Hello all

I have played around with fixed-wing drones before but am new to boats. I am looking to build a simple boat for the purpose of inspecting a heavily timbered section of river that it is hard to get a manned boat into and am looking for some suggestions on where to start. I don't need a sounder or overly accurate GPS (but both would be good to have). I would really like a high-resolution camera in a dome housing or similar that I could control and take photos with. I would also like a water jet motor not a propellor as this can get snagged on timber, and in weed ect

Any suggestions would be welcome

Cheers
