Boats are easily the worse and the most risky place to use dynamic home point, you have to realise a boat is constantly moving and will require you to set DH almost every 5 seconds even if you manage to do this, let’s say you hit RTH and your drone starts it’s run to DH and while flying back you lose signal , all the time your drone is flying back your boat is moving so homepoint is now continually moving even if your anchored, so let’s say you now lose radio signal , your craft will continue its return to DH which will almost certainly have moved, as it lands you have a couple of choices try guiding boat under landing drone or jump into water and try hand catching.
Using drone from a boat you always be within VLOS in fact well in VLOS you set loss of signal to hover you then use boat to get to the drone you should then by getting closer to the drone be able to recover signal and manually land , if you don’t regain signal you can just wait under drone until it lands.
first of all, i suggestion to anyone flying with DH, not to click RTH.. manually take over when its time to land for any reason..
if its active tracking you, which is the most likely use case, it should always be within VLOS anyway, kinda has to be to continue to track you on active track. once you hear your low battery alarm, you should then pick the controller back up and manually bring it in to land on your location. assuming most people leave low battery at 30% (default) that gives you several minutes once alarm goes off to sort things out.. having used active track with DH before while boating (mavic pro). i never had issues, i mean maybe if very windy or going too fast. but assuming that active keeping up and following you not letting it get too far, once battery alarm goes off, you make sure you bring it in, landing on boat or i always hand caught it and pulled down on stick to have it spin down..
if signal is lost it should always default to hovering in DH mode... not landing. but in theory if using DH correctly, shouldn't suffer signal loss or they should be very minimal if it happens.. because in DH should following you, not something else may get beyond range and battery..
the reason i suggest adding GPS follow into it as a sorta hybrid form to it is to verify what its following is actually in possession of the controller thus able update the homepoint and stream in new homepoints... if it sees its not following GPS somewhat it can turn off DH and revert back to takeoff HP say GPS data from smart device stops for period of time...or sees your smart device is back on the shore, it can turn off DH.. but if GPS data from smart device kicks back in and is in agreement with aircraft then it start updating again.
