After reading the passage containing the situation with Colin and Cole, we can say that the type of irony demonstrated is:
Situational irony.
<h3 /><h3>What is situational irony?</h3>
Situational irony happens when the outcome of a process is completely different from what the audience and the characters expect.
<h3 /><h3>What is the irony in this situation?</h3>
This situation is ironic because, since Colin and Cole spent so much time learning how to surf, we would expect them to have a great time when they finally went surfing for the first time.
Instead of enjoying the results of their training, one of them broke his board, and the other was eaten by a shark. Therefore, we can say the outcome was completely different from what we expected.
