Engineers and Designers-
I'm going to try and draw a diagram attempting to describe the changes in center of gravity, or pivot point of a sailboat. The question of ballast will follow:
A=Mast, B=Boat, C=Keel
The ability of a sailboat to keep upright, at all times, even after a knockdown, is dependent on the boats ballast. Correct? If a boat looses its keel
, then over it goes. The punching bozo concept
no longer applies. Is it the center of gravity at play, or the center of some other factor. Disregarding shape, what determines the keel
weight? How is the waterline determined? Can you exceed the formula for saftey? Can you have too much ballast? Or, conversely, not enought ballast? Above/below the waterline? Must the ballast be at somepoint below the center of ??
If you've been to the Dominican, you'll understand this. What happens when I add a container's load of Bananas covering the deck
of a keeled sailboat with no water
in the tanks
below? (Which begs the question should you keep the tanks
full at all times when underway?) Do the heavy bananas shift the center of whatever its called? The pivot point, because they're on deck
? I know it does, but I would like to know some facts about this, from a provisioning
standpoint. What might be the do's and don'ts when loading a ship. As a rule
of thumb, do you store pillows above the waterline and canned goods and tools below? Does a freighter not tip because of its surface area above water
? Or because of its weight below the waterline? or a combination.
I guess you could use a metronome as an example. The sliding weight determines the tick-tock speed of the device. On a sailboat, is there a similar sliding point?
This probably sounds stupid but I'm serious, btw.
