Mesh Unable to Become Solid From Intersecting Itself

This is my first time ever using AutoCAD 3D for a competition, and my group made a canoe mesh using the EDGESURF command on each quarter of it. I am attempting to have it converted into a solid shape, as I would like to subtract the shape out of a box shape to make a female mold model. However, as I assume from it being too complex, it intersects on itself and is unable to become thick enough to be converted into a solid. I have tried looking around, but have not found a solution. The file with the mesh should be attached. Is it possible to make our canoe mesh into a solid? Please let me know how!

convert the meshes to surfaces.  UNION those together.   That is your female and male mold as it has no thickness.

 

make a duplicate and scale it up for an outer mold or down for an inner mold to make a mating mold giving the canoe its final thickness.

After converting the meshes to surfaces I tried using SURFSCULPT to create a solid (after adding planes to define a watertight volume).  SURFSCULPT was unsuccesful as it was still not finding a watertight volume.

 

I suggest using the section command to define a series of section cuts from the 3D surface model.  Years ago I was involved with a college team building a concrete canoe.  We could use the section cuts to layout the cuts on 2" thick styrofoam to create either a male or female mold.

 

Note that simply scaling a duplicate of a model and then "scale it up for an outer mold or down for an inner mold to make a mating mold giving the canoe its final thicknes" will not yield a shape with uniform wall thickness but may be close enough.  This may be  a moot point as I do not think you need a solid with a wall thickness, just a male or female mold of a "filled in" canoe.
