My mooring is at least 10 degrees cooler on a summers night than at the dock.
I'm out just far enough where there are NO BUGS.
I can play music and have drinks with friends till the wee hours, no worries about keeping awake those people 10 feet a way.
There are exits from the mouth of the river due east and SSW from my mooring. This means I sail on and off the mooring regularly.
Access to my mooring comes with a T-head with water and power. I use it for repairs the occasional battery charge and water top up.
My harbor has a free pump out boat that I can even set up an appointment online and don't even need to be on the boat for the pump out (I choose to be there, but, it's an option).
My mooring is about 1/3 the price of a slip.
My Dink has wheels and I leave the outboard attached so I only need to roll it down the ramp.
Constant power at the dock.
Easier access to the car, marina head.
Easier to just stop by the boat for an hour after work and tinker with something.
Loading and unloading for a trip is pretty much a wash as I have access to the T-head.
Having a decent size inflatable with a reliable outboard is important. My inflatable will easily hold 1000 lbs. How much crap do I really need to go away for a weekend
