Bourbon Orca is an anchor handling vessel based in Bergen.
The owners and builders wouldn't let me have a set of lines, so, I designed this myself on Delftship from photos available on the web.

The hull is plank on frame, driven by twin 900 size motors off 12v. She has an action twin esc and mixer which enables her to pivot on her own axis without the need to use the bowthruster

Svitzer tug Ayton Cross, built by Terry O'Rourke in 2006/2007. Mostly scratch built, on a Mobile Marine Models GRP hull.

She is powered by two car heater motors, with a Marx luder bow thruster. I have used an Action kit motor mixer, it works well.
