Question: Are the straps that are connected to the cover the only way to strap it to the boat/trailer?  Can add my own straps/bungee cords?  Place to connect?
Document: Cover is as sold. Put On my boat yesterday. Very happy not to have to use bungee cords. Hope it lasts
At the time of this review I have had the cover for 2.5 months now. I use it to cover a 1998 18FT Bass Tracker and I only use the cover while boat is stored outside and not under tow. The craftsmanship of the material and the seams impressed me as soon as I opened it. It is made of nice thick material. Another plus was the ease of the adjustable straps that wrap around the trailer to hold in place. Very pleased with the purchase.
I purchased this boat cover for my 18' 185 Bayliner. It is defintely worth the price - it fit perfectly and looks great. The built in straps make it easy to tie down (I used to use bungee cords). The fabric is light enough that it can be maneuvered easily. My last cover only lasted a few years and although it is exposed to the elements, I expect that this will be durable enough to last at least that long. Great value!
I have a 23ft. Regal and this boat cover fits perfect. Material is very durable and looks great. I had an old boat cover that was the same brand so I figuered if the old boat cover worked good I could only imagine a new one. Well worth the money and better quality for the same price as the brands at Academy.The only small problem I have is that 4 straps in the middle of the cover don't reach all the way back to be connected.
We just snapped it on the boat at night and when it rained. It kept the boat nice and clean over the summer. This cover, since it was made to attach to a trailer is not so great when the boat is in the water. I imagine you could get in the water and run the lines underneath the boat, but we haven't tried that. The other, OBVIOUS, thing you could do is tighten the elastic strap that runs around the cover so that it gives a snug fit.
It has a loose fit that you can address when you strap it to the trailer but it isn't what I want in rough weather when the boat is in the water. The other problem has been mentioned by many other reviewers. I really, really don't like the pole that holds up the cover. It would be so easy to fix. A slightly stronger plastic and the ability to screw the different pieces together would pretty much solve the problem.
My boat (2006 Maxum 1800MX) is between 17'6&#34; and 18' - this cover doesn't fit well at all. Here are the reasons why:Front clasp - unless your trailer looks like the one in the picture, the front tie strap isn't great. Mine doesn't have the random vertical piece sticking up above the winch, so I have to strap it down around the winch bar, which isn't a huge deal except...Fit - The cover is too long.
I'ts worth to put out a little more for for this quality cover, fits very close to custom cover, except, center post is flimisy that holds cover up from standing water, hard to hold in place while tighting cover other than that I'm pleased with quality and ease of using it.I don't trailer with cover. I would recommend buying again.
He recommended that I get it larger than the measure indicated on the description if there were any doubt about it fitting my 21' bow rider. BEST advice I have gotten in a while as I needed the extra material to get a really good tight synch for winter. GO LONG man if you can. You can always bind the extra to your trailer or some other anchor point.Hope this helps those out there that want to maintain their own boat in a cost effective way.
This boat cover is the best cover I have ever owned. It has withstood the weather and wind. It has built in straps to strap the cover down and it is completely waterproof. I strongly suggest buying one of these if you are a boat owner. Amazon sells this for a price you can't get anywhere else. Believe me, I've been looking for a while now.
