Layer the ingredients on top of the onions in the stockpot in this order: first the potatoes, salt, and pepper; then the kielbasa, steamer clams, dungeness crab, shrimp, and lobsters. Pour in the white wine. Cover the pot tightly and cook over medium-high heat until steam just begins to escape from the lid, about 15 minutes. Lower the heat to medium and cook another 15 minutes. The clambake should be done. Test to be sure the potatoes are tender, the lobsters are cooked, and the clams and mussels are open. Remove the lobsters to a wooden board, cut them up, and crack the claws.
