Forces on sails apart, which generally prevents heeling. Each sailing craft is a system that mobilizes wind force through its sails—supported by spars and rigging—which provide motive power and reactive force from the underbody of a sailboat—including the keel, centerboard, rudder or other underwater foils—or the running gear of an ice boat or land craft, which allows it to be kept on a course. Without the ability to mobilize reactive forces in directions different from the wind direction, a craft would simply be adrift before the wind. Accordingly, motive and heeling forces on sailing craft are either "components of" or "reactions to" the
MESO-SAILS MESO-SAILS led to an enhancement in detection and possibly an increased effective range at which TDS’s could be detected. The use of MESO-SAILS dropped to 41% during severe thunderstorms watches however, which may suggest some benefit in keeping MESO-SAILS active during severe thunderstorm watches as well. MESO-SAILS Multiple Elevation Scan Option for Supplemental Adaptive Intra-Volume Low-Level Scan (abbreviated MESO-SAILS), is a dynamic scanning option for the WSR-88D, controllable by the operator of the radar, when in VCP mode 12 and 212, and additionally 35 and 215 with the Build 18 update scheduled for October 2017. When active, one supplemental low-level
