NORTH DESIGN SUITE SOFTWARE

The North Design Suite is an integrated family of specialized software programs that brings unprecedented power and flexibility to sail and rig analysis. Each specialized program can interface with others within the suite, allowing North sail designers and engineers to virtually sail and test a boat in an infinite variety of conditions before construction. NDS significantly expands a designer’s ability to test different sail and rig combinations and accurately measure results. Equally as important, NDS ignificantly reduces tuning and development time after launch. North

Design Suite Software Modules...

1) DESMAN™ ... rig and sail CAD modeling
2) SPRIAL™ ... creates the 3-dimensional sail “mold”
3) 3D LAYOUT™ ... defines the structure of the sail
4) FLOW™ ... applies wind pressure to 3-dimensional sail mold and provides sail forces
5) MEMBRAIN™ ... balances wind pressure, sail shape and rig forces
6) SAIL SCAN™ ... compares actual sail shapes to Membrain predicted sail shapes where possible
7) NORTH VPP™ ... predicts yacht performance with special attention to sail shapes
8) HULL VPP™ ... calculates lift and drag on hull and appendages
9) VIRTUAL WIND TUNNEL™ ... models air flow on upwind and downwind sails
10) RACE MODEL™ ... measures effects of sail/rig adjustments on rating and vice versa
11) SPP™ ... regression analysis to calculate hull forces without existing hull data
12) ROUTER ... predicts sail performance using historical weather over a specific race course or leg
13) DAS BOOT™ ... hull CFD to measure hull drag and appendage lift for the North VPP
14) SAIL COMPARE™ ... overlays Membrain results for comparison
13) SAILECT™ ... shows sail crossovers in a user friendly format
