THE FIRST TIME I RODE IN A CAR WITH 360-DEGREE Cameras was also the first time I experienced an acceleration curve that pinned me to my seat. My friend enthusiastically showed off the self-driving capabilities of his Tesla Model S. Mad Max mode was memorable, but I was most fascinated by the car's external cameras. It was fun to snoop on unwitting drivers, even if the car's autopilot and self-parking modes were using these external eyes for more-purposeful reasons. I can imagine that Garmin's engineers are familiar with go-park-yourself buttons because the company's Surround View brings 360-degree camera views to select new-build helms. For these boat owners, docking and attaining better situational awareness just got easier. History poorly recorded the first time a recreational yachtsman docked his steed, but stress and shouting were likely involved. After all, there was no auxiliary power or technology to simplify a task that, even today, ends marriages. While Garmin's Surround View system won't automatically dock a yacht (yet), the system employs a six-camera array, a black-box processor, advanced image-stitching capabilities and a Garmin multifunction display to give the helmsman a 360-degree video view around the yacht. Surround View can be used with third-party docking technologies, and in time, Garmin plans to upgrade the system's capabilities. "Even entry-level cars have bird's-eye, 360-degree parking systems that let you see all around the car," says Dave Dunn, Garmin's senior director of marine sales. Surround View "gives you that full 360-degree image around the vessel to help you dock, or when you're going out of the harbor or through a lock or channel. You can see your blind spots." Surround View consists of six Garmin-built, color 1080p daylight video cameras that are daisy-chained together and connected to the processor, which is networked to a Garmin multifunction display runningthe company's Surround View app. The camera array consists of a single forward-looking camera, dual cameras on each board (port and starboard) and a single aft-facing camera. The forward-looking camera is bow-mounted, the four side-mounted cameras are through-hull secured, and the 180-degree stern-facing camera is placed up high. Surround View is cur- rently only an OEM option (see sidebar), but it can work aboard any kind of yacht up to 80 feet length overall. In all cases, boatbuilders work closely with Garmin to ensure that the cameras are properly installed with minimal blind spots. The system captures the feeds from each of its six cameras and stitches them together before sending this composite imagery to the MFD, where it's shown as a real-time, 360-degree video view. Users can also view single-camera feeds, and can pan and zoom within the system's single-camera feeds. Surround View also has Garmin's Visual Bumpers and distance-marker features. Operators can define the Visual Bumper widths, and the system provides a graphical reference-overlaid atop the video feed-depicting water and nonwater objects. Distance markers act like camera lines in automotive-style backup cameras and give operators a precise graphical reference for how far their yachts are from a dock or nonwater object. Visual Bumpers and distance markers can be viewed separately or concurrently. "There is some color differentiation-that's a big part of it-but there's also some [artificial intelligence] and augmented reality built into it," Dunn says. This differentiation is important when docking, but Dunn says the system can also differentiate swimmers, paddleboarders and kayakers from brine. Distances, he says, are calculated based on camera imagery, but laser-based technology such as lidar could potentially be used in the future. Surround View is currently a visual-only system; updates could include other types of alarms. H Surround View is already being used with Volvo Penta's Assisted Docking system (see Yachting, July 2021), a hybrid manual/automated system wit
