Dangerous but fun: 400 boats sailing rock slalom in Sweden

During the very popular swedish race Tjoern Runt a lot of boats damaged their keels or their hull structure – every year again. See the ASSO 99 sailing through the rocks – with speeds over 14 knots and without kissing swedish granite.
Thousands of spectators were sitting near the fairways on the islands. Sailing Tjörn Runt is really big fun and very popular!
