Boats
As per Archimedes of Syracuse Principle a boat stays afloat because
its weight is equal to that of the water it displaces. The material of the boat
itself may be heavier than water (per volume), but it forms only the outer layer.
Inside it is air, which is negligible in weight. But it does add to the volume.
The central term here is density, which is mass ('weight') per volume. The mass
of the boat (plus contents) as a whole has to be divided by the volume below the
waterline. If the boat floats, then that is equal to the density of water appproximately
one kilogramper liter.If weight is added to the boat, the volume below the waterline will have to
increase too, to keep the mass/weight balance equal, so the boat sinks a little
to compensate.
It is always advisable to wear life jackets while boating even if you know swimming,
also wear helmets as boat may strike a rock at speed and helmet will save you. Never
go for unknown water areas without a Guide as there could be water animals of all
sorts. Emergency light and Oxygen Cylinder are must for large boats. You can also
buy Navigation Equipment if you are chrtering unknown water areas. Keep some packed
food specially water with you while going for boating on long routes. Also keep
some self defense products with you if you are going for Safari on a Boat.
