I’m having trouble creating surfaces from curves for this boat hull. I have tried most of the surface commands with not much luck. I have attached the rhino file. I’m working out of V5. Any help would be appreciated!

If the surfaces need to be developable(boat built from sheet matl), use devloft. In Rhino5 I think it was still a separate download, later versions it is built in and works much better. Using a few good curves will be easier, like the chine, keel, sheer. Good curves will create good surfaces.

Rhino works best with the least amount of curves to form a surface. My recommendation is to hide all but four of the station curves. Then fair a curve through the upper end point of each remaining station and make sure the curve is fair. There appears to be a fair fairbody curve as well. You can try seep two rails by picking the sheer curve and the fairbody curve then seep those two with the section curves. This is certainly one way to get very close to that which you want. All the best, Rob
