This document discusses accidents associated with marine environments. It covers accidents that can occur when crossing surf, in bad weather like fog or major storms, and those related to navigation such as loss of power, loss of way, grounding/running ashore, and collisions. Small fishing vessels are particularly vulnerable to these accidents due to lack of equipment like radar and limited supplies. Causes of accidents include poor visibility, strong winds/waves, mechanical failures, improper lookouts, and fires from gas leaks or sparks. Proper safety procedures and equipment could help reduce these accidents for small craft.
