Security systems to prevent unwanted boarders.

Can you hard hot them using the house battery instead, or just use the rechargeable battery like Eneloop ?

I prefer motion than mat, becasue I want to sound the alarm and flashing light before they board.

Loud dog, short shotgun, being there all the time, and hanging out with fancier boats than yours. These are a few of the best security options around.

As for the tack mat, make a bunch of small tack tiles out of lead. Make the tacks by straightening fishing hooks and embedding them (barbs facing different ways) in the lead. Just a couple of good long hooks per tile, for maximum wiggling and pain.

Oh yeah. Don't ever step on one yourself. :-D

The comapnionway screen or bars are great as they allow you to rest without worry, be sure to rig a dead bolt on the inside of your sliding companionway hatch..
On the catamaran, with the easy boading steps on the stern, we used a $10 "trip alarm" from radio shack in the cockpit. It's a little plastic box about the size of a cigarette pack. you attach a fishing line to a little tab on the box and tie it on the opposite side of the cockpit/boat from where the box is tied. When someone trips on the line it makes a very loud alarm. The nice thing is , you wont have any false alarms as you might with motion sensors etc.

I use strain detectors epoxied under the deck and under the swimstep. They are on the dry side of the boat so they last and they don't give false alarms. The weight of someone stepping on the deck area above them sends off the alarm.

So, kinda like shooting Clay Pigeons - press the button and the target appears .

Be useful when the decks get soggy too.!!!

That is what I found too.

Set to a camera it recorded, well.............everything.

And soon had no more memory.

And also each time someone just paddles by to say HI!

I always have a ziplock bag full of cash in plain view if someone were to enter.

The cash is soaked in dimethyl mercury

Here's some hints on what somebody else already does for security. Scroll down the main page and take what ideas seem good to you.

We met these nice folks during our meanderings. Their dinghy motor really DOES look like crap. Operative word: look.

Yes. But remember you have voltage differences. 2 x DD batteries ain't 12 volts. Mind you it could make the siren louder!

What kind of boarding are you trying to prevent....? naked windboarders?

You need to up grade! This one only takes (1) 9v battery and lasts a long time, unless the alarm goes off. Plus, I pull the battery unless it's being used.

ISafe T Alert RV Intruder Alarm

The down fall is it is visible and could be smashed if a tool were handy and one were expecting it.

We have two 100 lb. Chesapeake Bay Retrievers. The breed is very territorial, and was bred specifically to keep intruders off of their owner's boat in the Chesapeake Bay. So, protecting their boat is genetically ingrained!

The oldest one has been professionally trained by a K-9 officer, and the younger is quite happily follows his lead.

I feel bad for any person stepping onboard our boat without the proper authorization!

Cheers,
Octopussy

The best security is to sail where you don't worry about boarders, but this company makes some interesting products.
