I have the Tracker TV-18 and I bought the cover from Tracker and it just came in last night. I was really impressed with the quality of the material, construction and custom fit to the boat. There were also plenty of straps, 6 per side I think. I'm sure that the same quality (if not more) would be put into a Nitro cover.
Like I said, I just got it last night. I'm someone here has had one longer and can give us both some input on the longevity of the covers.
I have the Nitro 700LXDC cover from Tracker. It is well made and secures tightly over the boat. It's a good cover.
Like most covers, even well fitted ones, it is very difficult to avoid some wind-induced vibration/flapping on the highway. Just be sure to check your boat's finish for any wear caused by a flapping cover. You may need to put a soft blanket underneath the cover for longer trips.
I have the cover in the Bass Pro Catalog for the TV 17 Single Console Aluminum semi v.. Fits perfect and water rolls off perfectly. Trailers Perfect. I do wish I had a snap cover for on the water though. Has anyone modified a coner like this for on the water?
I ordered mine when I ordered the boat from my dealer. I think the BPS ones are cheaper, but the Tracker ones match the color of the boat (mine does anyway) and have the Tracker logo on them. A little of touch class for a small price.
