I am proud (?) to say that ours was the first King Marine canvas cover with the portal for the solar panel on a 27. So the patterns should be the same as ours. Before we put the boat in the water in San Francisco it lived on its trailer in a vineyard. It is a very well-made cover and does a good job of keeping all the farm dirt off the topsides. And the solar panel works well keeping the batteries up. It takes some work to tie it down, but what's a few extra minutes messing around with your boat (worth it)? We have no complaints about the workmanship or design. It is not cheap, but it is done well by a reputable company well known to the Ranger cult.
There are two struggles that we have had. The first is that the cover we got does not cover all of the hull. So all the hassles of fading of the dark hull gelcoat if left out in the weather remain. The second is that it is heavy; which is part of making it durable. You get a routine down where one reasonably agile person can get it on and off, but there is some muscling it into place and wrestling it over the mast and bowsprit.
Still, a good idea if "on the hard" for a long time. We tried it while it was in its slip, but the hassle factor > the benefit.
