To the editor: Wayne Canning’s recent article on emergency steering (“Emergency Steering,” Ocean Voyager 2017) was accurate about how to set up the drogue for emergency steering and how it can slow a vessel too much.
However, our product, the Shark drogue, is the exception to the rules. The Shark doesn’t require the Y-shape setup as described in the article, only the two rodes forming a V-shape. Second, the Shark can be pulled up close to the boat, which dumps out some of the water to reduce drag so the boat doesn’t slow down too much.
