When talking about past situations is it wrong to use "could with an infinitive" instead of "could have done"? In these senteces below and in conditional senteces such as "If I had more time I could have written two reports. Or "I could write."
1."Passengers could have taken other smaller transatlantic ships."
2."The captain could have chosen a more southern transatlantic route."
3."The owners could have pressed designers to include more safety flotation compartments."
- "Watchmen could have asked the captain to slow down due to fog."
