This is my Power Functions Trimaran MOC. I was inspired by Jeremy McCreary just for the name of the boat, but I had originally started building PF R/C boats even before I joined MOCpages.
About this creation

Here is the stern & transom view of the boat. The main hulls are from the 2017 City Police Boat and the two sponsons are from the 2017 Fishing Boat. The boat is propelled by a single scratch-built outboard motor with a PF L motor driving a single 2-blade 9mm propeller. If you look closely, you could probably see green fluid leaking out of the motor. Don't worry about that, It's only Corrosion-X, which I use in almost all marine motor applications. The boat steers by using a friction-set rudder.

Overhead view of the motor and rudder. The rudder is very simple but at a cost it's somewhat weak. It stays in place by using the friction between the 3 gears and the plate against the main bearing. It works well and believe it or not, the studs don't add any thrust drag.

Overhead view of the entire boat. As you can see, its power comes from a large AA PF battery box, and it sits in place by using two brackets. A windshield adds looks. Behind the main wire is a plate which prevents the motor wire from going into the propeller if it suddenly became loose.

Keel and bottom view of the boat. The three hulls make the boat very stable. One thing I don't like about the main hull is that it doesn't include a motor mount, but that means it has less drag and air pockets at the bottom. You can also see the outboard gearing and propeller shaft.

Quoting Builder Allan Hello Angelo :-) I'm sorry to hear about your uncle's cat, that's really sad news. I never do use poison for that very reason, and fortunately the most common way to excersise pest control around here seems to be traps. At least, there are plenty of cats in my neighbourhood and none have ever lost their lives to poisoning. About my own new cat: Yeah i have not had a photo shoot yet since i got him, so it shall be exciting to see if he is as curious - or more - as my old cat. Unfortunately he was already used to running outdoors, so i can't keep him indoors. All i can do is hope he doesn't meet the same fate as my old cat. According to most veterinaries keeping an outdoor cat in would impact the cat in a negative way making them agressive and restless. Also, i actually don't have enough room for a cat to feel comfortable. I would have preferred my next cat to be an indoor cat though, and if this one hadn't turned up when he did i would have waited with getting a new cat until i had moved from where i live now. Thanks for your concern though, nice of you to show you care :-)
Thanks a lot, Allan. Yup, I'm not to sure if my uncle's cat was an indoor or outdoor cat, most likely an outdoor cat. Good luck on your new cat!

Quoting Builder Allan Nice! I bet it wasn't easy figuring a solution that would prevent the PF motor and batteries from getting wet and still drive the screw :-)
Thanks Allan! Actually, the electronics never get wet. The battery box is far above the water line and in the video you can see the motor near the water, but I had sprayed Corrosion-X inside of it to prevent rust. Those L motors have been on plenty of boats in the past!
