It's taken a long time to make, and there was probably more I wanted to do to it but really didn't want to wait any longer to release something for all to use. Instructions as follows:

1. Start in the water, obviously!
2. Use VTOL down to stow dinghy into the correct position.
3. To control the main craft use Throttle to go forward, Brake to reverse and Roll to steer.
4. For the dinghy challenge use activation group 1 to eject the dinghy into the sea. (Note the cockpit is in the dinghy, so don't lose sight of your main craft)
5. Use VTOL up to accelerate dinghy and Yaw to steer dinghy.
6. Line up the dinghy with the back end of the main craft and land that sucker!

Note: Best done while the main craft is at about 50% throttle and the dinghy at full.

The dingy is a little finicky in control because I had to minimise it's abilities when moving fast, hence the really poor control at low speeds, and it's sometimes ability to be difficult to manoeuvre.

Don't forget to keep an eye on your main craft whilst doing the challenge, and to repeat, just restart. There isn't a mechanism to push the craft back off again and restart (an extra feature I would have liked to have eventually added).

As always, have fun.
