travel trailer covers,friend or foe? what are your thoughts?

16 posts in this topic

when It comes to fuel consumption pulling a boat/trailer,what is more cost effective,no cover which offers less resistance maybe?,or cover,which may deflect the wind up and over the boat? with everything being equal,what is the best way to go?

I have a really good travel cover for my boat but almost never use it, only on really long hauls or if I have gear in the boat or if I'm going to be leaving the boat outside overnight or in the rain, etc. I can't say that I've noticed any difference in gas mileage whether pulling with it on or not on.

If I want better gas mileage, I drive slower.

My cover flaps against the sides of the boat causing scratches so I don't use it.

Stuff that needs to stay dry, or out of others hands I pack in the vehicle. Other stuff goes in the boat.

I would think that the cover would help with mileage like a toneau cover does for a truck. I have a cover but don't use mine either while traveling and my boat has a stall in the garage so I don't need it at home either.

I would think a tight fitting cover would help a little. I remove my trolling motor and with a tight custom snap on cover, the boat is pretty smooth. Every little bit helps nowdays.

Thx Slammer,I would like to agree,but do covers that don't fit real tight act as parachutes and reduce gas milage?

I second the no change in gas mileage with or without the boat cover. Granted there may be some, but it's not going to be a huge noticeable difference. Your boat cover is still going to absorb the air flow and create drag no matter how tight your cover is. If nothing else, you're creating a bigger profile to get through the air.

i have never traveled with my cover on it becuase even if its a tight cover to the fiberglass, its still going to rub and leave a mark.

I see a difference in mileage with mine. About 1.5mpg to as much as 3mpg depending on the wind and its direction, so mine is always on. I pull with a truck with a topper so the air spills hard off the back of the truck right into the boat. By having a cover on you allow the air to move along the top of the boat and spill more cleanly off the back as opposed to dumping into the bottom of the boat and up over the transom at the back. If you don't think it matters much take a look at your cover driving down the highway and see the down force it creates on the cover itself, mine is quite dramatic. Yet I have driven down the highway and watched others acting like a parachute, so I wouldn't expect much advantage there.

I have a tiller so I have a nice flat smooth area as opposed to a windshield that will add more drag. Simple aerodynamics. Airplane wings are covered all the way around for a reason to create a difference in pressure for lift and reduce induced drag, they are not open on one side. Form drag is created by the profile of the boat and increases with speed. Because of this even greater mileage is possible by just driving slower. If I drive 68mph instead of 74mph I see an almost 3mph increase depending on the wind, difference in mileage. Each individual vehicle and boat will give you different results so some may see little difference or you might be like me and see a significant difference.

I had my cover cut up the sides so it overhangs around and 1" or 2" so there is no rubbing of the paint and I use a double cover on the motor so no flapping or rubbing on the motor itself. Works for me but your mileage may vary, and with todays gas prices I take advantage of anything that helps my mileage.

In my personal experience , I had a 2025 Pro V tiller pulled with a Suburban . Cover on and off 11.5 mpg sold that boat got a 18 Pro Angler tiller , cover on and off 12.5 mpg same suburban . absolutely no difference the way I drive .The same suburban no boat 18.0 mpg there you have it.

I don't think it makes any noticeable diff. I tow with it off because it is so hard on the cover to tow with it on and a good one is not cheap. I use mine mostly for storage.

    • They are drumming like crazy now. In fact, I even hear them at night. My wife said when she was a teenager growing up in rural Wisconsin, she always thought that drumming sound was the nearby powerstation.    
    • Lilac blooms are here, just haven't opened. Hearing some reports of good finds in the Houston and Lewiston areas of MN. I checked some new public areas today on the MN side. Could be decent later but too cold and wet right now. Will check some early season spots tomorrow but won't hope for much with the cold weather.
    • Nice!  Must have seemed forever waiting.

    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
