Here is a very short video of one of my Springers going past our floating dock and under the access footbridge: https://www.youtube.com/watch?v=dIe8TU6kiEY The video was recorded on Nov. 6, 2022 at Lake Seminole Park, Seminole, Florida, USA. Weather was clear, low wind, and about 85F.
This Springer is based on a real "truckable" push boat based on several photos that were measured. The pilot house goes up and down like the real one, using a cog belt drive from an old HP inkjet printer.
We were going to do a "push off" but the other Springer had a battery issue☹️. Perhaps next time...
