Challenge 4 - Wheelchair Dinghy

[SOLVED] When marina cannot accommodate, or to simply broaden operational possibilities as for exploration, be able to safely anchor out, launch a very stable wheelchair-friendly 'dinghy', and allow all passengers including wheelchair users to go ashore by transitioning from larger vessel to the 'dingy' and back. Minimum 800 pound capacity, 1400+ lb capacity highly preferred, probably electric powered for reliability, and not to exceed 8'x14' with 6-7' x 10-12' desirable if stability can be achieved. 

       Solution: EZ-Dock or Connect-a-Dock
