| Roller-furling headsails should be removed from the foils not only do they create windage but the chance of their unrolling is great. |
| Efficiency is the result of many factors, including airflow, combustion, and parasitic losses such as friction and windage. |
| Stripping extra windage is especially important when hauled out and unable to ride with the wind. |
| The backside is undercut and serrated to prevent glare and is dovetailed into the slide with a set-screw for windage adjustments. |
| The rear sight is a simple peep sight that is screw adjustable for both elevation and windage. |
| With that established you can determine bullet drop, windage correction, and your leads for moving targets with relative ease. |
