I'd like to see a pic of a giraffe swimming.

According to Malovich, and Drs Donald Henderson & Darren Naish, about nine feet.
One of the most significant papers ever published in the annals of science appeared recently; it deals, for the first time ever, with one of the biggest scientific questions ever faced by the scientific community, and uses cutting-edge technology and awesome powers of deductive reasoning and logic to reach shocking, paradigm-shifting conclusions. I refer, of course, to Don Henderson and Darren Naish's Journal of Theoretical Biology article "Predicting the buoyancy, equilibrium and potential swimming ability of giraffes by computational analysis".
Their study examines what happened when scientists placed a 'digital giraffe' in 'digital water'.

I bet the got a Government grant for the research.

“... Does this have any implications whatsoever for anything?
Making predictions about the floating and swimming abilities of giraffes is fun, but does it have any wider implications? For one thing, it perhaps helps make the point that we're increasingly able to test questions in biology using computational models and simulation, rather than experimentation on real animals. In the case of the question "Can giraffes swim?", we just aren't able to use real giraffes, so our approach is - at the moment - the only one we can use to test it ...
... Finally, this project is one of several I've been involved in that's gotten a bit of media attention; this attention means that the paper is going to be the subject of more content-free discussion on websites than is usual for peer-reviewed research. Let me assure all concerned readers that this research did not involve the frittering away of pennies otherwise allotted to cancer research or the detection of Earth-killing asteroids. As I've said before (and, given that this article is appearing on ScienceBlogs, I'm preaching to the choir anyway), it isn't widely realised how much work scientists do FOR FREE and FOR FUN, IN THEIR SPARE TIME. Rant over ...”

I do not believe in computational models or simulation. These are the same type of guys that developed formulas for derivitives ( financial instruments). I say we throw one into the deep end of the pool.

Is a bit like saying you don't believe in gravity.

How about one water skiing instead? 
Not as easy as it looks  .........but clearly less than 9 foot to float a Giraffe

Seriously. Why didn't they just throw a giraffe in some water? It couldn't be more than a few grand to make that happen!

Nah, tager, they're endangered - that makes the paperwork SO much more complicated! And even with plenty of grad students, that isn't free.
I'm thinking I've SEEN footage of giraffes swimming, but confounded as to where, can't find it online.
I do have this though:
Quote:
Average height of males is 17 feet 3 inches or 5.3 meters.
Average height of females is 14 feet 1 inches or 4.3 meters.
Largest recorded is 19 feet or 5.88 meters.
...
Giraffes have never been observed swimming, but have been found on some islands where the water was 14 feet deep around the island

You do the math...

vaguely on topic for sailing....
In an effort to at least pretend that this has anything to do with sailing... ; -D
I say that mast is WAY to steeply raked!
