Harbor Master 150-Denier Polyester Water-Resistant Boat Cover, Gray, Model B

The Harbor Master boat cover was a perfect fit for our 21ft flats boat. The cover was very easy to install and comes with easy to read directions. It includes straps that attach to the boat trailer. The straps are long and are very easy to tighten allowing for a secure fit. The cover has built in rear air vents. The cover is made of quality coated polyester fabric. It is durable and waterproof. The air vents help the cover to be breathable to prevent mildew. We are very happy with the quality and ease of use of this cover. I definitely recommend to others.

Very Good item!! Fits perfectly..

This Harbor Master boat cover is nice . It is a lightweight ( 150 denier) material, silver colored. It is trailerable ,includes dual air vents on the backsides and includes many tie down straps. The bow & stern are reinforced too. I had to wait for my boat to dry from all the rain before I could put this on and now its raining again but the water is rolling off . I like this cover .

Super grateful for this Harbor Master boat cover. We got a taste of winter last week so I figured it was time to get the boat out of the lake. This cover protects my most precious from old man winter here in Illinois. Fits perfectly and will keep the elements off my boat.

It repels water good. Keeps leaves and dirt out of the boat. It rides well on the highway. I use it on my 18ft v-hull. The nylon straps fasten to nylon straps that are on the cover. It has plastic buckle type clips. It's small enough to stow away easily.

Our boat is a 16.5 ft alumacraft fishing boat, with front and rear seats with attached yahmaha 50 hp motor. We store it outside in the winter and needed something durable and waterproof for Michigan weather. This cover is that!! The polyester is strong and durable. Was easy to put on. A simple task with the built in shock cords. Didn't have to fight with one end and then the other. Popped it on like a bed sheet. The buckle straps are heavy duty and fit great around the trailer. Was able to pull to tighten easily. Nice bonus that this cover came with a mesh bag for spring and summer when the boat is in use.

I like the material (doesn't get soaked) and it fits like a glove on my 18' bowrider. Just in time. Hopefully it will hold up more than one season, but I'm confident that it will protect my boat through the winter.

The Harbor Master 150D Silver Boat Cover has come in super handy now that the colder weather has come upon us. I need my boat protected from the harsh elements, and Harbor Master is the perfect resolution. Nothing gets in there! My flooring stays bone dry, my equipment remains safe and I have peace of mind that come Spring, my boat will be ready to hit the water in no time! Thank you!

We purchased one of these about 7 years ago. The fabric was thick and it held up great for years. (Our boat is in a covered dock and of direct sun) It eventually started tearing so we purchase a new one last month. Very disappointed with the replacement. The fabric is not the same. Now it's very, very thin and probably would not last more than one season. We returned it.

It clearly says trailerable on the box so we covered the boat and off we go. We reached our destination and found it had come undone at the seam and had been flapping in the wind. I will be returning it.
