For Crazy Fish I purchased an Achilles LSI 335 - 11' dinghy with inflatable floor weighing 91 lbs 3 years ago.
It replaced a 10' foot Avon Roll Up with a plastic floor that weighed about 20lbs more.
A 2 stroke 15 HP Mercury outboard drives it. Purchased the outboard used off Ebay out of Wisconsin (limited fresh water use only).
It may be a bit larger then some might desire but I use it a lot for scuba diving and make some longer runs in it to get to decent sites. Will easily plane with 2 divers and their gear.
The inflatable floor made of hypalon has held up well. It can be easily removed and replaced if needed. This summer during a 2 week cruise we put some small holes into it which I believe came from the West Highland Terrier jumping into the dinghy from the big boat and driving the nails from her rear feet into floor. Patched the holes and covered the floor with a piece of indoor/outdoor carpet. Before heading off crusing I will likely buy another floor.
Otherwise the boat has held up well, motors well and with the dinghy wheels is easy to beach.
When underway the boat normally sits folded up in front of the mast between the mast pulpits. To inflate its un-rolled and laided across the the lifelines.
