I want to show you how I make the valve. The only drawback is that you need to make two of them. One to inflate, the other to deflate. But it’s still easier than a Boston valve. I can’t post a photo of the boat without permission, since I designed it myself, so I’m posting a photo of the valve so you can understand the principle on a boat with a smooth side inside. If you’re interested, I’ll add more photos.
