I have managed to subtract it now. But when I want to create the mesh I receive an unstated error.
I am trying some manual settings, and will let you know as soon as I have results 
Here I have created two versions, one with manual settings and one with the automatic option. The solution was to add a surface refinement on the boat:
I also increased the ‘Small feature suppression’ under the Advanced settings.

Thanks, now it is working. But not I am having difficulties with the simulation run. I always get this message:
The phase fraction of your multiphase simulation went out of bounds. This may happen due to multiple reasons, mainly a too large time step, poor mesh quality or high-order numerical schemes. Please review your simulation set up and consider a smaller or adjustable time step, ensuring that the Courant number (CFL) does not exceed 1.
Hey, please check these pages:
Cheers!
Hi, my mesh keeps saying this how can i fix it?
An error occurred. Learn more.
When I pressed to learn more it told me to get in touch with the company.
Access to my simulation.
