... Will I need cat trax or some sort of wheels to get the cat from the trailer safely into the water?
CatTrax will last you a lifetime (and many boats). I'd invest in one RIGHT NOW and forgo dumping money into an aluminum trailer. You'll get far more value from CatTrax ... and save maintenance on your hulls (and trailer) by not dragging your boat around on the beach or shore--or dropping your trailer in the water to launch your cat.
