By having sufficient freeboard once the vessel's gross weight has been displaced. Freeboard is the height from water surface to the lowest point of the walls (gunnel) of the vessel. Any water that does come inboard (spray or wave over the side) needs to be pumped out of the vessel.
By keeping the water out. Don't exceed the boat's weight capacity and don't allow any holes in the boat.
keep it aboard the boat when in operation.
Keep clohrine levels at constant
The water displaced created a force of buoyancy sufficient to keep the boat from sinking. This is the same idea with steel ships. If you take a ball of steel and put it in the water, the steel sinks, but large battleships made entirely of steel float. Why? When as ship presses into the water, it pushes against the water on all points under the water's surface. The water pushes back, more weakly than the boat (otherwise the boat would sit on the water the way a car "sits" on land), but enough to keep the boat from completely sinking.
Weight used to keep the boat stable in the water. Old seagoing vessels, such as pirate ships use to have ballast stone which was kept in the bottom of the boat down the middle(keel) to keep the boat sitting properly in the water. Modern submarines use saltwater in their ballast tanks(big huge tanks located inside the hull) to enable them to sink and remain submerged
if the water is moving then it will exert a force on the side of the boat. Still water will not move a boat.
Sure, if it has enough air to keep the total density less than that of water.
easy - keep away from the rocks
that is where the water level is when the boat is in the water.
Removing water from a boat
The bird is a kind of "sea anchor" that is lowered into the water on a cable, on each side of the boat from booms out over the water. It is shaped sort of like a streamlined "bird" from which it gets its name. The birds keep the boat steadier in the water as it's moving and help reduce rolling in heavy seas.
