Re: Whatever rocks/ floats your boat

To "rock the boat" means to upset the situation or cause trouble. So you could say "whatever rocks your world" and mean "whatever pleases you", but not "whatever rocks your boat." Happiness/serenity in the nautical world means a boat floating peacefully on calm water, not rocking.
