Those numerous little sloughs really can get you lost very easily, especially when you can't see over the levy. They claim that there's 1,200 miles of waterways in the Delta, which obviously includes all the sloughs, but that's enough to get anyone lost. When we first started boating in the Delta we'd go just a short distance and I'd be following along on a map or chart. Next time, we'd go a little further and so on. After more than 20 years on the Delta, there are still numerous places we haven't been. A great investment if you can afford it is a GPS chartplotter; In addition to having the maps/charts on screen, it will show you where you are.

Do you actually wear your life preserver, or just have it on board.
The correct answer should always be yes, but it depends. You really need a life presever on when you're in the water, but it's too late to put it on after you fall overboard, especially if there's a current taking you away from the boat. If I'm in a small/open boat which would give me no time to react in the event of capsizing or being ejected from the boat, I always wear a life preserver even if I'm just fishing behind the house.
Here's a photo of forum staff member Jim Dick and me in my bass boat; You can see we're both wearing life preservers, although these are the inflatable type which are less bulky than most other types.
If we're on the enclosed bridge of the big boat and are in calm inshore waters, we don't normally wear life preservers although they're always nearby. But we wear them when we walk out onto the bow to put out fenders and lines in a harbor. Another good alternative for fishing is an inflatable fishing vest. If you call the USCG for help, the first thing they'll do is tell you to put your life preservers on.
Your pontoon boat is relatively stable in calm water, but it can get in trouble in a hurry if you're thrown a wake from a passing boat. So I'd be inclined to wear a life preserver if I were on your boat in the Delta, except possibly if it were anchored in a protected slough with no boat traffic to worry about.
In your years of boating, have you ever been been stopped or boared by the Sheriff's dept. or Coast Guard?
Yes, although for the most part they leave you alone unless you're doing something you shouldn't. The U.S. Coast Guard is unlikely to stop or board you unless they see a potential safety problem or a security issue. One thing that helps a little is we have the Coast Guard auxilliary inspect the boat and they attach a sticker to the boat certifying that it's passed.
When we've travelled to or from the bay and they're loading nukes at Concord Naval Weapons station, they have a 1,000 foot boundary around the ship. Unfortunately, that would put us in shallow water, so I always ask for an escort through the channel and past the ship. In addition to the USCG cutter sitting right there, it's a little unnerving to have one or two USCG gun boats accompanying you at 5mph. (They're carrying live ammo in those guns). But they're quite courteous, professional and helpful and are there primarily to protect the ship.
Don't mean to scare you, but you did ask ;D
