So I had success with a small cruise/ferry last year. I had received what could only be called broken stl files. Overall it was a lovely design though had come from someone with no experience in the marine side of things. He had designed it though upon printing it realised it had a tendency of capsizing or splitting the back in the middle. So gave up on the whole thing. I saved the files and updated them all for a strong and more scale like hull.
My small 40cm version was great and even though a tiny ship the presence on the water was incredible.
I've decided I need a larger one for this year.
The difference though is this build isn't going to be a simple stick together, sand and paint then get on the water.
No this is going to be wood line the internal space then sand and coat in resin thus creating a smooth one piece hull. That'll add the extra ballast weight for me instead of having to add weights.
I'm then going to hand paint her to mimic the real version though will be altering a few parts of the paint design to my own taste.
For power she's going to be a triple motor. One speed 400 in the middle and 2 380 brushed on the outside that run through a Forge mixer for differential steering. There will also be a scale like rudder in the centre with the centre motor only being used for windy or rough days.
A bow thruster may be added though thats not for certain just yet.
Power will be supplied by twin 2s 1000mah lipo batteries along with 2 60amp esc and 1 40amp esc. Rudder will use a metal gear 9g servo.
There will also be a Rudder gyro onboard that will help her track easier and fight any tendency to slide out
The plan is to install working navigation lights that will operate off an electronic switch allowing on and off from the transmitter and spinning radar powered by a 3v motor. A Bluetooth speaker system for some music that combines a cruise ship horn and engine sounds.
Overall she should come in at around 1.1m long and an auw of 8kg
She continues to print as i type this so will add more photos as she continues to grow

Bit more progress in the last 48 hours. That's all her part's now printed. Next it's sanding along with filler time and then more sanding. Propulsion system is work in progress and awaiting 2 M2 shafts arriving for the outer motors. Rudder is printed and awaiting a servo arriving to link that though in two ways whether to have the rudder fixed as with the 2 outers i doubt there will be any issues with manoeuvring. She will have 5 blade props on the outers and 4 blade on the centre.
I've a bunch of nav lights and underwater illumination lights to wire up. Sea trials, I'm aiming for the 25th of March and hopefully cosmetically finished by mid April.

Hi DuncanP!
Wow she has beautiful lines. A lovely though simple hull. Upper structure a little tougher though not impossible. I'd happily try replicating her later in the year to around the 1 metre mark. I'm tied up with print orders for our club along with some of my own at the moment. Will be upgrading to 2 even bigger printers in August to help speedup the print rate. In the meantime i'll look into her more 😊 ▲

It looks as though she will be superb! Well done! I have looked in vain for a kit of the ship that took my father to war in the Middle East He sailed on RMS Aorangi so it would be nice to build a working model up to 1m in length. I haven't got the skills or the equipment to scratch build one. I just wondered if it would be possible to 3D print one. Here is some info about it:-
RMS AORANGI Launched in 1924 for the Union Steam Ship Company of New Zealand, and built by Fairfield Shipbuilding & Engineering Company, Glasgow (launched June 17, 1924). It was, at the time, the largest and fastest motor ship in the world. Its maiden voyage began on January 2, 1925, from Southampton to Vancouver via the Panama Canal. The vessel primarily served the "All Red Route" between Vancouver and Sydney, calling at Honolulu, Suva, Auckland, and Wellington. World War II Service: Requisitioned in 1941, the Aorangi served as a troop ship, transporting personnel to the Middle East and India. It famously evacuated women and children from Singapore in early 1942. During the D-Day invasion, it served as a depot ("mother") ship for tugs and auxiliary vessels, even providing medical services. More info on the internet!
