Chris..Well... I love the stability, durability and performance under power and rowing of my RIB. (Caribe)
The downside is that they are relatively heavy compared to pure inflatables but the stability issue with young kids may be an offsetting factor for you. If weight is an issue for you, I would recommend something with a wood or aluminum insert floor for added rigidity and puncture resistance over an air floor model....but the air floor units perform much better under power and when compared to standard floor inflatables. I am not impressed with any hard dinghy for family use or towing unless rigging sails and having a fun boat for the kids is important to you.
