I've flown my
Mini 2 from our boat several dozen times but I only got it the day before we set off on our last two week cruise. I use one of those pop out round helipad things which I have managed to wedge down in the cockpit under the level of the coamings. So far I've managed to land it on target but if the landing went pear shaped I might lose some props but hopefully the M2 wouldnt go overboard.
I have to admit though that all my flights have been when we have been at anchor so you have my total respect for flying whilst sailing as there are so many potential hazards on a yacht because of all the shrouds and rigging. Coincidentally I watched a video today about various hand launching/landing techniques and the guy said one of the most important aspects is to learn to have confidence in the drone. I only started to feel that towards the end of our holiday but I can see now it would be feasible to fly the M2 at the boats speed and then when everything seems settled slowly move her sideways close enough to grab hold. I can see you would need something like you have made or maybe those extension skid type things I have seen advertised.
The problem I have is that our boat is over 300 miles north of us and we only get to have three two week cruises a year so I have a long time to wait before getting a chance to try anything. There is one good point though and that is I will be hugely more experienced next time we sail and hopefully not have my heart in my mouth for every landing.
I would love to hear how you get on and also see some of your footage possibly .....
