The problem with Sav's point of view is that it axes the Profession skills. Specifically, he's ignoring the following line from the RAW:
SRD said:
An attempt to accomplish some specific task can usually be retried.
In other words, the RAW say that you can use Profession skills to accomplish specific tasks.
Sav says you can't.
He's therefore wrong, but you'll never get him to admit it.

For a rousing good discussion on the Profession skill - specifically, Profession (Sailor), there's a thread a couple of pages back on the general board on sailing without a crew. I'll try and hunt down a link.
To me, the Profession (Sailor) skill is the skill that is checked against to accomplish daily shipboard tasks:
SRD said:
You know how to use the tools of your trade, how to perform the profession’s daily tasks, how to supervise helpers, and how to handle common problems.
So, if you wanted to set a ship's sails, perform basic damage control, maintain the rigging, and steer the ship, then you'd make Profession (Sailor) checks (and, likely would Take 10 under most circumstances).
If you're Sav, you'd make a Survival check.

I, personally, disagree with that - as you'll read elsewhere - in large part because it makes the Profession skill completely worthless - why would *anyone* take ranks in a Profession skill that confers absolutely no benefits whatsoever?
In other words, the usefulness of a Profession skill is going to be directly related to how *limited* your DM is, and how munchkinny your players are.
One of Sav's main problems with the Profession skill is the possibility to take Profession (Catburglar), and use that as psuedo-ranks in Hide, Move Silently, Open Locks, etc.
If your DM is smart, and your players aren't idiots, you'll never, ever encounter that problem.
In short, allowing Profession skill checks to accomplish specific tasks is not only a good idea, it's a fundamental part of the RAW, and anyone attempting to tell you otherwise is playing around with house rules - which in and of itself isn't bad, except when it makes your primitive plains barbarian a better person to take on a transoceanic voyage than my born-on-a-schooner, sailed-his-whole-life rogue.
