question: Why can arrows shot from bows travel much farther in water compared to bullets which travel significantly faster?
comment: Because they have more mass and lower velocity, so they are less dramatically affected by the resistance of the same area of water.
passages: Bullets are generally designed to work in air, which has a very low density. The density of water is roughly 800 times higher than that of air at sea level, and that reduces the penetration of a bullet proportionally. A bullet might travel a mile (1.6 km) in air, but travel no more than a few feet (about a meter) in water. Expanding hunting or defensive ammunition, such as that using hollow point bullets, will penetrate even less, as the water is dense enough to cause the bullet to expand. By firing while in contact with the target, a powerhead does not waste energy on traveling through the water, but rather expends all its energy directly on the target.
   The size of the bow wave is a function of the speed of the ship, its draft, surface waves, water depth, and the shape of the bow. A ship with a large draft and a blunt bow will produce a large wave, and ships that plane over the water surface will create smaller bow waves. Bow wave patterns are studied in the field of computational fluid dynamics.
   The ballistic characteristics of MEA series ammunition allows the user to fire at an underwater target from above the water, or an above-the-water target from underwater, or from underwater at a target which is also underwater. This ammunition allows the user to fire from above the surface into the water at a very low angle of incidence—in some cases as low as two degrees—without ricochet. After entering the water, the bullet will continue its original trajectory. The user when aiming the gun needs to compensate for the refractive index of the water (roughly 1.333 for fresh water at 20 °C).
   BULLET::::- Large air spaces
   BULLET::::- Jet Ferry or Power Ferry (sometimes known as "Surfing")- Boaters may need to get from one side of the river to another without moving downstream. In a river with strong current this cannot be done without using river features as an aid. Boaters can use holes where the water is flowing upstream to move from one side of the river to another. If these holes or waves are on an angle the boater can quickly surf them across in a 'Jet Ferry'.

   BULLET::::- Arm: A "long throw" windlass has a longer arm so that the handle is further from the socket to give a greater leverage on stiffer paddles. If the throw is "too long" then the user, winding a gate paddle, risks barking their knuckles against the balance beam when the handle is at the lowest point of its arc. A sophisticated modern windlass may have an adjustable-length arm.
   But Belisarius placed upon the towers engines which they call "ballistae". Now these engines have the form of a bow, but on the under side of them a grooved wooden shaft projects; this shaft is so fitted to the bow that it is free to move, and rests upon a straight iron bed. So when men wish to shoot at the enemy with this, they make the parts of the bow which form the ends bend toward one another by means of a short rope fastened to them, and they place in the grooved shaft the arrow, which is about one half the length of the ordinary missiles which they shoot from bows, but about four times as wide...but the missile is discharged from the shaft, and with such force that it attains the distance of not less than two bow-shots, and that, when it hits a tree or a rock, it pierces it easily. Such is the engine which bears this name, being so called because it shoots with very great force"

   BULLET::::- The side profile of a squirt boat is very flat when compared to a whitewater kayak or C–1.
  
  BULLET::::- The volume of a squirt boat is generally less than half of the volume of a normal kayak of the same length. This often ranges from 24–35 gallons (90–130 liters) for a squirt boat, but 50–70 gallons (190–260 liters) for a typical kayak.
  
  BULLET::::- Squirt boats often have foot bumps that enable the boat to maintain an ultra-low volume while still providing room for the feet.
  
  BULLET::::- When in the water, 70–80% of the boat will be underwater.
   A hull with a blunt bow has to push the water away very quickly to pass through, and this high acceleration requires large amounts of energy. By using a "fine" bow, with a sharper angle that pushes the water out of the way more gradually, the amount of energy required to displace the water will be less. A modern variation is the wave-piercing design. The total amount of water to be displaced by a moving hull, and thus causing wave making drag, is the cross sectional area of the hull times distance the hull travels, and will not remain the same when prismatic coefficient is increased for the same lwl and same displacement and same speed.
   When used against underwater targets, an underwater firearm may have a longer range and more penetrating power than spearguns. This is useful in such situations as shooting an underwater intruder where the projectile may have to first penetrate a reinforced dry suit, or a protective helmet (whether air-holding or not), or a thick tough part of his breathing set and its harness, or the plastic casing or transparent cover of a small underwater vehicle.

   Bowfishing arrows are considerably heavier and stronger than arrows used in other types of archery and are most commonly constructed of five-sixteenth inch fiberglass, but solid aluminum, carbon fiber, and carbon fiber reinforced fiberglass are also used. Bowfishing arrows generally lack fletching, as it can cause the arrow to flare to one side or another underwater and they are not required at the relatively short ranges associated with bowfishing. Line is attached to the arrow by tying to a hole in the arrow shaft or through the use of a slide system.
