    Comments about Shademate Marine Mooring SurLast Twin Pontoon Bimini Top:

    I have had mine for several years. I leave my boat in the water year round. I unfortunately left the top up in a storm last winter and it required some re-stitching and some of the frame is permanently bent. I wish I knew how to replace some of the frame without having to replace the entire top and frame. I can't blame it on construction or design, only myself to blame for beiing too lazy to take it off.

    Comments about Shademate Marine Mooring SurLast Twin Pontoon Bimini Top:

    I bought this to replace my old top for our pontoon. The old one was a double top which connected in the middle, the same as this one, however had different mounting points for the frame.

    I did NOT personally find the frame FLIMSY as another complaint here. I was concerned because the frames are multiple pieces connected, as opposed to a continuous tube like my old ones. Once assembled it appears to be sturdy enough.

    I thought the most difficult part would be mounting the frames to the pontoon railing, but I was WRONG. The assembly of the frames and top before mounting them on the boat are VERY labor intensive, and the instructions were very POOR missing much needed detail! I was able to figure it out but I am an Engineer and a Handyman. I suspect others who are not mechanically inclined would have a very difficult time with this.

    First, as mentioned the frame tubes are not a solid tube, so each side connects to the top "bow" part of the frame via smaller 6" connector tubes which slip inside of them (3" in each end at each connection). Each top has 4 frame tubes x 2 connections each = 8 connectors per top. Multiply 8 connector tubes x 2 tops = 16 connections. EACH of these connections requires drilling 4 holes through the frame tubes with the 6" connector inside of them and then securing them with self-tapping screws that are included. This drilling/securing process also must be done AFTER the top "bow" pieces of the frame are installed into the fabric top. So you are supposed to slip the top "bow" piece into the fabric, align the connections, drill the holes and install the screws.

    Do the math and that is 64 holes to be drilled with 64 screws to install into each hole to assemble the frames! All of this BEFORE you begin mounting it on the boat!! Had the manufacturer pre-drilled these connector holes and tubes it would have dramatically reduced the installation and assembly time.

    The instructions did not provide any details of the drill sizes needed for this frame assembly, nor for the mounts on the boat. They were also missing much detail that would have made this installation easier rather than requiring you figure it out.

    If you have a rear light which you need to run the wire through the rear of the frame, they barely provided enough wire to complete the job, but it worked in the end. I had to use the wire from the old frame to use it as a "fishing wire" to pull the provided wire through because it kept getting hung up when trying to slip it through the long tube of the frame. The instructions for assembling this part were very vague.

    A couple tricks I used in the assembly: (1) pre-drilling the holes for the connectors BEFORE installing them into the fabric top. This because once the parts were installed in the fabric the only step was installing the screws, and I wasn't drilling on top of the fabric and having to deal with it in the way while doing so and metal shavings on the cover. HOWEVER, because these holes are custom drilled at each connection, you will have to keep track of exactly which ends of the frames and connectors are matched to do it this way. To make this easier, I first installed one end of each connector in the side frames (2 holes & 2 screws for each). Then you insert the top "bow" piece at each connection and drill the other 2 holes at each connection. Then you pull the top "bow" pieces out, install them into the fabric cover, and finish the assembly with screws. Again, make sure each top "bow" piece goes back with the SAME side frame connection which you pre-drilled or the holes will not line up. I marked the tube ends on both the side and top "bow" ends before disassembling to assure I matched them up correctly. (2) Before I started any of the connections I laid the 6" connector tubes out and marked a line on the side of each one at 3" with a sharpie to guide me to insert the correct length into each frame. (3) I made a template for marking the rails for installing the mounting brackets (explanation below)

    The best part of the directions was the sheet with the mounting locations dimensioned on the boat, where you mount the brackets on the boat rails. These dimensions were spot on and seemed to work great. There was virtually no detail provided on the mounting bracket installation but it was pretty intrinsic. If you use the provided dimensions it should be OK. I marked the dimensions on the rail for the mounting brackets per the instructions with a sharpie. These dimensions are CENTER dimensions. The brackets are basically 3 " long with the mounting hole for the frame in the center. So I made a 3" template from the cardboard of one of the hardware boxes, and marked a center line on it at 1-1/2". Align this center line on the template, with the lines marked on the rails, and make a line on the rail at each end of cardboard template. Take a mounting bracket and center it between these lines on the rails and you can mark the holes to drill through the rails to mount the brackets.

    Once installed so far everything seems to be good. Unfortunately now because the mounting brackets are in different places on the boat than my old frames the cover does not work so I have to get the cover modified.

    We will see how the bimini tops hold up.

        Yes. There is a panel that zips together to combine the tops.
