Air and Sea: two similar fluids

It is not really hard to understand the similitude between air and water since both are fluids. A hydrodynamic shape is by default aerodynamic, otherwise I would not bother writing these lines. Consequently I see a lot of aviation in marine activities and viceversa, always surrounded by the same adventurous spirit, the go ahead attitude that can exhilarate a man to the limit. Lets take a look at exhibit A and see some important characteristics that can make a great picture like this very one:

Wind is calm although it conveys a major strength as picked up by this tall sail and sometimes disguised by the clear skies that denote a pacific blow of wind. The obvious question is, why is the catamaran tilting anyways? well, there is a lot of momentum, a huge sail and a powerful steady wind on surface, that's why. What's my point anyways, well, what makes this picture great is the shutter speed setting that makes a clear statement when it comes to freezing the action and categorizing the action as a very dynamic sport. No surprise Bavarian Motor Works BMW is a key designer of these high end carbon derivatives-based structure that shares all the space age technology only Formula one drivers can enjoy these days, and of course a few sailing teams that strive to win a world class championship.
by taking a look to exhibit B and enjoying the view of a monster-size marine vehicle flying at wonderful speeds on wind power.

It looks like it is a scale model but the genuine golden shine of the impending sunset reflected on the sail proves the point and makes this image simply magnificent. My only and secret concern is the tacit discrepancy between the shape of the sail
and the trajectory described by the sea wake which is totally opposed to it. God only knows and lets just focus on the importance of having high shutter speeds in order to capture the essence of high speed dynamics under the broad daylight.
Finally, my last exhibit shows a closer look at the crew-members that among others are impeccable well dressed just like I mentioned before, like F1 drivers.

This particular shot would have been a disaster had it not been st to a higher shutter speed while st the action takes place during broad daylight. Always take advantage out of the daylight power and increase shutter speed to ranges around the 1/1000 of a sec and for no reason lower than say, 1/750" if your objective is to free-frame the action in outdoors, especially in the sea that allows for such a signature set of conditions.
I will deliver my next issue pretty soon so until then I wish you all the best.
