Couple of quick maths questions

Fuck me, geometry aint so straightforward  I'ma try and get my head round round it but it might take a few reads.

Ok, we're moving on to geometry.  Tricky.


You've got a right triangle with a single side of 150', which is AB, below

Before, you were simply going from A to B, where B is the zero point (meeting the ship).

Now, you're starting at A, and moving to C, which is the new zero point.

You're in luck, because a 45^o right triangle has a special property in that both AB and BC are the same length.
You're also in luck, because the hypotenuse can be calculated with the handy dandy formula

AB² + BC² = AC²

22500 + 22500 = AC²

45000 = AC²

The square root of 45000 is 212 (roughly)

So, now you're going 212 feet instead of 150.  Back to the formulas!

6 MPH = 31,680 feet/hr = 528 feet/minute = 8.8 feet/second
212/8.8= 24 seconds.

15 MPH = 79200 FPH = 1320 FPM = 22 f/s
22x24 = 528 feet

If you go on a 45 degree angle, start paddling about 530 feet away.  Make it 550, because who knows how exact your angle will be.

Eh, the math is what it is.  I just laid it out rather than give you the final numbers.

If it helps, I can draw a picture.

Nah, it's cool I got it now. I actually knew the sum of the two squares things, just hadn't realised that it could be applied to this.

I can't say if I'm absolutely or just relatively confused by most of/everything in this thread.  The only thing that reads for me is "quick".  As in I'd be the last to advise paddling in the wake of a tanker.  I think with a mass at that velocity in water, that you really want to reconsider your proximity.  I don't think that's the kind of undertow you can paddle away from?

[Ed.  I forgot you might be kite-surfing]

Some bodyboard wanker gone and beat me to it 



Pretty epic shot, tho. Need to get this set up...

More fun than they really wanted.

Dude is six foot off the lip. Okay he's bodyboarding (points deducted there) but it's still a pretty awesome shot. That's exactly the kind of fun he was shooting for. And the shot? That shit puts you on the map. If I get one like that in a kayak, there's customers, there's sponsorship. It aint up there with Michael Jordan but a mate of mine gets free boats from one of the manufacturers. Other guys get paddles, kit. Good enough for me.

[Junkenstein]

Don't get me wrong, I'm sure it was exactly what he was after. Just saying he probably had to change his suit when he got back to shore.

I'm guessing he's Scottish.
