I don't always tow with my cover on but when I do I use a 3-piece apparatus to cover my open bow.
There has been plenty of debate here about do you use the cover poles or not when towing with the cover on. My opinion has been the poles and straps don't provide enough support to the cover and might actual allow too much load on discrete points increasing the chance for cover failure, so I never used them while towing with the cover on.
While towing the boat to Fort Lauderdale for the 2012 attempted Bimini trip, the wife took this picture of the cover. You can see how the cover gets sucked into the bow area acting like a parachute. My belief is if I had the poles/straps installed the cover would have sank around the top of pole and potential caused a failure there.
My solution to this problem was to engineer something to prevent the cover from being sucked into the bow area and to distribute the wind load over a large area to protect the cover. As thing usually go I have created something I like but it might be a tad bit over engineered for others.
I have built a 3-piece system that sits on the horizontal fiberglass area of the bow compartment. Why 3-pieces; 1) ease of installation and removal and 2) so that it will fit in the bed of my truck and under the tonneau cover. The system is made out of 1/4" plywood, 1" boards 4" & 6" wide, square lock pins ( 2.25" & 3.5"), and rubber drawer filler material to prevent the wood from scratching the fiberglass. Once the pieces were built I used urethane to coat and protect the wood. The red/white rope you see on pieces is used to hang the panels when not in use.
1st bow piece installed. This is the largest of the 3 pieces.
The second piece installed but not yet secured in place. You install this piece second because the walk-thru window must be closed to install, the window can be opened after the bow piece has been installed.
The third piece installed and ready to be secured together.
The three pieces connected with the old system of 1/4" bolts and wing nuts. The bolts and wing nuts worked fine but took to long to install and take apart, that is why I went to the square lock pins.
With the support leg installed, this carries the majority of the center load. I have gingerly walked across the installed unit and it supports my 200lbs weight with ease.
Ribs are notched so the load is on the fiberglass and not the vinyl cushions.
All pieces installed. I do use the straps and the rear pole. The front part of the straps get pushed down onto the wood bow cover but the aft part the straps do provide some amount of support.
To help support the cockpit area of the cover, beside the cover strap I use two units of grey pvc conduit that forms an arch to help carry the load. My previous boat had a 1" wide fiberglass bar that supported the cover in this location, I use the pvc because that is what I had on hand. The cockpit will see a lot less wind force compared to the bow area but to me it still needs something to be protected the cover.
Picture of cockpit area pvc supports. They are in two piece so that the can fit in the bed of my truck.
I know this system is not for everyone but it works great for me. After a couple of uses the cover still looks new, no apparent stretching of the seams or worn areas.
Also, an added benefit is that I have noticed my trucks on board computer has shown almost 1 mile per gallon increase while towing. I attribute this to the fact the cover is not getting sucked down into the bow area effectively creating a parachute.
