| Rim thrusters.
These rim thrusters are already in a size and power for integration into mainstream yachting circles. Canyon ROV utilise these on their Schilling Quest electric work class ROV. Alstrom bankrolled the development with their eye on future markets. There were initial teething issues, mainly to do with material/lubrication of the ring bearing and adjacent surfaces, and these have been resolved. Cost is the prohibiting factor at present for the general public. Now that the idea is out there and proven, development by competitors is sure to reduce the cost to a more attainable level.
