I received many helpful responses and and nearly all with very close to same
approach.
However, following from Jon had what I thought was a useful twist -
referencing part as external geometry so will update if part changes.
Create a new part called volume or something like that. Then using
external geom copy, copy the surfaces from the inside of the vessel into
the new part. It's best to use seed and boundary surface selection so
that it will update as you make changes. Then in your new part, create
the needed surfaces to cap it off and make it an enclosed quilt. Not
just solidify it and you have a part that represents the volume and will
always update as you make changes.
