I live WAY out in the country - that "used to be" safe. Leave your front door unlocked
whenever you left for a few hours or the whole day.
Now, with the Disney Attractions and Central Florida booming like gangbusters,
nothing and nobody is safe anywhere anymore.
The crack heads steal very expensive tractors and 4-wheelers right out of the yard.
Home invasions are becoming more prevalent, which is scarey.
I keep a padlock on my trailer tongue which is only a deterrent to someone without a
18v grinder or sawsall.
the motor is thru bolted to the transom. I keep my FF inside the house with my rods, reels and tackle boxes.
NOTHING of value is left inside the carport. (I don't have a secure garage).
Some of my neighbors around me have been raped of their belongs.
Very sad to say, not much more than what you are doing now will stop a determined crack head.
Motion detectors with lights and loud beeper focused on your boat would be your next option.
Next aggressive option would be to hook up a 5 acre electric fence shocker to your boat hull.
But that would be the extreme.
I am afraid I would hurt myself LAUGHING if I heard some screams coming from the boat in the middle of the night. :LMFAO:
and after thinking about it, and having seen the photos of your boat . . . .
one or two crack heads could do a quick grab and run with your boat, motor and trailer.
pull it out to the street and hook the safety chains to their bumper and be gone with it.
Not even have to address the padlock or any kind of lock - - - just let it hang loose with the chains
pull it a few blocks then deal with any locks you may have on it.
Remove all your markings - get new papers - and sell it - - - just as you described.
Maybe if you can dig a deep hole where your trailer axle is routinely parked.
pour in a couple of bags of concrete and put some heavy duty chain in it - - - then after it hardens,
you can at least lock the chain around the axle - - - a little more difficult for the crack head to deal with.
