Wim Kruiswijk of the Netherlands has been finding messages in bottles that have washed ashore at the Zandvoort coast since 1983. He now has 1200 of them in his collection, which is roughly 35 bottles a year! While this short documentary doesn’t go into it, it seems that the coast of Zandvoort is known for its beach-combing discoveries. In fact, the local museum has a display of washed-up finds, including some message in bottles.
