Is traveling in unsafe boats, with the traveler's knowledge of the probability of drowning, considered suicide, or is the drowned person considered a martyr?

Riding the sea while it is turbulent, or when one strongly believes there is no safety, is not considered suicide. However, the one who does so is sinful because he cast himself into destruction and exposed himself to peril. Consequently, he is not considered a martyr, and this is the most preponderant view among the scholars.
