As a start the front strap would go about at the front small triangular window, virtually blocking the window or at the window frame between it and the next window aft.
The rear strap should likely be at the step down between the saloon and the aft cabin with the forward edge of the strap right at the point that the step down joins the aft cabin roof.
That should clear the prop and shaft and lift on the solid part of the*keel.
It's been a while since I've watched one of these vessels come out.
Stop the lift process a couple times as it clears the water and look underneath.
If you can, check some yards in your area and have a look at the underbodies. There is likely at least one of two boats similar to yours.
