Hi mattstocks, what a great school. The windsurfer class association will be able to put together a board. (incl. a rig) It'll be second-hand , but it will be one with a swivelling centreboard, wouldn't inflict the good old drop-in type on you . (windsurfer one designs aren't the best learner boards available, but they still work out. Clubs in Qld, NSW, Tas, Vic have all used them. Actually, ct249 will tell you how a lot of Aus world champs learnt on them.
Then the schoolkids can progress on to other boards. blah, blah, you know all this )
Good luck. Great effort!! we'll send a PM when board organised. Cheers. windsurferOD
