How secure do you need? To keep most people out, just writing zeros once, which is under the security options for erasing disks in disk utility will be enough. If they are the kind of people that have hundreds of dollars worth of disk recovery utilities lying around you may want to do the 7 times pass of writing zeros. If they are poking around with 3 letter agency level tools, or willing to spend thousands of dollars for DriveSavers, just writing zeros, even the 35 times option may not be enough. But, honestly, if they were in the later 2, and you are concerned about what you have on the disk, I would take a sledge hammer to it and throw it away before giving it to them.
