Highlights on Marine Zippers:
Ask a question? Need an answer? Find it here!
In the U.S. there are three big zipper brands that are used on boat cover applications. In order of popularity:
YKK- UV resistant zippers (most common), but have no warranty.
Lenzip - UV resistant zippers that are the only zippers offering a lifetime warranty. They are also YKK compatible.
Riri - UV resistant zippers with a five-year warranty. Riri zipper is not YKK compatible. Riri marine zippers are barely available in the U.S. and I suspect will be totally gone before long.
Marine zippers have been a source of frustration to boat owners for a long time. They begin to break down after continued exposure to the sun's UV rays becoming chalky and brittle. They eventually lose their teeth, or the teeth begin pulling apart. Another big complaint is the zipper sliders break or fall off.
Are there different sizes? Yes there are, and it's important to know which size you have and which size you need to request when you are having custom boat covers built for you.
The most common sizes of marine zippers used in the industry are #5, #8, and #10.
In my shop we use YKK #10 and Lenzip #10.
I keep #8 YKK Marine zippers for replacements on factory manufactured boat canvas. This is because many boat canvas manufacturers use them. If I had a choice, I would never use a #8 marine zipper. My thinking is why go smaller when bigger is available.
Here is a picture of a separating marine zipper with proper terminology starting with #2
Separating means that the zipper unzips and the two sides completely separate from one another

Tip: Determine your marine zipper size (see Actual Size Zipper area above), and keep a dozen extra metal zipper sliders and stainless steel crimp-on zipper stops on your boat for repairs. Salt water boaters should replace their pulls once a year. Stainless steel zipper pulls are available and worth the price. You can keep them for life and use them on future boat zippers as well. Another nice add-on boat zipper option is a lanyard zipper pull. This cord attachment adds additional length and makes the zipper easier to grab and pull.
