Sorry to judge but... "when we got up in the morning all electronics and back packs were gone"

That could sound like you made yourself an attractive juicy target. Nothing says bait like a lot of bright electronics or a parade of backpacks down the dock then left laying out in the open areas of the salon. The next mistake many make is wallets left laying on the nav station. Consider this? When you park the car at home do you leave the backpack or purse on the front seat?

In any zip code it only takes a single digit few to create a "crime problem". That usually starts with someone making the crime really easy even lucrative to a person who has nothing. In my opinion, island crime across the globe starts is someone observing something that looks lucrative. Then we they think everyone is gone or everyone is asleep the "sneak thief" goes very quietly looking for it.

Again the only time we have been guilty of crime on any island is Antigua were we left everything out and every door open. 28 guys sailing a really big boat all sleeping together and we got robbed.
