How good does the portable air conditioner work, and how long have you used it?

You generally want about 400 - 500 CFM per Ton* cooling ambient (unheated) air across your condenser.
A smaller window A/C unit of 6,000 BTU/h, would therefore require about 200-250 CFM (outside) airflow.
Typical bilge blower fans are rated between 100 - 150 cfm, roughly half of what you’d need, were they configured to be fully effective.
I cannot imagine circumstances where, even two (150 CFM), bilge blowers would effectively ventilate a cockpit locker, in your proposed application.
I think most of the previous advice to locate the condenser outside (hatch/companionway) is appropriate.

* In North America, a standard ton of refrigeration is 12,000 BTU/h (3517 W).

Installed a 5000 btu unit in the companion way hatch area on my Nimble Nomad Trawler. I remove two of the hatch boards and replace them with the AC unit. I made a board for the AC unit to fit in and it works great. No power issues as the boat has 30 amp service installed. I plug the unit into a GFI panel inside the boat.
