What if we make a boat with different sails and make a system to change them quickly at appropriate situations?

If a boat was designed like a catamaran, where the air travels under the base, would it help the boat go faster? Would it also increase the lift?

# data[].attributes.body
We learned that in order for a plane to "lift", the high pressure point is below the object while the low pressure point is above the object.
Can the lower pressure point be below the object and the high pressure point above the object?

The keel stops the boat from moving sideways when attempting to move into the wind.

Like can we have three sails, different ones. One that is used with the wind (like the usual square thing), one triangular textile one, and one that is like a plane wing, and they all work in the same time, knowing that the square and the triangular textile one can be closed?

How would the shape of the keel affect the direction of the boat?

If the keel was more streamlined, does that mean that the boat will move more sideways, rather than forward?

What is the significance of an engine in boats in today's world?

What is the significance of an engine in boats in today's world?

# data[].attributes.body
In the past, boats did not have engines to rely on and could only use its sail combined with wind to "sail-verb".
Some boats today do not have sails because they instead have engines.
However,  some boats have both sails and engines.

So, the question here is if a boat has both an engine and a sail, does it work better than a boat with just a sail, or just an engine?

You think that if we put the sails (like the cloth thing) around, would it work, or would it fail miserably? Thing to ponder...

# data[].attributes.body
The knowledge of physics and motion would allow us to make a flexible sail and boat body that could adjust to conditions with low/high wind and maximise the available energy.

What if the sails are in a rectangular shape? Would that increase the force?
