When I mount a full hull to a base, I prefer simple brass tubing to the finials, as sometimes they get too fancy and detract fro the ship.
I simply cut two lengths of brass tube, polish it and clear coat it with gloss, then drill a small hole in the bottom of the hull, and glue a pair of small molly bolts into the model...
Then I go back to building the model, and when I'm ready to mount the model to the base, the molly bolts are already in place, then it's just a matter of tightening them down.
