Some objects not rendering in Flamingo NXT from Rhino 5 model

[m.j.harris09]

I have 5 boats from different models which i have combined into one model. When i go to render the combined model only two of the boats appear. Each boat has previously been successfully rendered in their own separate model.

What is happening and how do i get all the boats to appear in the render?

Here is an image of the model with 5 boats in it and the rendered image with only 2 boats in it.

Clipping plane?

I checked for clipping planes and there were none. A clipping plane would also show up in the shaded view in Rhino.
