If you hold down the "fan" button, it will cycle from automatic mode into manual mode and then through each fan speed. I think on mine it starts at "1" and goes up to "6".
Get a infrared thermometer and measure the air coming out of the vent. The thermometers are cheap to buy now on Amazon and are handy for a bunch of other things. It would be better to know exactly what "moderately cool" means numerically before we can offer a suggestion.
Also, there is a reversing valve on top of the unit that can get stuck. You can gently tap on it with a mallett and it may become "unstuck".

Have you cleaned the mesh filter on the intake of the unit? they do get blocked rather quickly and cut down the cooling ability almost to non existent.

Re: 06 Carver 41 CMY Aft HVAC Issues
I put a few pool tablets in mine this spring, ran the AC awhile, and fixed the same type,problem. Wasn’t a problem with the fan, but wouldn’t cool very well.
