Question: My moorin may be very windy at time. How do you secure and tight the cover to the boat without fearing it flies away ?
Document: Loved the cover. The only down side was they sent no instructions. We had a rope and two short hooks on a black tie down. Had no idea where they went. My husband figured out the rope goes through the eye lets and under the boat to keep the cover tight.
The cover fit perfectly for what we needed and we got it in less time than expected. My only complaint is that there were no directions.
A little bigger,but it is working! Just in time for the great snow storm of Jan. 2014. A -13* last night.
Absolutely fantastic boat cover! It arrived within days, and we have been using it all summer - not a drop of water has gone through. So pleased with the service and product.
This boat cover is a nice boat cover with a really good price. Price is the main thing I look for, and I couldn't beat it anuwhere.
Great cover for the price. Have had on the boat for about a month. I live in so.cal desert so it gets a lil warm. The cover came gray has started to turn a blue purple. We will c how it holds up through our summer.
Did what I needed, heavier than I expected which is a good thing. Have a 21' 6&#34; boat and it is a little long, but that allowed me to cover the out drive as well. The straps are a little weird. No instructions at all and I didn't use them over the top of the cover, just from the trailer to the clips.
Product is of great quality, you will not find a better price and their shipping is great. It did get held up for a day because of a huge snow storm in the east but their customer service wa great at keeping me informed of where it was at and it fits my boat perfectly! I saw reviews that complained about no directions but if you have had a boat cover before they are all pretty much the same and its not rocket science people. Excellent product
"Awesome product but waaaay too big for my 21' boat. Obnoxiously big actually. Great value but they need a more accurate sizing chart. Also, did not come with enough straps so I used old ones. Recommend to buy, but buy smaller than you need.
Very high quality cover,  especially for the price. You can't beat it!! !
