An accident between a ship and small boat shows the importance of defensive boating

Aug 29, 2023

Today we’ll look at the story of a fatal collision last year off Puerto Rico between a USCG ship and a small fishing boat. The situation was tragic for all concerned, and legally the small boat was at fault.

So be careful out there and drive defensively on the water, just like you do on land.
