![]() I believe that Garmin and B&G each have somewhat different ways of controlling and displaying laylines, but that Raymarine is the first to enable polars right in the MFD. Note that if you enable a Min & Max Laylines time period, the shaded triangles will show the shift history - 30 minutes was too long - and that if your laylines separate by more than 170 degrees, they disappear (because you’re reaching). Or you can establish target upwind and downwind angles, and then be reminded about what you think your boat can do. Mirrored TWA (True Wind Angle) is the easiest, with the next tack simply calculated as the opposite of whatever angle you’re currently happy with. Then you need to activate a waypoint or route and decide which of the three layline types you want to use. ![]() To see the Ray version above - or any of the sailing features in LightHouse 14 - you first need to choose one of the three boat types that might typically tack to a mark. In fact, current Raymarine, Garmin and B&G MFDs can now all calculate laylines. But let’s walk through the new Raymarine MFD capabilities anyway, and hopefully we’ll hear from sailors who’ve actually used these tools or the similar ones offered by B&G and Garmin… Additionally, most of the features described in the press release are about racing, which I did little of even when I was sailing a lot. But pretending is also why I can’t truly review the new sailing features that came to all current Raymarine multifunction displays last May, thanks to a free LightHouse 14 operating system update. That’s why the screen above seems to show Gizmo exceeding true wind speed while extremely close hauled. When pretending to sail, I go for high performance.
