Converting your quotes to :

sl16 13.374 Euro's (=21100chf)
hobie max race 15.275 Euro's (=24100chf)
hobie fxone 15.402 Euro's (=24300chf)
hobie tiger 15.592 Euro's (=24600chf)

These all sound alot more expensive then the quotes I hear for the Nacra 500 here locally, I remember the bare Nacra 500 (no spi) to be 10.500 Euro's. Maybe Macca can give the most current quotes for those boats. Compared to the F16's (= max 14.500 Euro's) the Hobie max sport c.q. Le Race version quotes are just ridiculous.

For the use you propose I would again advice the Nacra 500, it seems the best solution and the most cheap one as well. The difference in fitting out between the 500 and SL16 is negligiable although the 500 is rating faster. I think the decision between 500 and SL16 is a no brainer, get the 500. It will be alot more easy to on later. The 500's are quite in demand overhere.
