salty]

The Cal 40 IS a displacement hull.

What boat is this? It certainly isn't "Wild Eyes". When Abby bought her she had tankage for 25 gallons of fuel and she hasn't mentioned adding additional tankage. I hope she's carrying some extra though--with a diesel heater and 25 gallons she's likely to run out of diesel before she runs out of cold. And Wild Eyes is not a 14.5 ton boat with 3 tons of lead outside. Neither is Jessica Watson's "Ella's Pink Lady" nor Laura Dekker's "Guppy" so what _are_ you on about?

[krw]

It's less weight than the displaced water. It has a net buoyancy. It will change the COG, though.

[Lew Hodgett]

Lets see, 3.5/14 = 0.25 ballast ratio.

I'll pass.

Lew

[salty]

You are confused. The water displaced by the weight of the fuel is equal to the weight of the fuel. When the fuel is inside the hull, it has no "net buoyancy". Your body is buoyant when floating in the water. Now take that body of yours and place it in a 6 foot dinghy. The boat will be riding lower in the water. If your buddy gets in the boat with you, it rides even lower. Three guys, and the boat may swamp. Where is this "net buoyancy"?

Not once have I stated that she didn't know what she was doing in her sailboat. The point I've been trying to get across all this time is that age, maturity and experience all contribute to how one makes decisions. That's an important factor whether you want to admit it or not.

[Robatoy]

You load up a boat with 40 tons of cork, and the net displacement of the boat is 30 tons....the thing will float away into the air!! Really!!

[Swingman]

Use 40 tons of feathers instead, and it would fly ... Really!! ;)

===============================

`````````````````````````````````````````````````` What about horse shit?

Lew

[Robatoy]

We ALL know that 40 tons of feathers is lighter than 40 tons of cork. And, in the case of a 30 ton boat, it will leave a 10 ton hole in the water. It will. Really! . . . . . Now... horseshit is heavier, so Lew's argument doesn't hold water... certainly not 10 tons of it.
