Ok, I have a very interesting project for you to work on now. I have more projects as well but this one is ready to go now. Let me know if this is something you'd be interested in working on.
Are you familiar with swath boats? We are building a swath (our test model). This is a 1/8 scale model that we 3D printed and tested in our pool.
We have a full scale size fiberglass model that is about 50% complete but currently on hold.
We have a very futuristic/fancy design for the top passenger section (below). The part that goes on top is mostly just for show and isn't so important in terms of the engineering that needs to be done. This area only has a conceptual design ready at this point and can be changed/modified as needed.
My fiberglass expert is going to start investigating the feasibility of making the passenger section this week.
From you, I would love to see what you could do on the engineering side for the base (under the water section) to see what kind of buoyancy we would have and how much weight we could support on the top passenger section above the waterline. We would ideally like to carry 2-4 people + some baggage. We are using electric thrusters so we will need space for enough lithium batteries to make 20-40 mile+ trips. Feedback and suggestions on how to modify the swath base to improve buoyancy, stability, maneoverability, etc are very welcome.
We are using 2 PR212 motors from here: https://static1.squarespace.com/static/5d66b3fa2b391600011db85d/t/5e25fdc8a29f9d6b4e4bd927/1579548110947/Product+specifications+Propulsion+motor+168.pdf). I'm also interested in your opinion on what kind of turn characteristics a vessel like this would have?
