Transporting multiple kayaks and bikes

[Flatlander13]

Alright, I've got 6 kids who all have bikes and what will be a growing fleet of 8-12' sit on kayaks. What have you guys done or seen done to haul both together? I was thinking of some sort of modified boat/PWC trailer, but know there have been some done on the harbor freight/northern tool platform. Ideas and pics would be helpful.
Thanks

I use a small Jon boat type trailer.
