Hi @mateov,
This isn’t something I’ve personally tried, but the idea seems reasonably straightforward. My main concerns would be
- avoiding cutting the tether with the boat propeller
- may need to route the tether via the side or bottom of the boat
- likely need to avoid sharp turns
- need to be careful of excess tether slack when first starting to move the boat
- avoiding high tether strain
- may need an additional cord to take the load
- ROV pitch angle
- the boat is above, so the mounting/pulling point would need to be from somewhere on the top of the ROV, to avoid undesired pitching
- video stability
- depending on how smoothly and fast the boat is moving, and whether any oscillations are induced in the ROV, there may be problems with capturing usable images/footage
- may help to add elements that improve the hydrodynamic flow, to reduce drag and oscillations
Beyond that, this post is likely of interest, and you may want to look through some of the other posts in a forum search for ‘tow’
