How far must a boat and a skier stay away from a non moving boat?
Local rules will apply.
How do you sail away in a boat on clubpenguin?
You must be in the January 2011 Wilderness Expedition. If you are, complete the maze, do the machine then build a boat and sail away on it. You will earn a rare party stamp if u do.

Does water temperature affect speed?
Yes, but the effect should be minimum. As water cools it becomes more dense, Meaning that there is more mass per volume. As a boat moves through a given volume it must displace some of the water. Since ( F = M * a ) the boat must exert a certain force to move an amount of water. If there is more mass in that certain volume the boat must exert more force, thereby slowing the boat.
What is the density of water vs density of a boat?
The density of pure water is approximately 1000 kg per cubic meter. It isn't, strictly speaking, useful to compare the density of a boat to the density of water. A boat can be constructed of material considerably denser than water (consider a steel battleship or aircraft carrier) and still float. What's important is that the boat must be able to displace a volume of water equivalent to the weight of the boat, without allowing the water to enter the boat. ---------------- Addendum ---------------- The answer your teacher is looking for: "The density of the water is greater than the density of the boat.". This answer is not correct in all cases. If the actual displacement of the boat (sans air) is used to determine density, all steel boats would be denser than water, and most motor boats would be denser than water. A boat which (sans air) is less dense than water cannot fully sink. Now for the next phase of comprehension: the boat has a degree of buoyancy not just in the water, but also in the air. To measure the total bouyancy (which is 0 while floating), you must understand that the mass of the displaced air (above water level) and the mass of the displaced water (below water level) is the sum of the mass of the air (below water level) and the boat (without air). Were the air denser than the boat, the boat would lift (sans surface tension) from the water and float away in the air.
How should you pull someone out of the water and onto a small boat?
If pulling a live person into a small boat you must instruct them to help as much as they can. As you start pulling the person in you must take the time to even out the weight by carefully leaning back. As you finally get the floater into the boat both of you must get back to the center boat. Otherwise the boat will tip.
What is the formula to calculate how many people can be on a boat?
No simple formula. When you add 100 kg to the boat, it displaces 100kg, ~ 100l water. You must then calculate how much lower the boat gets in the water, to displace that water. It would be easier, if the boat had vertical sides, like a barrel or a box, otherwise you need to do integration (calculus). If the boat is not rocking, and the water is perfectly still, you can put people into the boat, until the weight of the people equals the weight of the water displaced when the edge of the boat is at the edge of the water. But in real life, you must account for waves, wind etc. Then there is seating capacity, toilets, food etc, if we are talking about a liner or ferry.
When a mirror is used in lieu of an observer when towing skiers the mirror must have?
When a mirror is used in lieu of an observer when towing skiers, the mirror must have at least 78 square inches of viewing area and have a field of vision of at least 170 degrees mounted on the vessel.

In Virginia what must you do when operating a boat or PWC within 50 feet of a dock boat launch or people in the water?

What must you do to obtain an Oregon certificate of number for your boat?
Before a boat can be issued an Oregon certificate of number, the boat title must be obtained.
What is a plimsole line?
the plimsole line or mark was named in the 19th century . the line shows if the vessel or boat is over it is out of the water then the vessel or boat is not over but if it is in the water then the vessel or boat is over the weight and some thing must be taken off ! as it is legel to be over the weight that boat or vessel should be.
