Weekend Salvage Dive...
For the last few years, Kowaliga Marina has a concert, with the stage facing the water, and you have to be in the water or on a boat to watch the concert.
The stage is set up on the beach, swimming areas are roped off and boats are tied up in an ampitheatre design. Every year, we pick up thousands of dollars in: sunglasses, cameras, jewlery, money, wallets, clothes, hats, unopened drinks(nothing like bringing a cold one up with you after a nice dive), masks, fins, snorkels etc.
This one is best done by spending the night on a boat the day before the concert, have a good time with the locals and visitors, enjoy the concert, and either dive, at night, a few hours after the concert, or be one of the first ones in the morning after. Last year, we pulled up in the boat at 7 am, by 8 am, 3 dive boats were in the water, about 6 people were coming in from shore and by 9 am there were about 20 divers in the water.
Most stuff is found in less than 20 ft of water by fanning out, but the best stuff is found out to about 40 ft where their teenager couldn't snorkel down to get it.
