Posádka chce vyplout a přistát u břehu.

Because posádka means crew and it is grammatically singular in Czech.

Even though a crew is made up of several people, Czech treats posádka as one unit, so the verb agrees with it in the singular:

• posádka chce = the crew wants
• lidé chtějí = the people want

Also, posádka is a feminine noun, but in the present tense the verb form chce does not show gender.

Posádka usually means crew, especially the crew of a ship, plane, tank, spacecraft, or other vehicle.

In this sentence, because of vyplout and u břehu, it clearly refers to a ship’s crew or boat crew.

They are infinitives because they depend on chce:

• chce vyplout = wants to set sail
• (chce) přistát = (wants to) land / come ashore

This works much like English want to do something.

Structure:

• chtít + infinitive

Examples:

• Chci jít. = I want to go.
• Chce spát. = He/she wants to sleep.

In your sentence, one chce controls both infinitives:

• Posádka chce vyplout a přistát u břehu.

This is mainly a question of aspect and prefix meaning.

• plout = to sail / float / move on water
• vyplout = to set sail / sail out / depart by water

The prefix vy- often gives the sense of outward movement or a completed action. So:

• plout describes the activity of sailing
• vyplout focuses on the act of setting off

So in this sentence, vyplout is not just to be sailing, but specifically to sail out / set sail.

Yes. Přistát often means to land, especially for aircraft, but more generally it means to come to land / reach land / arrive at shore.

In a water-related context like this one, it can mean something like:

• to land
• to come ashore
• to make landfall
• sometimes to dock near shore, depending on context

Because the sentence also has u břehu (by the shore), the meaning is clearly about reaching land or shore, not an airplane landing on a runway.

Because the preposition u requires the genitive case.

The noun is:

• břeh = shore / bank

After u, it changes to the genitive singular:

• u břehu = by the shore / near the shore

So:

• base form: břeh
• after u: břehu

U usually means by, near, or at.

So:

• u břehu = by the shore
• literally something like at the shore / near the shore

It does not usually mean on the shore in the sense of physical contact; it is more about location near something.

A few more examples:

• u domu = by the house
• u stolu = at the table
• u řeky = by the river

A simply means and.

It joins the two infinitives:

• vyplout a přistát
• to set sail and land / come ashore

So the crew wants to do two actions.

Yes, that is the natural reading.

• vyplout = first set sail
• přistát u břehu = then reach or land by the shore

Czech does not need to explicitly say then here; the order of the infinitives suggests the sequence naturally.

Not completely. Czech word order is more flexible than English because case endings show grammatical relationships.

The neutral sentence is:

• Posádka chce vyplout a přistát u břehu.

But other orders are possible for emphasis, for example:

• U břehu chce posádka přistát. = It is by the shore that the crew wants to land.
• Vyplout a přistát u břehu chce posádka. = stronger focus on what the crew wants to do

Still, the original order sounds natural and straightforward.

The hardest sound here for many learners is ř, which is a special Czech sound.

břehu is approximately:

• b-rzhe-hu as a rough English-style guide

About ř:

• it is not just r
• it is not just zh
• it is a distinctive Czech sound somewhere between them

A very rough learner approximation is:

• say an r and zh sound together

You do not need to master it immediately to understand the grammar of the sentence, but it is worth practicing because ř is very common in Czech.

Yes, both are normally understood as perfective here.

• vyplout = to set sail, to depart by water
• přistát = to land, to arrive on land

Perfective verbs often refer to a completed event or a single whole action.

That makes sense in this sentence because the crew wants to achieve these actions as complete events:

• set sail
• then land by the shore

Their imperfective partners would be more like:

• plout = to be sailing
• přistávat = to be landing / to land repeatedly / to be in the process of landing

Yes. Depending on context, several translations are possible:

• The crew wants to set sail and land by the shore.
• The crew wants to sail out and come ashore near the bank.
• The crew wants to depart and make landfall by the shore.

The exact best translation depends on context:

• a ship
• a boat
• military crew
• nautical or literary style

But the Czech grammar stays the same.
