Waterline on a 20' and paint questions

[Yamtt125]

So I am finally getting ready to paint the sides and the deck of the boat, and lay on some bottom paint and what not, but I have no idea where the waterline is since I have have never seen this boat floating before. Even if I go to the local boat ramp, there is not nearly enough weight in it to give me a true waterline measurment.

Can any body give me some measurements of the waterline on a 20' SF, So I know how high to apply bottom paint? I will be adding a jackplate with a 5" set back, so that will probably lower the back even more.


Now a question on painting the sides...can imron be applied to areas that will be under water? If so, can bottom paint go over the imron on the lower area of the sides that sits in the water?
