I made the hatch covers and holds for the ship model. This model will show the hatches in a closed position as I plan to show it loaded with wind mill parts.
I built the holds as a separate assembly since it is essentially a shallow box. I cut the parts with the laser using 1/8th and 1/16th inch acrylic.
I used photos of the prototype MV Jummetor as a guide for the hatch design including the oval shaped reinforcement plates. I think they add a nice bit of visual clutter to the simple hatch design.
This shot shows a 3 bay covered hopper next to the ship for a size comparison. Also, there is a 20 ft container on the rear of the hold.
