hag Ahoi is Hamburg's wonderful cosy but energy bursting Collegiate Shag festival. We're happy to welcome you back at the 'Elbe waterkant' this summer. We have three levels of collegiate shag workshops from intermediate to advanced with 6 hours of classes, three inspiring teacher couples, one half pass option (Saturday classes), 2 evening parties with live bands, a swinging boat trip, an outside teadance on Sunday, and a lot of fun!
