Own modification with Alu profile to get tether pull in midpoint of ROV.That makes the ROV yaw/turn less when there is drag in the tether.Also provide a more firm lifting point when getting in/out of water.In other words: poor mans LARS system
I like your design. It looks very robust. I see your bar is mounted high at the rear of the ROV. Had you experimented whether it was better there, than center, or lower?
Good choice with the locking clip. don't want to get it caught.
I have not tested with lower mounting.I want to have tether away from bottom, and away from thrusters.Extra tether fixing Points are for taking stress from the low budget tether Quick disconnect..
