View Full Version : Boat Alarm

Most of the time when we return from skiing we stop for dinner with our trailered boats. We usually have to park were we cannot see our boats, but in well lit and open parking lots. There is a lot of gear in my boat and I don’t like having to move it into the van and back out of the van just for a 30 minute dinner. So I thought it would be cool to have an alarm that would page me so I could run out of the store/restaurant and chase them away.
My requirements were; pager, radar type proximity sensor with two stages, one warns you that you are too close, the other sets off the full alarm. While I was at it, I thought the voice warnings would be cool instead of chirps and honks. :rolleyes:

First step was a paging alarm system with a radar sensor. I bought the Astra 777. It was one of the cheapest paging systems and radar sensor combos that I could find. The radar sensor was a piece of crap and I replaced it with an Audiovox model AS-23. Tests in the driveway were satisfactory on the two stage.

If I was going to go through the trouble of adding a voice, I figured why not a fully programmable one. Bought the DEI 516L Recordable Voice Alarm add-on module that has 5 second programmable voice warnings. My first stage warning says “Move away from the boat, surveillance system activated”. The second stage says “intruder alert, surveillance system recording.”

I also put some cheesy LED arrays that scan back and forth, ala Knight Rider. I slap them onto the windshield brace, held on by Velcro. I have them set up to turn on when the system is armed.

I also put a relay on the tower light’s dashboard switch so that they can be turned on either by hand or a stage one alarm.

So last week we stopped for dinner, parked our cars/boats in the parking lot but just out of sight from where we were eating. Half way through dinner the pager went off. I ran outside and sure enough there was a guy next to my boat stealing





…….the cardboard boxes out of the dumpster next to my boat. :uglyhamme

After using it about a dozen times, I can report 2 false alarms, one dumpster diver caught and successfully “catching” my kids testing it four times. :toast:

Wow! Your alarm system not only gives you peace of mind, but also provides a great story! Thanks for the chuckle tonight.

Dan you kill me. Maybe we should start calling you MacGyver. Why not add some passive infrared sensors?

Infrared has too much range and flakey sensitivity settings. The better "radar" proximity sensors have more precise short range performance. I have it dialed in pretty well now. If you get within 2 feet of the side of the boat the first stage warning goes off. I you wave a hand around inside the boat the second stage will go off.

I try to make sure I am never more than 12 feet away from a roll of duct tape or a swiss army knife. :D

Nah-ahhh...You just don't have the big bucks and security clearance to see the good stuff my friend. ;) I could tell ya' about it but than I'd have to kill ya. :D

Also the infrared is a beam sensor/transmitter using line of sight. The "radar" sensor is more omni-directional and goes through things. Makes the "radar" sensor easier to install on a boat with only one sensor.

You're right, it's all a trade-off for the Benjamins. But then why not just put a Phalanx Gattling gun on my tower? They are old enough that I should be able to get one cheap. 8p

btw I would bet that my security clearances get me into places you have never heard of. Let's just say I know how to spell Reconnaissance and Surveillance without a dictionary ;) .

Well I'll say you would amazed with what they can do with PIR. Some of the ways they are utlizing it in certain types of ordnance would blow you away. Also, depending on the censor you can get 360 degree coverage and vary sensitivity settings.

Of course like anything their is a way to beat it. If you actually move slow enough (I mean like inches per 10 seconds) you can walk up on PIR. Try it next time you go to the grocery store. See how close you can get. Don't worry about all the people staring at you.

Dan--Just put a few of these around your boat. They have a directional shape charge so the blast and frag shouldn't cause any damage to the 209. ;)

Yes I have thought about it, if the voice alarm doesn't scare them off. I figure it wouldn't be too easy to run and carry a water ski or wakeboard, so I think they would drop it as soon as I yelled at them. I would never physically confront anyone, it's not worth it. But I do have some experience and I have been told I am more than a little intimidating. Plus I have a boat crew to back me up (if they can put down their cheeseburgers) :purplaugh

If there's a stage 3 alert, please get a woman with a nice voice to say "laser armed" or "self destruct sequence initiated" with a countdown, of course.

On a more serious note,

Have you guys ever wondered why Mastercraft doesn't offer lockable ski lockers or storage compartments?

Anybody ever customized their boat and installed a lock on the ski locker or the storage compartments?

Dan C. you and I may have traversed some of the same terrain, albeit many years apart.

I can spell those words also without looking them up.

Here's to ya.
