Because I don’t know.

Wasn't my factory, it was the Reynolds' reign at the C-Dory factory at the time. Pretty sure you and I have the same Diamond Sea Glaze windows; mine aren't "crap." I didn't say it was my advice, only stating what the folks who built the boat recommended. Our windshield cover is the stock item made by King - same Sunbrella as the window covers. It is tight, with 4 attachment points, but that does leave some room for flex in the middle. We do have a little experience with towing this boat - upwards of 40,000 miles now. Any way you wanna do it with your boat is fine by me. Sheesh!

I guess it's time for me to go out on my boat.

No offense intended.

I'd just gotten off my collector car website. Those guys are brutal. I didn't change into my C-brats more genteel website mode quick enough.

My window cover is snapped about every foot to 18 inches across the top and bottom. And three down each side. So when I say drum tight, that is what happens with all those snaps.

So, it sounds like the answer to the posters original question is: "It depends."

Jim,

You and I were probably twins, separated at birth.

Have a great day in the warm sun. 40 Degrees with wind here in northern Utah.

Screw the boat - I am going skiing..... 0 degrees, sun in the forecast, and new snow. Beat that!!!

Ours only has 4 snaps, but is tight--except a couple of times one snap has come loose. Standard Sunbrella. No evidence of abrasion on the glass or frame. We only have a total of about 9,000 miles on this boat towing.

What I have seen is the bra's on both "Toad" or RV fronts get dirt under them, and then abrade paint and glass on head lights etc...so if grit or sand gets under the cover, it can certainly cause problems. I am going to continue to use the cover on the windshield.
