"Chip Ahoy" - Installing a Bilge Pump
If you go to this page, and scroll down to the battery article, there is a good picture of the compartment where the winch cable, and scupper through hulls are. This is also about the lowest part of the boat when she's in the water so if this is dry then you have drain hose issues.
Don't forget that water can overflow from the cockpit into the cabin.
The only place I've found that water doesn't drain from is under the forward port dinette seat, and the compartment under the port cockpit lazarette.
