B-Net Testing Testing Dummy

Testing Conclusions Test results indicate that at least 3 net units totaling 60 linear meters (33 poles) are required to safely decelerate the falling skier, when using a single row of nets. Reference Document: Field testing of Barry B-Net Systems used in Alpine Ski Race Course protection

Solution

Conclusions Netting that is to tight will not catch the skier and may cause the skier to ramp up, flip out or slide under the netting. Solution Netting tension should be “loose” between poles, each section is 2 meters in length but should be hung between 1.85 and 1.95 meters *Simple way to get correct tension when setting up is to use you ski boot as a guide to reduce the distance between poles.
