Good luck
I believe the Seagull was used by the Brits on small boats during WWII, and hasn't been improved upon since. I was always intrigued by its two speeds (zoom and stop), which required killing the engine at a certain point so as to glide into the dock. The other key feature was reverse, which entailed literally turning the motor on its access. The thing is a danger to women and children in terms of heat burns, but otherwise an adventure all unto itself.
