hi luffed,
i was looking for a hobie 14 or 16, (2nd most built boat in the world so must be doing lots of things right) but the area i'm in is pretty remote with high transportation rates and no trailers so when a nacra 17 came up for sale on the lake i sail at i bought that
i'm not sure of the weight of the TheMightyHobie18 but in many respects it seems more like a nacra than a traditional hobie
they are pretty heavy for solo sailing and righting and with their racing heritage there are a lot of adjustments to make while under sail so they can be pretty intimidating

BUT, if you keep at it, it will provide an exciting boat that you are unlikely to outgrow for a long time
