choice dinghy/cat

seeking advice from the pros

I'm an occasional laser sailor on the belgian coast and looking for the next step. cant figure it out though. the belgian beach clubs are dominated completely by cats (hobies, darts, nacra). they're nice to sail, but so heavy and large (transport, logistics, etc). also, most often i'm alone, hence the convenience of the laser.  however, i occasionally sail with my father, a friend, and within a few years hopefully my son- which makes the laser too small. the laser vago appeals to me in principle but i havent seen it let alone sail it (there's a few about on the coast here).  skiffs you dont see at all here.  i'd be very grateful if people have some suggestions about the vago or other boats, or even a cat. criteria:

• easy, convenient boat (to rig, to transport, to store)
• can be sailed single or two persons
• can handle ocean (choppy conditions)
• not too extreme (65 year old or 10 year old need to cope)
• not boring either (eg trapeze, spinnaker)

many thanks
