Consider getting a battery operated driveway chime. It is a simple motion sensor with a base unit. The remote sensor is battery operated, lasts for a year or more. The base station runs on battery or 110v. I get a good 160 feet of range out of mine but with clear line of sight you can get more.

I use this for my driveway but it might work out well if you put it under the boat cover. If someone starts getting into the boat under the cover it may be good at detecting that.

Rodney, that looks like a great solution for the Loc-R-Bar install, where did you get your brackets?  Nixon's Marine was at the sportsmen's show last night and suggested getting some milled out of billet and then using carriage bolts to secure them so there is no way to unbolt them with the bar in place.

Thanks,

Tim

I liked Darren's idea of a driveway chime.  I had a friend who used those and they seem to work well!

Thanks to Rodney's advice I have been able to make the brackets and install the Loc-R-Bar security device on Naomi & my aluminum Bass Tracker Pro Team 175 TF.  Now I can feel more comfortable taking the boat on trips longer than 1 day.
