ball height for 2007 seadoo islandia with karavan trailer

Anyone know the ball height? I changed vehicles and the new SUV has the hitch built in so it's a lot higher. Going to need a drop but my driveway is inclined so I can't figure out the height I will need.

If it's for the tandem axle trailer in your profile pic, you'll want the trailer as level as possible so the weight is evenly distributed between the 2 axles.
