I cannot recreate the front of this boat

baffour_osei

No matter how many sketches, extrusions, chamfers, etc. I've done, I cannot seem to recreate the front of this boat. The front of the boat in the image has a skinny mid section that goes from the top edge of the boat to the bottom whereas my CAD model's mid section increases in width as it goes towards the bottom. I've even changed the order of my sketches and extrusions. Please help!

Also, how would I create the ridges on the sides of the boat where you can see its width reduce with each one? Thank you! Here's the link to the doc (https://cad.onshape.com/documents/3dc586bfcb9ee313aae79692/w/8acc8396dbade22bc8a3a2df/e/726c0f81a04e6174b7cf16d8?renderMode=0&uiState=6201e557257b2a4fcad6725d) and I've attached 4 images.

You'll probably want to check out surfacing tools such as loft, projected curve, fill, etc.

I would probably approach this by modeling some cross-sections, then lofting between them, optionally with some projected curves used as guide curves. You may need to break it down into multiple lofts to get the ends to behave how you want.

Here is the training on advanced surfacing: https://learn.onshape.com/learn/learning-path/advanced-part-and-surfacing-design

Here's a model I made recently that makes use of some of those techniques to form its hulls, rudders, and sail:

Hope this helps!
