a lot will depend on what type of trailer you use.
if its a roller coaster trailer then the boat will come off very easy and you won't need to get the wheel bearings in the water.
if its a bunked trailer then it will have to go further in the water to get the boat off so the wheels may have to go right in as far as possible to get the boat off.
