As it turns out, Overton's, iboats, and many others are reselling Westland covers. I found a couple good reviews of the exact fit covers, and went ahead and bought one from
www.boatcoversdirect.com. The folks at BCD were more knowledgeable on the phone, more transparent on their website, and came very close to Overton's price with their periodic 20% discount code. It showed up in a week, seems to be made well, and fits great. Here are some pics. The color is charcoal tweed. I still need to trim the tiedown straps. $530 for a custom fit Sunbrella cover is hard to beat. I got two local quotes, and both were around $1100.
