You did something very important that day that a lot of us forget about doing you knew where Mark was going and you knew after not hearing from him something was wrong. It is vital to tell someone else where you will be while on the water and what time you expect to be back in. In the event of an accident like the one Mark had someone will come looking for you. It is something we all overlook but in the event of an accident it could be the one thing that saves your life.
