Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.
i.e. the body suffers from an apparent loss of weight equal to displaced weight of liquid when wholly partially immersed in fluid. This generates law of floatation and thus law of sailor’s life.
We lose something ,apparently, every time we sail . We lose land fun, we lose quality moments, some of us lose love, and most of us suffer from an apparent loss of character. I believe, we lose almost as much as we displace. Thousands of tons of water. Subtract a gain of money and add apparent risk, divided by on board fun and multiply it by workload.
We have a perfect equation here.
