I’m glad we’re getting more long range missions, the banana boat video where it goes on a long trip is still one of my favorite videos

Hi I'm from Germany and I'm in a model boat club and as a last resort against water in the boat we use a so-called bilge pump with a float switch that pumps the water off automatically when it reaches a certain height in the hull You could also use a shaft seal ring to seal the stern tube to the shaft.

Hope my suggestions are helpful😅

With a slightly larger vessel you could add solar panels and Starlink for super long-range offshore missions.

You should add speaker and microphone to the boat so you can communicate with people.

Everyday we get closer to eventually getting a flying boat

That’s a fine lathe you got there. Thanks for showing both the successes and failures as always!

You should put a speaker on it so that if anyone does approach it, you can just tell them, "Hey, this is a test of a top secret DARPA project. Back away or the FBI will arrest you." Lol

The props are for a surface vessel (design to stay half submerged and to spray a mix of water and air). To improve the speed, efficiency and tug force you should use a different props, a full submerged one, without the flat part on the blade. Beautiful video as always!

Nothing worse than a leaky shaft

Captian here. REAL Actual Captain.  The one in my 40ft trimaran is just a big pencil lead. hint hint
Okay so attach a pencil led wider than the shaft facing towards the keel with a set screw.
Then a boot sealed to the hull and sealed to the other side of the pencil lead. adjust the pressure
Of the two pencil leds touching each other with the set screw on the shaft placed pencil lead.
The graphene-to-graphene gap is less than a water molecule wide. So it does not leak and lasts forever.
Mine is 15 years old and it's time I change the boot as it looks someing like a toilet plunger yet the resistance
is not what it used to be thats the only reason why it needs changing. Higher horse power does require active cooling
of the big pencil leads. I thought if I say pencil leads it would be easier to understand than graphite puck with a hole in the middle.

Sorry to see you go through this over and over. If you need details I am sure I can get you some.
Q: You may have some questions like how do you make a gap the fine?
A: You dont you just run it and it will stop leaking by itself.
Example: My boat was sitting in the ocean for a long time before I bought it and the boot is loose so salt water started too drip and for deposits in the seal making it not work as well. I literally climbed down there and sanded it while taking on water because the boot was pushed back for a moment. Very scary. Anyway after sanding it
then running the motor for an hour it was good agian.

Dude you're fulfilling every nerd's dream of controlling an RC vehicle from a Coffee shop, The fact that its a boat makes it even better. Thank you man.

Nobody will ever see this but, I just want to thank you for existing, I get sick a lot and whenever I do, I know that I can always just sit back and watch some good old rctestflight. Thanks you.

Your projects just keep getting more impressive.  I'm a pretty big R/C nerd but you've evolved to the point that I don't understand half of the tech you're using now.  Keep up the great work.

the fleshlight joke was golden. most people will miss it

Crammed a lot of sponsorships in 1 video lol. Most of them worked pretty well since they went with the flow of the video though.

Have you ever thought about leaving a small bilge pump in the hulls?

Stuffing box... wow... that is so old school.  Modern boats use a dripless seal.

Dude, this is just truly the most cool thing you have ever done!! AND YOU HAVE DONE SOME INSANE STUFF!! Sooooo Cool!
