My experience tells me the fit of the AS parts would be much better. The AS shape appear to me to give better water flow compared to the DS shape. Overlaying the DS lines to the AS lines, shows the waterlines in DS appear slightly hollow forward and are much different than AS waterlines. #Solidworks in delftship softwareRead Sonny Levi’s book on planing hull designs if you need to understand this.Īnyway, checking further I produced a lines plan in my ancient Aship Gen4 software and sure enough get curved edges at the forward frames to hull intersections. This is odd, most boats have curved edges in these frames where they meet the hull plates, a basic requirement of developed plates and conic sections. Fore foot forward frames do not having much curvature against the hull plates. Loading the rep file back into DS to check the shape gave pretty much the same lines plan of the original DS design. The frames outer edges are too straight and only meet the hull plates at the inner and outer edges.Īs part of my investigation of why this occurred, the same data was used to produce a. Problems appeared at the fore foot area with hull plates not wrapping and sitting well onto the frames. The parts were NC cut and the boat started building. The hull plates were un-folded and showed little edge or face stress. Recently completing a 4.5m planning hull design in DS Pro.
