There is a lot of debate about whether waxing a boat's hull helps it go faster. Some people believe that waxing the bottom of a boat makes it go faster, but others disagree. Some say that waxing increases surface tension, which increases drag, slowing the boat down. However, waxing does keep the boat cleaner for longer, so a waxed boat will be faster than a dirty boat with no wax.

Waxing the hull of a boat creates a 'boundary layer' of water against the hull, which may make the boat faster
Waxing the hull of a boat creates a boundary layer of water against the hull, which may make the boat faster. This is because the wax keeps the boat cleaner for longer, which will make it faster than a dirty boat with no wax. However, some people argue that waxing the hull of a boat will slow it down because it increases surface tension and drag. It is also argued that a boat needs to stick to the water to go faster.

Some people believe that waxing the bottom of a boat makes it go faster
However, this is not necessarily the case. Waxing the bottom of a boat increases surface tension, which increases drag. This means that a waxed hull would be infinitesimally slower. The fastest hull is a smooth, clean hull with no wax.
In reality, waxing keeps the boat cleaner for longer. So, a waxed boat will be faster than a dirty boat with no wax.

Some people believe that waxing the hull of a boat will make it go faster. However, others argue that waxing increases surface tension, which increases drag, making the boat slower.
The argument for waxing is that it keeps the boat cleaner for longer, and a clean boat is faster than a dirty boat. Boats that set speed records tend to have a little chop, and their hulls are designed to direct air under the hull and lift it out of the water. These boats also wax and polish their hulls before every race.
On the other hand, some people argue that a waxed hull creates a "boundary layer" of water against the hull, which would make the boat infinitesimally slower. One person suggests that the boat needs to "stick" to the water, and that lightly sanding the hull would make it go faster. Another commenter agrees that the fastest hull is a smooth, clean hull with no wax.

A waxed boat will be faster than a dirty boat with no wax
It is widely believed that a waxed boat will be faster than a dirty boat with no wax. This is because waxing keeps the boat cleaner for longer. However, some people disagree with this idea, arguing that waxing increases surface tension, which increases drag. This would cause the boat to slow down as it would want to "stick" to the water. It is also argued that a lightly sanded hull would make the boat go faster, as the water would stay in the rough spots, creating more water on water than water on boat.

Boats setting speed records go faster with a little chop and the hulls are designed to direct air under the hull and lift the hull out of the water
Some people believe that waxing the hull of a boat makes it go faster. However, others argue that waxing increases surface tension, creating a "boundary layer" of water against the hull, which increases drag and makes the boat infinitesimally slower.
Boats setting speed records do go faster with a little chop, and the hulls are designed to direct air under the hull and lift the boat out of the water. This is achieved by advancing the throttle, which makes the planing hull go faster, lifting the boat and allowing it to zip over the waves rather than slogging through them.
The formula for hull speed is: Hull speed (knots) = 1.34 x √ hull length (at the waterline, in feet). For a heavy displacement boat to go faster than its hull speed, it requires a rapidly increasing amount of power for an ever-smaller increase in speed. This is because, as the boat goes faster, the crest of the second wave moves further behind the boat, causing the boat to dig and sink into its own "hole" in the ocean.
To overcome this, boats need to get up on the plane, where they skim across the water instead of pushing through it. This is easier for longer, slender boats, as they have a larger hull length relative to their width and weight, requiring less power to get up onto the plane.

Waxing a boat's hull creates a "boundary layer" of water against the hull, which increases surface tension.
The fastest hull is a smooth, clean hull with no wax. To achieve this, you can lightly sand the hull, or use a cotton rag and a little biodegradable soap to clean the hull before racing every day.
Yes, boats that set speed records do use wax. They also have hulls that are designed to direct air under the hull and lift the hull out of the water.
