Default Side-scan-sonar images of Echo Junior

Hi All,

Kicking around in Alton Bay recently. Decided to try and bag the Echo Junior on SSS (I practice alot on many different targets in New England that I have not dived-then dive them for various reasons, as I did today). Chop was bad from passing boats, as were swells because it sits near a marker warning boats of a shoal so they tend to come close in to the marker when passing by.

But I caught it then dove it, landing about 12 feet away-viz about 5 feet at about 40 feet and no thermocline either-something else I did not expect given my experience diving Winni. I had planned on dropping down in my wetsuit (vs. my drysuit) and hitting ice-cold water and taking the hit for a few minutes-didn't happen.

Wow-not much left-wood was mostly skeleton-like structure with a huge engine standing straight up in the water column about 4 feet off the bottom of the hull. Surprised I could even pick up the tattered wood frame. The engine I expected to see on SSS, but not the framing. This thing is long, too. Must have been a blast to drive.

According to a post I found on the Net about her a while ago:

# Loon Cove - The wreck of the Echo Junior lies in about 45 feet of water on the south side of the red buoy in Alton Bay. The 28-foot hull is still intact. It burnt to the waterline on its maiden voyage. The engine of the 1940s speedboat is a 12-cylinder Allison Aircraft engine.

Sorry the images are not clearer-this one was tough-as I said the hull was pretty much gone and what was left was Swiss-cheese. But the engine stands out nicely as a square with associated rectangular shadow from the sonar beam hitting it.

Image 1: Knowing I had a target to find in the area I decided this was it, and was right; You have to be creative in your interpretation of an image, coupled with experience-I knew there was something solid there; Image is nothing to write home about but was useful to me;

Image 2: Clearly a boat (at least to me), with what I correctly assumed was the engine standing up in the water column; I am still impressed I got a hull outline at all-this hull was toast; Note the shadow of the engine amid-ships;

Image 3: Quickie scan leaving the area-again you can see the engine standing in the water column but the rest of the image is pretty much useless, unless you were looking for something in this area; If that was the case and this was the first image I caught it would have been a major focus-point;

Image 4: Used the zoom-box to blow it up-suffers from pixelation though still useful to me; Image is warped (curved) because I was turning the boat a bit when I caught it-turning boats equal less-than-straight-line images of an otherwise straight object.

More to come as I get to them.
