When the electrolytes from the water react with the metals like iron it reacts with them and corrodes the metal
So when we built our boat from iron it can corrode In the water due to this effect
In order to prevent this from happening we add a metal anode of a metal which is more active than the metal we are using
Here we are using aluminum which is more active than the iron and hence electrolytes attach aluminum instead of iron and hence save iron from corroding.
In this way sacrificial anode helps to protect the iron components of the boat.
I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.

1) A metal "X" is used as a “sacrificial” anode on hulls of salt water vessels made of iron. The effect is to reverse the oxidation of iron to iron (II) by causing X to oxidize to the X ion. Calculate the voltage (in V, to two decimal places) for this reaction if it takes place under standard conditions. The standard reduction potential for X is -0.57 V (minus 0.57 V). 2) Batteries are charged and discharged due to the...

The CuCu ions undergo reduction by accepting two electrons from
the copper electrode (cathode) and depositing on the electrode as
Cu(s)Cu(s). The reduction half-cell reaction that takes place at
the cathode is
Cu^2+(aq)+2e^−→Cu(s)Cu^2+(aq)+2e^-→Cu(s)
The electrons lost by the ZnZn metal are gained by the CuCu ion.
The transfer of electrons between ZnZn metal and CuCu ions is made
possible by connecting the wire between the ZnZn electrode and the
CuCu electrode. Thus, in the voltaic cell, the electrons flow
through...

An oxidation half-reaction is characterized by electrons appearing on the product side. The oxidation of aluminum for instance would be represented thusly: Al(s) → Al3+ + 3e- (1) An reduction half-reaction is characterized by electrons appearing on the reactant side.

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...
