1. I have concerns for my boat left unattended in the slip for weeks at a time at a marina without round-the-clock office hours. I made a small sign on my cabin door that says, "In the event of any problems or concerns, please call Al or Meg at (916) XXX-XXXX. Many thanks from FlyWright." I have received a call after leaving my GPS receiver on and its lost-signal alarm sounded through the night in our covered slip. I'm surprised more folks don't place their contact info in a window of their boat.
2. For lighting help, I keep several of those ball cap-mounted clip LED lights around the boat. The cap keeps the sweat out of my eyes and the light provides hands-free task lighting in the ER.
