There is a new much better SAR cruiser that I created check it out:

I made a version with modular engines that can reach over 80KM/H for very long distances before overheating. 60 KM/H is stable "forever". Check it out... The instructions are not yet updated.

There is or should be a timer for 10 seconds at the door (charge) and in bad weather it is better to use the upper door. My problem is I forget to close the doors.
I need to work on the colouring, what do you think about driving (speed fuel consumption...) it?

The interior coloring is a bit weird to say the least and not too consistent.
However, one of your main entry doors needs a proper fix, I recommend switching to manual doors as they are less hassle to deal with.
Currently that said door will jam in the open position and be a prime water intake if the ship lists, which will make you capsize.
The other problem is that the main upper deck and the bridge is connected without being separated from this faulty door, causing it to quickly capsize when it lists sufficiently in bad weather or if you hit ground.
