Well I bought from National covers and found them reasonably priced and the cover that I bought fit great. I have a 20ft Overnighter with no hardtop and I ordered it 2 ft. longer than they recommended. Matter of fact I think I ordered it for a 22 ft. Grady. Glad I did because it fit great and covered the motor also. The one I bought was called the Silver Cloud which was their middle line. Materials seem very good and had it on this winter in New England and it kept tight and when I opened it up everything was dry with very little mildew.
Take a look at their line of covers Ain't bad for the money and saves shrink wrapping every year. That alone helps pay back for the cover. I would have sent you a few pics but I already uncovered and packed it away for the summer.
Happy boating and be safe out there.

I bought the middle range price wise, was $450.00 and I bought extra straps. I think it's on sale now because summers coming and it's like 10% off. Anyway I'm happy with it.

I have trailered with it twice and never had a problem with the extra strap kit.
