I do have a small storage space in the very tip of the V birth but it's not properly sealed off from the cabin (just a wooden hatch) or designed for draining. So if I made use of it I'd need to be able to seal it off well from the deck. A deck inspection plate might actually be a decent idea where I could just reach down in and pull out the rode.
I have the same thing on my boat. It is just a question of getting in there and glassing up the compartment so that it is isolated from the v-berth, and drilling a drain hole. (there is already a bulkhead there with a fabric cover over the opening) There is even a round void in the non-skid on the foredeck where something like this would fit nicely. I guess it was an option on my boat!
