These are two boats that were used on japanese ships in WW2. Both are 12m.
The models are meant for 3D printing and are therefore quite simple without much detail. The size of the models when printed will be: length: 7.9 cm width: 2.1 cm height: 1.84 cm
I created these for a 1/150 model of the Aircraft Carrier Zuikaku. (I've also printed the row boat as a 9m and 6m boat by simply resizing them)
