it is doable in that boat. In July the wind will be good for the sail. mostly it depends on your experiance. the sea between long beach and cat lsland is called Hurricane Gulch for a reason. it is the ocean so it can get big weather but most of the time it is a very good place to sail. in the afternoon the chop can be a bit much for small boats. I would think you might want to do some daysailing off the coast of long beach to see if you are ready for the ocean before heading to Catalina. for first timers I suggest starting out early and motoring until the wind picks up. in the moring it will be flat water and you will get halfway before the wind comes up. most days this will be up wind to the island. the trip home is the fun one, usually broad reach with following seas.
