Bring water to boil in a large stewpot. Add lobster tails, salt, and lemon. Cover, bring to a boil, then simmer for 5 minutes. Remove from the heat and let sit for 30 minutes. Drain and cool.
Cut around the edge of the underneath side of the shell and remove the meat. Cut into 1/2" pieces. Place in a large bowl.
In a small bowl, combine the mayonnaise with the curry powder, paprika, and ginger. Add the mayonnaise to the lobster, and add the celery and melon. Combine gently. To serve, place lobster mixture on bed of lettuce, along with lemon wedges.
