you guys should bring back the long range solar glider, it was such an interesting project

A transatlantic drone boat would be ridiculous but an absolutely incredible feat.

Heya! I have some experience with this sort of thing - the liquid level sensor corroded because of the DC voltage applied, which caused the corrosion. There are some techniques to mitigate this: you can either apply the voltage for a brief time for the measurement once every number of seconds to extend lifetime or apply alternating polarities with each measurement to reverse the electrochemical effects.
Either way, and I say this with the utmost respect, you need to up your waterproofing game. It sorta hurts to see so many of your projects scuttled by water ingress when your waterproofing amounts to just silicone, which sorta sucks for this. I recommend you check out waterproof cable glands with PE tubing to carry conductors and some more design considerations for things like acrylic windows like labyrinth seals and compression of silicone/other seals POST-cure.
Love your stuff, hate to see it fail due to the world's greatest chemical :)

What would be cool to see is a observation and data plane doing circles around the boat and sending the data to shore so you don't have to drive behind it!

Have you considered having the propellers reverse occasionally to try and clear the weed?  That's what we do on our narrowboats to avoid having to manually clear weed.  Maybe monitor voltage drop and program in a reverse phase when it needs?
Love your videos 🇬🇧😊

I’m always left speechless at just how creative and technically skilled this guy is. He’s always building the coolest stuff!

Use a capacitive water detector! Those can be encased in conformal coating and will still detect water. The resistive one you used is well known for not working long term

I wonder if a paddle wheel boat would solve the seaweed problem

I'd love to see you revisit solar autonomous planes and see how small you can make one.  Is it possible to go under 250g?

You should do a checklist for launching the boat so you never ever again forget the drain plug ^^

I look forward to your next autonomous ship mission

I hate to say it, but I think it's time for a new hull design after your next set of upgrades, incorporating everything that you have learned previously into making an efficient autonomous ship that won't be causing you any problems

Btw, ever thought about doing a community event?
Other people making autonomous ships and sailing along yours, competing for efficiency, range, who gets to the finish first, etc
I would be down and I'm sure others would be too

"In this episode, Daniel discovers the real value of 'Marine Grade'..."

You all mark my words, I will make a rc boat that will go across the UK








Thanks for the inspiration

I'm hesitant to get too close cuz it's an autonomous boat, I feel like i just need to let it do its thing.
You know, keep my distance.

You should talk to Plasma Channel, he's working on a Solid State drive for boats, with no moving parts, so it'd survive the seaweed.

nice bit of aquatic R&D there! Float switch for the bilge pump might work better?

I have to say. This is one of my favourite YouTube channels. I really enjoyed the last boat rides. Such a relaxed vibe! 10/10

I love the shots of the beautiful northwest scenery and wildlife almost as much as the project itself!

here before rctestflight creates a yacht in a couple of years, fully autonomous and solar-powered, it becomes known as the "drone hub" for all local pizza deliveries
