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.

You can use the split tool and then delete the excess faces (surfaces) that result: https://cad.onshape.com/help/#splitpart.htm?Highlight=split5

Whoa. This is going to be a lot of work as this part (and all others) become more complex. Are there any plans to release legit surfacing tools in the near future?0

One of my modeling projects has been to recreate the Delorean in Onshape exclusively using surfaces. Though not as easy, it is possible to get very complex surfaces in Onshape. However, surfacing tools are definitely on the roadmap!

Split and delete, thicken and combine is a hack at best. I seam to have to use it every day. We definitely need knit, trim and a lot more ASAP! Go get a hammer. Hit yourself on the thumb with it. Now you understand my life surfacing in OnShape.
@David_Parrott
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.

@David_Parrott yea we plan on having all the necessary surface tools to split, trim, knit patch etc. I can add you to the request.Lou Gallo

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.Fortunately since then we got Feature Scripts to play with, and couple FS could help in surfacing:

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