Hydrodynamics plugin more than one link

edit

Hello all, I'm using the Hydrodynamics plugin on the hulls of a two hull sailing boat along with buoyancy, LiftDrag, motors, waves, and wind. The plugin works just fine when I only enable one link that contains a mesh with rough collisions of each hull, however when I try to use the plugin by enabling the two hull links separately with their own hull collisions, the real time speed drops ~%70.

Is there anything I can do to the hull meshes to increase performance and enable them separately? Or is the plugin only intended for use with a single link at a time?

Thank you!
