Hi Phil, Thank you for the DW information, it's one sub design I'm fascinated by. It has a cuteness factor, sorta like being the Volkswagen Bug of the sub world. Perhaps some day they will make a Herby the Love Sub movie with one. ;)' How many DW's have you and your team produced over the years? They seem to be gaining more and more popularity for a very large variety of research projects. Cheers to you and your teams successes. Would you ever seriously consider using a smaller version of the Schilling Ring Thruster if they came out with one? Since Schilling is no longer merged with Sub Atlantic I was hoping they would start to produce the ring thrusters again in a number of different sizes, and for a number of different applications. There extra efficiency is mostly wasted when used for tethered WROV applications. Were on a sub, that extra energy savings would be much more useful. http://www.youtube.com/watch?v=No0pzwOLabk I don't know if the special magnetic bearings will interfere with other electronics in the DW, but since there are a lot of electronic system on the Quest WROV's that use the Schilling ring thrusters, I would expect there is a good chance of no interference.
