What happens if you ram the other boat?
These ones I've tested with are big and slow, so the only result I've seen is they easily become stuck.
Can you walk on the boat without mount points?
Yes, except the boat won't be able to move.
The way these things work (im guessing) is they force the vehicle to snap to the environment water level, while acting like magic carpets that cant roll. First done by stratofortress, but his have been broken for a while.
Would love to see these released!
Close, the vehicles are planes that (mostly) can't roll or fly. They also float on any water, no snapping done.
Here's what I modified to make 'em work
Lowered density to ~0.15 for buoyancy
Adjusted mass to prevent bobbing
Set wheel spring length to 0 to prevent land control
Set lift to 1 to allow water control while preventing the boat from taking flight
Adjusted forwardThrust and reverseThrust to set its speed
Set verticalSurfaceForce to 100 and horizontal to 0 - prevents lift (?)
rollForce and pitchForce to 0 to prevent awkward tipping
yawForce set in hundreds of thousands or millions - for turning
If it's somehow midair, it'll glide a little and can still turn
If they're big and slow, they'll get permanently stuck very easily
At any time they touch water, the whole vehicle is treated as submerged, which can be interesting..

The boats themselves are stratofortress',
here they are.
