If it's time to replace, repair or maintain your houseboat canvas you will find discussions below on . . .
You’ll need to find a custom marine canvas shop that can build or replace whatever you need for your houseboat canvas.
With that in mind, let’s go over a few options that will likely be presented to you for the various projects you may be thinking of undertaking.
A Bimini top for a houseboat equals lots of shade and lots of money! Being so large, your frame is oh so important. It’s the bones of the structure, and it needs to be well built and beefy enough to handle the job.
Most of the houseboats around our lake are between 40 and 80 feet, so a bimini top for a boat this big is going to be a solid 10’ to 12’ wide or maybe more. Your frame and fittings should be stainless steel, without exception, and the tubing should be 1” in diameter or possibly 1.25” if your structure exceeds 12’ wide.
After a storm blows through, you can walk around any marina and see frames that have been pulled apart by the storm, hanging off the boat, or have caused other damage.
The reason for this is typically because of the fittings, since many fittings hold onto the frame with a single set screw. One single little set screw is simply not enough to hold these big frames together. In fact, we feel that it’s a safety issue and these single set screws shouldn’t be trusted to hold any size frame together.
What can you do to prevent this issue?
You can drill out your frame where the set screw goes and rivet or tap for a bolt. Or, if you’re not feeling energetic, you can swap all the fittings with double set screw fittings like the ones below.
Stainless Steel Eye End Double Set Screw
Stainless Steel Jaw Slide Double Set Screw
Doing this will give you double holding power at each junction point. If you are having houseboat canvas built, you can have these fittings drilled for you or you can purchase the double set screw version yourself.
Another important point to make about your frame is to pay close attention to the crown. Ask that a proper crown be put into the top when it is manufactured. Too flat of a crown creates water puddling disasters in the fabric.
Houseboat canvas should also be built with zippered pockets for ease of installation and removal.
Make sure your zippers are #10 in size so they will last as long as possible.

Mounting a top this big requires either through bolting or 4 hole mounting brackets on each side.
Anything less and you are asking for trouble.
Make sure your straps are heavy duty and in good condition. Inspect them yearly, and if you see any signs of degradation then make sure to replace them. Also ensure that the snap hook holding the straps is heavy duty, and know that none of the hardware should be plastic. Better yet, replace all the straps with stainless steel support poles and you won’t need to worry about straps at all. This is something you can do yourself if you are handy.

A couple of important points about the canvas itself before we move on.
A growing percentage of marine canvas shops are now using lifetime thread. Believe me, it’s worth the expense to upgrade the thread for your houseboat canvas.! If you already have polyester thread, or lifetime thread is not available to you, be sure to do a yearly tug test in several places on your top. This is a must and should be part of your yearly maintenance. This will help keep you from coming down to your boat and finding a shredded Bimini top. Pull hard, and don’t be timid. The thread should not give way during your yearly tug test. If it does, take it immediately and have it re-stitched. Your thread is degrading and you need to re-stitch the whole thing, not just the seam that is pulling out. Better safe than sorry!
Last but not least, we know it’s a pain, but when you’re not using the top, lower it and put the storage boot on it. Not only will you lower the chances of a storm taking it out, but it will last twice as long.
Houseboat canvas enclosures are the best way to extend your boating pleasure and your boating season. Marine fabricators will build these enclosures in dozens of ways, so we are not going to talk about construction. Of course, some fabrication techniques are better than others, so I would like to touch on a few points that I think might be important to you.
Clear plastic shrinks and this is a fact. So that beautiful houseboat enclosure you just had made, or are thinking of having made, will change.
Here is what you can do!
Every single time you leave your boat, make sure your canvas is snapped and zipped into place…and I mean every zipper and every snap. Taking this step will help to prevent the shrinkage that inevitably occurs with plastic.
If your enclosure has already shrunk, try EZ-Xtend Boat Zippers to relax the fit instantly.

If your thinking of having an enclosure built, here are a few more things to consider.
Railing Weather Curtains
Now, on to your railing weather curtains!
Weather curtains look sharp and add privacy to your deck.
There are 4 ways to install these panels:
Most are self explanatory, but here are a couple of quick points.
Snaps and screws require drilling and extensive installation, so your price will be higher of course.
Roping can give a sharp nautical look when done well to your houseboat canvas, but be sure to use polyester cord since nylon and polypropylene rot quickly.
We use 3/16 Neo-braid and have great success and longevity with low stretch.
If you’re using cable ties, we recommend choosing black ties since they are more UV resistant. They will need changing out from time to time, but you can extend longevity by using super heavy duty cable ties and of course, lifetime thread is a must for your houseboat canvas.
