I would recommend placing at least 2 CO detectors in your cabin. I have one up in the V berth and another one near the engine compartment/aft berth area. When I previously had CO problems, a couple of times the V-berth detector would go off with high readings, but the one near the aft berth didn't. Ventilation was the reason for the descrepancy. I didn't have the forward hatch open, but had the companionway hatch open. CO tends to migrate to and hang out in unventilated or poorly ventilated areas.
