This is my new boat. After the success of my USS Garrison, I decided to build a large-scale fishing boat with lots of functions. AC1+VTOL Up opens the cabin door. AC2+ VTOL Down 3/4 lowers the fishing rods. Up 100% folds them away for when you're going home for the day. AC3+VTOL up almost to the top, just barely under the line, prepares the radar. This MUST be done before you throttle up. Be sure to deactivate AC3 before you engage any other functions. AC4 fires a torpedo. I really love this boat and I hope you do, too. If you can figure out cockpit mode, that would be great. I made a fairly nice cockpit for it, but it won't go int cockpit mode for some reason. Successors are quite welcome as long as you change something. Use Yaw to steer. Enjoy!

Edit: Use roll to activate the whistle and put the landing gear up after you set the radar. Put it back down again before firing the torpedo. This is the targeting system! Also, thanks to WalrusAircraft for the propeller.
