Vacanti LOFT 97 Ranking & Summary
Vacanti LOFT 97 description
Vacanti LOFT 97 provides you with an effective and convenient program that makes the design of typical keels and rudders a quick and pleasant task. A planform is designed by simply entering the desired keel or rudder span, leading edge sweep angle, then root and tip chord lengths and thicknesses. Click on one of 5 NACA or NASA foil types from the list included with LOFT. The chosen foil shape will be scaled in thickness to the desired amount at the root and tip and linearly tapered between the root and tip thickness values. Enter the offsets of your own proprietary foils and choose them from the LOFT pick list. LOFT allows your choice of elliptical or parabolic trailing edge shapes that can be adjusted in curvature from virtually straight lines to tortured curves.
If this is a keel design, you can choose a ballast density, top of ballast depth and the angle of the top of ballast. Now click on the CALC menu and LOFT computes 11 ballast and performance values including : Vertical and lateral center of gravity, frontal area, wetted area, aspect ratio, weight, and avverage chord length. Modify any design parameter while tracking the potential performance factors of aspect ratio, wetted area and frontal area.
If a rudder is being designed, and the density of the core material is known, it can be entered as a "ballast". Now the weight of the completed rudder can be estimated without the stock. A lightweight rudder is important to performance in MORC, IMS, IOR or PHRF racing sailboats to minimize pitching moment.
