Need Some Modeling Direction
(OP)
I need to model an open chock for marine use and have no idea how to go about it. See attached picture.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

The other thing you can do is use a spline for a profile and control the tangency of the ends so you can later mirror your geometry properly.
In this case, however, I think you could simply use a dimensioned arc. Sweep the surface, Trim to shape, Thicken, then add a full radius (or similar) to create the ski-tip shape. Then extrude the base (which will overlap part of your ski-tip shape) and use fillets to merge the bodies. Mirror along lines of symmetry to complete.

Start with good layout/skeleton sketches. When there's surface geometry floating through your model, it is best to anchor it to good layout sketches. Layout sketch entities should be copied into other sketches, not consumed by individual features.
As was said: sweeps w/ guide curves are usually preferable to lofts. With that, swept conics (parabolas, ellipses) behave better than splines. Use pierce constraint to tie section sketches to guide curves.
Sweep, then trim. The natural contour of a surface may not match the outline it is trimmed to. Extend your sweeps (and even lofts) to their natural progression beyond the face edges of your model, then trim to size. Many lofts suck or fail because the desired end-result face edges are used to generate the loft.
Surface-intensive models have a much higher feature count. Be content with this fact. If you try to over-economize on feature count, your model's robustness will likely suffer.
Use folders in your feature tree to keep related features together and organized.

You wrote it does not have to be accurate, just model a block approx size, then use the freeform or shape tools.
