One key to air conditioning in humid climate (practically all marine environments) is the ability of the cooling coil to condense moisture from the air blowing over it. For this to occur, the temperature needs to drop below the dew point, this is pressure dependent but around 60 degrees, you won't get air below that with 60 degree water in the coil. You really want the coil temp 40 or less to cool the air adequately. This is one reason why hydronic cooling systems struggle to work well.
