I would focus on the mental shaping in a safe environment (water) aspect.
<br>
<br>I found sailing to be very shaping. It teaches effectiveness (No time to argue needlessly in a race). Respect, for other sailors on the water (the old laws of seamanship, picking up a "swimmer" is more important than racing), Respect for the nature around you. The importance of preparation, before the race, etc etc etc.
