Is this sercure?

I have passwords based on a phrase giving me a 15 character string (mixed upper case, lower case, numeric and special characters). When I need to register on a site that requires a secure password I apply a prefix or suffix to the base string. I only need to note down the prefix or suffix as the 15 characters is locked in my head (e.g El Reg could be noted as ER_ or _ER). The system does require a bit of tweaking where passwords must be shorter than 17 characters.
