90 percent of the boats I'm on are broken, about half of those their owner doesn't even know its broken. I run boats by myself on regular basis, I've got 35 years on the water professionally and run three to four boats on the water a week. I wear an inflatable pfd, tell at least one person where I'm going and how long I will be. I've got at least one back up plan in case the engine stops running. I have a phone and vhf. I leave against the current in case I need to drift back. I go at it expecting it will break or give me trouble, its my job to fix it. I will not go boating for recreation by myself, its just not enjoyable or safe. I've seen the results of way too many unexpected

Spare - you run boats by yourself all the time.....but you won’t go alone for recreation .
Not sure I follow but clear about the safety features. I use same plus I wear the personal locator ....
I fish with and without others, continue to do so as long as the Feds don’t create a law and mess it up.

I run boats inshore, near docks and facilities, for short amounts of time, with all the safeguards I've mentioned. I do not go near the inlet or beyond the jetties without someone else with me. I prefer to have someone with me even running inshore. I carry a fair amount of tools and diagnostic equipment with me JIC. Most often, when I'm running one, I have someone on standby with a boat in case I need assistance. It is not fun, its not relaxing, its work, its what I do. BTW, GPS, PLBs, etc fail pretty regularly. I've got one customer that fishes offshore by himself, he bought a clip on PLB that responds if hes too far away from the helm and will shut the engines off. After several false alarms, a call from the USCG and the system shutting his engine off for no reason. He had the system removed and returned it
