    I do it when drawing up the hull sections. Since you already have the hull, maybe split it in 3rds with horizontal planes, and stretch the middle portion (but don’t scale the bottom or the top slices)

    so your saying I don’t have to start over. Just split the hull into thirds and scale the middle portion by 0.6”?

    Yes, I would try that first. 3rds is just a loose term. I would make the bottom layer at the top of the turn of the bilge, and the 2nd plane probably even with the aft deck. It will probably look funny in fusion but I expect most would be masked by the time the boat is sheeted

    Alright! I scaled the middle section by 0.6" still looks pretty good.

    UPDATE:

    Scaled the middle and changed the prop area. 1" prop fits very nicely back there now.

    I'm having a real hard time getting the correct angle of the prop shaft for the size prop I have combined with the motor size (brushed 380, ~1in dia). It's currently at 4.1 degrees. Which seems pretty steep for a small boat like this. Any ideas?

    I got it figured out. I cut the prop area up by 0.25” and moved the motor back back an 1”. That gave me enough space to get a 2.2 degree angle on the prop shaft
