What fires up my query, how is the dingy sail supported? On inspection there appears to be no mast on the dingy.
I think it's a lateen rig, so there would be a semi-vertical yard attached to the mast at an angle.
Hard to tell with the poor photo quality..

C,mon, guys -- it's photoshopped. Look closely -- there's no mast on the dinghy. (Also for what it's worth, still air.)

I don't believe it is photoshopped, just an example of bad seamanship. They probably left the sail up for the same reason they left their fenders out. They were lazy and they didn't plan on going far. They probably use the dinghy sail to keep the dinghy from riding up on that too short tow line.

The real mystery is, given their laziness in dropping the dinghy sail and leaving the fenders out, why did they set the sails at all?

Hahaha - laziness sailing... AND in photoshopping... zoom in on the dinghy - not only is there no mast, the sail isn't positioned over the dinghy where a sail would actually be, no mast on the dinghy, no mast above the sail, yet a shadow of the mast in the blue portion of that sail... Yeah, real lazy photoshopping...

Haha, no photoshop.
I will be anchored here for a couple months and will keep an eye out for them and their curious floating sail to get better info.

Aren't we just a skeptical bunch... I do hope you get us more info. If that photo isn't photoshopped - how the heck did it come out looking like that???

That's actually a pretty normal artefact of computational photography on modern smartphones. The giveaway is that, where the mast should be, there are two faintly-visible vertical lines. If you look clearly, you can see an identical spacing of vertical lines up the sail where there should be a shadow of the mast, yet only a single masthead. And, if you look around the photo, you will see several examples of vertical lines with identical spacing.

Most phone cameras now use computational photography, which involves capturing a burst of images in rapid succession, then digitally combining them to enhance clarity, reduce noise, and compensate for motion.

In this case, the mast of the smaller boat appears to be missing, with only a couple of faint lines in its place. A likely explanation is that the mast was too thin or faint to be reliably captured across the entire frame sequence - especially if:
  • The mast blended visually with the background (which it does).
  • The boat and/or camera was in motion during capture (likely both were)
  • The image was taken at some distance (which it was, as evidenced by some other indicators)
  • Lighting was low or inconsistent (I don't think this was the case)
  • The phone's algorithms prioritized background stability over transient, low-contrast features
During frame blending, objects that don't appear consistently across frames - especially thin, low-contrast ones - are often treated as noise or ghosting artifacts. The algorithm then suppresses them, effectively blending them out and reconstructing the background instead. This process can create a faint blur or "ghost" where the object partially existed.

That's interesting. I've never seen such a bad interpretation of an image by an image processing algorithm. I don't agree with the "blended visually with the back ground" as there are too many different backgrounds where the mast should be visible. However, looking at the pixel displacement that could certainly be a large factor. It would be interesting to know what the camera/phone was that shot this image and what the image capture settings were.

That's a really bad image interpretation.

Well, I'm not sure we can say that because we don't know what visual data reached the phone's sensors. If you look at the diagonal lines, you see some evidence that this portion of the image was fairly small and was already challenging the limits of the sensors' resolution. In other words there was simply more visual detail than could be captured well at that distance under those conditions (or at that physical resolution).

In short, all indications are that the hardware captured limited visual data which then had to be post-processed to produce the best possible image.

In this case, this post-processing probably did not result in a better image than if it had captured only a single image and made simple color corrections. But, it's tricky. The camera software/firmware has to "guess" at what the person looking at the final image will most value.

This phenomenon is actually very common. Most of the time it goes unnoticed because it often results in a better image. The only reason we noticed/care is because the little thing that got obscured is perceived as important to us. Had it been a power line or something else we did not intend to capture, it would not be missed.

I agree with Foswick - judging by the graininess along some of the other edges it looks like the picture was taken with lots of digital zoom, at the limits of the camera’s capabilities. The problems may have been compounded if the resolution and quality were reduced to shrink the file size for the forum to render. Between all those processes there’s lots of opportunity for things to get a little funny looking.

There are plans for nesting dinghy's that are interesting. Full sized boat. half the space and two
lighter to lift pieces vs. one.


maybe check these out.

I get it but.....

I am completely sold on my 8' inflatable and 1.5 hp motor.
850 lbs capacity, doesn't tip at all, doesn't bang up the boat.

The only drawback is inflatable do not row Worth a lick and I am sure they
do not sail (they do have sail kits) even poorly.

Good luck.

I'd looked at nesting dinghy's years ago and ran across this one that looked quite good. I never did spent the money for the plans (although they used to $25).

I think I might end up with a nesting design. It is probably the only way I will be able to actually sail with two adults and a dog.

I should mention that I reached out to CLC and asked about the possibility of using their Eastport Pram for my use case. They were very helpful. Wasn't the answer I was hoping for, but a quick, clear, and honest response.

What I might do is build their Eastport Ultralight: Eastport Ultralight Dinghy Kit by Chesapeake Light Craft

It is not what I ultimately want (no sail option), but I don't think I will regret having built it. If I want to, I should be able to sell it to pay for supplies to build something else. And, who knows, it might be just fine for us.

So, I am gonna stand corrected, kinda impressed...


I would like to see what is on the under side though.........
