I have spent a lot of time looking at very small light dingy options as I am planning an extended trip into croc country and don't wish to tow a dingy and my yacht is too small to carry one on davits. My inflatable 2.3m island fits perfectly on my foredeck and one person cranes on and off with my spinnaker pole and its topping lift back to a sheet winch but it's not good around crocs as too small and chewable and also too slow for some of the longer dingy trips in The Kimberley's. Also whilst never having a problem previously apparently oyster covered and sharp rocks are a problem up there.
In response I have purchased a 3.28m folding Portaboat secondhand which sits in my stanchion mounted SUP carrier as we won't be taking those up to The Kimberley's. It is awkward to construct on the foredeck and launch and retrieve from there with the same spinnaker pole arrangement. Our exceptionally shallow draft yacht will hopefully limit the need to use it to only a few occasions.
The inflatable will come with us as well as inflated in the foredeck it both provides shade cover over much of the cabin and is quick light and easy to use if out at offshore islands in clear water. It's also our cheap life raft alternative and it pays to have backups for everything for very extended very remote cruises. In line with this we will be carrying two dingy combined yacht auxiliary outboards being a torqeedo 1103 and a Yamaha 6hp 4 stroke both of which can also power the yacht in light or no wind conditions saving the fuel otherwise used by our monster outboard.

Potaboat shown here with only the stretcher plank with the three seats yet to be pinned in. It is heavier than the inflatable but not by that much still being under 40kgs and would make a great alternative if easier to construct on a smallish foredeck.

PS It's amazing that the torqeedo 1103 can push our around 3 ton yacht at 3 knots on half throttle for about 1.5 hours and also get it to over 4 knots on full throttle which however drains the battery in around half an hour.
