Dude, Where's my GWS10?

Regarding the Garmin GWS10 windvane (PS, March 2014), not mentioned in your review is the insecure vane attachment. The windvane is secured to the shaft with a metal clip. The clip is a slip-fit into the vane. I’ve found that in any serious up draft, the vane flies off, leaving the metal clip secure on the shaft. This is apparently so prevalent that replacement windvanes are discounted on

While we noted the cup attachment, the vane itself also drew our eye. The vane attaches in a similar way as the cups, and is just as fiddly to attach. It isn’t the greatest piece of design by any measure. While we’ve not heard of any other GWS10 vanes flying off in high winds (we will look at this closer in Round 2 of testing), reports include losing a vane while trailering at highway speeds, a bird flying away with a vane, cups lost to icing in a winter storm, and cups and vanes just falling off. We suspect the culprit in most of these cases is a mixture of marginal design, sometimes poor user assembly, and resourceful birds. We just replaced a B&G 508 that was damaged by an osprey. In our research, we could find about 15 negative reports—mostly about the cups. If anyone has found a fix to these issues, we’d love to hear from them. As we said in the article, if you like the Garmin system, the more robust gWind is the best choice. We suspect that the GWS10 vanes will soon be discontinued and replaced by these twin-fin, impeller-type sensors, which earned high marks in our test.

While wind and birds get their share of windvanes, add crowded marinas to the list. In high winds, all of the boats in a crowded marina rock, but not in sync. When one boat heels 15 deg to starboard, and its next door neighbor heels 15 deg port, the mastheads meet and windvanes get punished.

I have been using wag bags for years now. I have a 30 foot sailboat and cannot imagine lugging around 10 to 20 gallons of sloshing sewage in my holding tank. I plan to remove the all head plumbing and the holding tank. the toilet will remain but only wag bags will be used. They fit perfectly in the toilet bowl.
