FAQ: Maritime Thrillers
What makes a thriller “maritime”?
These stories take place primarily at sea, on yachts, cruise liners, ferries, or riverboats, and often use the isolation and confinement of water-based travel to increase suspense.
Are maritime thrillers the same as naval thrillers?
Nope. Naval thrillers are usually military-focused (think submarines and warships). Maritime thrillers lean more psychological, mystery-driven, or survival-based.
Do these books include supernatural elements?
Some do! The Deep leans into horror and ghostly vibes, while others (like The Woman in Cabin 10) are grounded in reality but just as creepy.
