domain Trying to price a domain

[SALTYDOG]

I own cruisecaptain.com, but really am not using this domain. I have several others that I use instead. I am trying to get some idea what the worth of cruisecaptain.com might be. Thanks for any response.

"cruise captain" in google = 20,900
average monthly search volume in google = "6,600"
no ppc ads

Could work well as a brandable domain.
My guess would be low to mid $xxx, maybe higher to the right buyer.
