There has been some discussion at our sailing club about using an aerial drone to make videos of the racing. It sounds like an excellent idea but some of the more pessimistic members have pointed out that if you lose control of the drone it will crash into the lake and never been seen again.
At last, there is an answer to this problem.
The CRACUNS (pronounced krakens.)
CRACUNS stands for Corrosion Resistant Aerial Covert Unmanned Nautical System.
CRACUNS is a drone that is designed to work in the air and underwater. So it can lurk and move around underwater for a while until the operator decides to give it the command to rise from the water and up into the air where it can perform whatever mission you desire, such as making a video of the Flying Scot start or taking out the chairman of the protest committee.
I can't wait to see the looks on the faces of the sailors in the Sunfish fleet when a CRACUNS rises from the water in front of their fleet just after the start of a race!
