Quinte Fishing

Dear Quinte fishermen,

I have two questions,

1. What do the following ratings mean on a floater suit?

50N bouyancy aid
75N inherently bouyant

2. Also, I was once told by a CO that a floater suit is only
counted as a PFD if it is worn all the time. I was told if
I planned to fish without the suit on I needed a regular
PFD that fitted me, on board. Is this true or does a floater
suit count as your PFD?

Thanks,

BATMAN
