East Coast, so pretty far away, but still applies. My boat was broken into, they came from the water, threw the dinghy (10'-6 Caribe with a 15 HP motor) off the boat deck and used it to cart away all the stuff they ripped out. Broke doors, broke an RL80-C and RN300 (both of little value even then in 2014!) out of the dash, lots of cosmetic damage, costly to repair. They neglected to put the plug in the dinghy, and it swamped with all the stuff in it about 200 yds away from the marina near shore. They had it chained and securely locked to a neighbor's dock intending to retrieve it later. Now these were some dumbass crooks. Boat neighbor was asleep through it all not 30 ft away. He's hearing impaired (really) never heard a thing. They came by water. Cops found the stuff during a domestic call a couple weeks later, I got it all back, but worthless. Ended up with a $27K claim because some druggies thought old Raymarine gear would be worth a lot of money. Crooks were caught, indicted, convicted. Claim was a fight every step. Break in was in March, claim paid in September, non-renew notice 2 weeks after the check was received. Nice. May be why Falvey is no longer in the marine business.
Thefts are really upsetting, lots of aggravation and a real pain to return whole. I agree, a live person with a bright light is probably the best deterrent. Like shining a flashlight on cockroaches, they scatter. Personally, I'd neuter.
