What is the equivalent of a surface trim in Onshape?

I am trying to transition into OnShape from Solidworks. As part of this transition, I'm recreating the hull of a sailboat design I've been working on. I've recreated the surfaces that define the form, and now I'm looking for a tool that is equivalent to that of a Surface Trim to create a watertight form. I can't seem to find it in the toolbar. Nor can I find it in the forum. I know it must be here somewhere, but I'm not that familiar yet with the interface.

FWIW, here are a couple other options you can try.
You might have luck extruding a rectangle and using replace face on the 3 faces that correspond to your surfs.
You can also create a rectangle larger than the surface faces but still within the surface bounds. Then use thicken on each surface to remove material. You could also use split, but then you would still have to do delete as a second step.
Split and delete is the only way, at least for now. Least, but not bad, for example, if you choose to split face, you can use even sketch to cut.
Here's a model that I've made sometime ago:

It was done deliberately to test, if surface modeling is possible in Onshape... and maybe, but it forces you to compromise your design.

While waiting for new surface tools, you still should be able to create your model in Onshape.
