Server 2 is a overload server for when server 1 is full or so busy people need to wait long to get in. Usually at night times, in weekends.
Second question: A shipwreck is a sunken ship, bottom of the ocean. It holds treasures, different kinds which will give different prices at the antique dealer in Kavala. You can get the treasures as followed:
1: Get a diving license
2: Get a diving suit + a backpack (dont forget that with suit I mean the whole package. Suit, rebreather, diving goggles. For sale at a diving shop, total 7.5k excl. license)
3: Get a Excavator at the market
4: When you are alone: Go with a boat to the wreck, dive down to it (night-vision advised as it is dark at the bottom sometimes, at great depths). Press Y, select excavator, use, get treasures. Put them in boat till its full and go sell.
When you have more guys and a helicopter: Fly toward the shipwreck on the map. Lower helicopter to below 6 meters, in autohover mode. Make sure diver is NOT in co-pilot seat. Make diver jump out, will not be hurt. Swim down, get treasures as stated above, and when filed put in heli till full. Then sell.
And one more thing. My grandpa always used to say;
"The only dumb question, is the question that isn't asked."
