Are there 12V motion detectors that can be coupled to very bright spot
lights? Set the detector to look at the companion way and the spots to
illuminate the cockpit.

I went to my boat today to tie up for any surge from Katrina and found
for the second time that kids have been aboard smoking pot. They do
not steal anything or do any damage but they do leave butts and ashes.
This time one left a T-shirt which could be used to ID them if I was
really interested. The first time I think they got aboard by me
leaving the combo lock unlocked (you have to spin the tumblers and I
forget). This time I think they actually removed the hasp but
carefully replaced the screws when they left. Security at the dock is
minimal and would be difficult to enforce. I do not want to get them
in trouble for the pot smoking and do not really want to get them in
trouble for using my boat while doing no damage. However, they could
get hurt being stoned and stupid so I want them to never come back. I
left two notes for them telling to leave my boat but I do not think
they will see them because they do not turn on any lights. I'll
replace the lock and hasp tomorrow but wonder if anyone else has any
suggestions for a way to warn them without hurting them.
