When you start to think about creating your own custom boat flag, there are several considerations to think about: size of flag, style of flag, your custom design and lastly, "single-sided-reverse" or "double-sided." So what does single-sided-reverse and double-sided really mean? Single-Sided-Reverse Single-sided-reverse (SSR) flags are by far the most common boat flags on the market and with no exception here, we sell far more SSR flags than we do double-sided flags. A single-sided-reverse flag does not mean a 1-sided flag, it is in-fact 2-sided, however, the back side of the flag is a mirror image, so the back side of the flag is actually "reverse" or backwards. Also, the back of an SSR flag is about 95% of the color from the front - this is just because how the flag is created and dyed. Ill show you what I mean in a few photos below. For some flags, having a reverse image on the back is not a problem at all. For example if you have a flag made with just a basic anchor as the design. With a simple design like this, it doesn't matter if you're looking at the front or the back (in reverse) because the design is symmetrical. The flag construction of a SSR flag is still top notch. We use a single piece of 200d Nylon for extra strength and through a chemical process the design is bled into the nylon and locked in. We then stitch on the canvas header and grommets and also do a triple stitch at the end of the flag so it can last you a long-time. Why get a single-sided-reverse flag? So there are 2 reasons why you should get a single-sided-reverse flag: Price: SSR flags are much less expensive. Representation: You're getting a custom boat flag because you want to represent something - a simple SSR flag does the job and does it well. Not to mention, even flags that have words on them, the human brain can read backwards quite well when the flag is in the wind.

In-fact, a true double-sided flag is actually 2 single-sided flags sewn together and that is why they are more costly. To add to the 2 flags, we also put a third layer in the middle, which is a piece of Tyvek to block the sun from going through so the flag reads beautifully on each side. There is no question that double-sided flags are nicer. They read nicer with the sun blocker, and they feel nicer (since it is 3 pieces of material), however, not everyone needs a double-sided flag. It's really up to you. For old boat restorations, sometimes it's a must because you want it to match exactly as the original boat had. Otherwise it's just a personal choice - I guess if money is no object and you can afford the extra 50% (approximate) go for it :) Double-sided (front) Double-sided (back) Here are a few more photos of recent single-sided-reverse and true double-sided flags we have made.
