 Emergency things that you could do, a minor repair on the water if you needed to, an extra prop is not a bad idea in case you hit something and knock a blade off a prop. It's nice to have an extra prop that you can put on there in an emergency, just like having a spare tire for your trailer. The other thing is to make sure your trailer is ready to travel. Are your tires good? Are your wheel bearings good? You always see somebody on a holiday weekend alongside the road with one wheel off their trailer because they lost it in the ditch and lost the bearings on the trailer. We back these trailers in the water all the time.
