Shaping the lower section and then screwing on the upper part before taking them apart to fit each part to the boat

First using a variable profiler, take the shape off the old section to use as a pattern for the new section.

Having removed a lot of the angle using a power planner taking the rest down with a hand plane to get to the same profile as the original part.

setting up the lower section ready to remove the large part of the angle before final shaping with a hand plane.

Several runs at the lower section and the angle starts to appear 

Once the angle is near to the finished angle the upper section is then fitted 

Then dry screwed in position so that final shaping can be made.
